IEC 61850 Substation Automation 

Why stick to Mod­bus, when you can migrate to IEC61850 today?

What is IEC 61850?

IEC 61850 is an inter­na­tion­al stan­dard that was devel­oped to improve the inter­op­er­abil­i­ty and com­mu­ni­ca­tion between intel­li­gent elec­tron­ic devices (IEDs) at sub­sta­tions. Unlike Mod­bus, DNP3 or IEC 60870, which are sig­nal-ori­ent­ed pro­to­cols with vary­ing data struc­tures, IEC 61850 is object-ori­ent­ed, mean­ing it defines the abstract data mod­els with a stan­dard­ized nomenclature.

Con­sec­u­tive­ly, IEC 61850 GOOSE, MMS and SMV pro­to­cols allow to map IEDs uni­form­ly and do no longer require ven­dor-spe­cif­ic libraries to dis­close the mean­ing of each data point. Due to the many advan­tages it holds for the future, the stan­dard has gained a firm posi­tion over the years and is now also applied beyond its orig­i­nal field of pow­er sys­tem automa­tion, e.g. in dis­trib­uted ener­gy resources (DER).

Why use IEC 61850?

  • High­er speeds using IEC 61850 GOOSE, MMS and SMV pro­to­cols on an Eth­er­net network
  • Flex­i­ble and sophis­ti­cat­ed log­ic schemes (e.g. inter­lock­ing or load shed­ding) for sub­sta­tion pro­tec­tion and automation
  • Sign­f­i­cant cost sav­ings from reduced inter-wiring and no need for exter­nal pro­to­col converters
  • High­er adapt­abil­i­ty from rely­ing on soft­ware con­fig­u­ra­tion rather than hard­wired sig­nal paths
  • High­er net­work effi­cien­cy with advanced IEC 61850 GOOSE sup­port­ed VLAN and pri­or­i­ty tag­ging func­tion­al­i­ties via IEEE 802.1Q
  • High­er reli­a­bil­i­ty with GOOSE’s con­tin­u­ous and inher­ent com­mu­ni­ca­tion and data integri­ty checkups.
  • Improved redun­dan­cy with PRP and HSR, pro­vid­ing zero reac­tion time

iGrid T&D Advantages

  • Migrate smooth­ly and step by step, from con­ven­tion­al or lega­cy sub­sta­tion automa­tion sys­tems to IEC 61850 based SAS with any iGrid T&D prod­uct you need.
  • Ben­e­fit from the easy-to-use iCon­fICD tool to cre­ate SCL files.
  • Use devices simul­ta­ne­ous­ly as data servers and data clients (all iRTU & iGW).
  • Map inter­nal I/Os or exist­ing IEDs (e.g. using Mod­bus RTU or IEC 60870–103 ) onto IEC 61850 log­i­cal devices using the iRTU as data server.
  • Col­lect all data in real-time and from mul­ti­ple servers simul­ta­ne­ous­ly using IEC 61850 or any oth­er stan­dard pro­to­col with iCon­trol SCADA or map it to IEC60870‑5–104 or DNP3 with the iGW to report to 3rd par­ty con­trol centers.
  • Col­lect data com­fort­ably and fast (under 3ms) with IEC 61850 GOOSE com­pli­ant iRTUe expan­sion units.

IEC 61850 Substation Automation

Using interoperability to unlock new potential

Con­sid­er­ing the ongo­ing dig­i­ti­za­tion and upcom­ing chal­lenges in the ener­gy sec­tor, a future in which every piece of elec­tric equip­ment will be car­ry­ing some type of set­ting and require remote mon­i­tor­ing and/or con­trol might be a lot clos­er than many expect. Man­ag­ing such a large num­ber of data points and com­mu­ni­cat­ing between dif­fer­ent IEDs from sev­er­al ven­dors, required the def­i­n­i­tion of a new, inter­na­tion­al­ly stan­dard­ized com­mu­ni­ca­tion design – mov­ing away from old ser­i­al port pro­to­cols to abstract, pro­to­col-inde­pen­dent data models.

The answer to this was the IEC 61850 stan­dard. Since its first intro­duc­tion, it has under­gone many updates and exten­sions, matur­ing to a point at which sub­sta­tions all over the world are being auto­mat­ed ven­dor-inde­pen­dent­ly in com­pli­ance with the stan­dard. It is expect­ed that the effect of the IEC 61850 stan­dard as a com­pat­i­bil­i­ty enabler in pow­er sys­tem automa­tion will be com­pa­ra­ble to oth­er ground-brak­ing spec­i­fi­ca­tions, such as the effect of html on web ser­vices in the 90s. Final­ly, we can for­get mul­ti­ple pro­pri­etary pro­to­cols and unlock new poten­tial by turn­ing to ful­ly inter­op­er­a­ble sub­sta­tion automa­tion sys­tems (SAS) based on IEC 61850 technology. 

Migrating to IEC 61850 can be simple with the right support

Although IEC 61850 is the solu­tion to many inter­op­er­abil­i­ty chal­lenges, migrat­ing to IEC 61850 can look over­whelm­ing at first. The co-exis­tence of old and new gen­er­a­tion devices com­ing from an increas­ing num­ber of ven­dors with an increas­ing num­ber of pro­to­cols is mak­ing today’s elec­tri­cal net­works more and more com­plex, affect­ing sys­tem design, imple­men­ta­tion and maintenance.

At the same time, the chang­ing ener­gy land­scape and dig­i­ti­za­tion require new ser­vices and func­tions, mak­ing it even more dif­fi­cult to suc­cess­ful­ly imple­ment and under­stand mod­ern sub­sta­tion automation.

Migrat­ing to IEC 61850 and get­ting the new exper­tise to employ­ees can thus be a dif­fi­cult challenge.

At iGrid T&D, our sup­port and imple­men­ta­tion engi­neers will help you over­come this chal­lenge. Their role is to make sure that our solu­tions based on IEC 61850 turn out to be the best solu­tion for you and that you are pre­pared to inde­pen­dent­ly devel­op new IEC 61850 projects in the future.

Flexible and user-friendly solutions for a smooth transition

One of the major chal­lenges of sub­sta­tion automa­tion lies in inte­grat­ing new sub­sta­tion tech­nol­o­gy such as IEC 61850 in old­er, exis­tent sub­sta­tions, where old and new devices have to coex­ist and com­mu­ni­cate with each oth­er. Exam­ples of this can be new con­trol cen­ters that have to com­mu­ni­cate with old automa­tion sys­tems or new­ly installed intel­li­gent elec­tron­ic devices (IEDs), which must con­nect to old sys­tems at the sub­sta­tion or the con­trol center.

Solu­tions by iGrid T&D have been designed for exact­ly this kind of chal­lenges. Devel­oped explic­it­ly for sub­sta­tion automa­tion, all devices devices and soft­ware sys­tems, com­pris­ing RTUs, gate­ways, I/O exten­sion units and SCADA sys­tem, pro­vide a unique range of com­mu­ni­ca­tion pro­to­cols and con­nec­tiv­i­ty options.

The devices can use almost all pro­to­cols to both col­lect and trans­fer data from and between devices and enti­ties and can map all of them onto IEC 61850.

Amongst oth­ers, the com­mu­ni­ca­tion pro­to­cols include:

Master/Slave IEC 60870–5‑101 Master/Slave IEC 60870–5‑104
Master/Slave Mod­bus TCP/UDP and JBUS (mas­ter) Master/Slave Mod­bus­R­TU
Master/Slave DNP3.0 (ser­i­al, UDP, TCP) Mas­ter IEC 60870–5‑103
Mas­ter IEC 60870–5‑102 Mas­ter DLMS
Mas­ter Spabus, Mlink, Procome Mas­ter IEC 62056–21
SNMP Agent/Manager IEC 61850 MMS Client/Server                
IEC 61850 GOOSE Publisher/Subscriber OPC UA

 

Our solu­tions can also com­mu­ni­cate through tech­nolo­gies from oth­er indus­tries like mySQLweb ser­vices and OPC UA.

Fur­ther­more, the devices have com­mu­ni­cat­ed with equip­ment from numer­ous dif­fer­ent ven­dors in a broad vari­ety of appli­ca­tions. We have con­nect­ed it all: new and old sys­tems, Eth­er­net and ser­i­al, IEC 61850 and old lega­cy pro­to­cols (like SPA-bus), SCADA sys­tems and intranets, gen­er­a­tion and ener­gy market. 

It is our pri­or­i­ty at iGrid T&D to sup­port the devel­op­ment of your sub­sta­tion automa­tion sys­tems and pre­pare your staff in a sim­ple yet tech­no­log­i­cal­ly sound way. For this rea­son, we used our know-how to design hard­ware that can be eas­i­ly adjust­ed to your needs with our free iConf tool. iConf now also includes the pow­er­ful iCon­fICD tool, which has been par­tic­u­lary designed to facil­i­tate the con­fig­u­ra­tion of IEC 61850 devices. 

With our state-of-the-art prod­ucts we want to make the tran­si­tion to advanced automa­tion sys­tems as smooth as pos­si­ble. Our solu­tions ensure that you no longer need to wor­ry about inter­op­er­abil­i­ty and net­work inef­fi­cien­cies. Our RTUs and gate­ways can com­mu­ni­cate using numer­ous pro­to­cols via Eth­er­net or ser­i­al con­nec­tions and inte­grate seam­less­ly with our intu­itive soft­ware solu­tions, which come with all func­tion­al­i­ties you need. 

With our prod­ucts, you will not only improve the effi­cien­cy of your ener­gy sys­tems through­out the entire life-cycle, but also be able to:

  • com­fort­ably react to any kind of net­work change (big or small)
  • set-up open and scal­able net­work architectures
  • retro­fit third par­ty devices

Our devices are already con­fig­urable and ver­sa­tile by design, but we also pro­vide fur­ther prod­uct con­fig­u­ra­tions and tai­lored ser­vices upon request.

 

Our gate­ways, SCADA sys­tems and RTUs also pro­vide real­ly pow­er­ful func­tion­al­i­ties like advanced redun­dan­cy schemes, inter­nal PLC automa­tion and high-pre­ci­sion, microsec­ond time management.

Hot-Standby Redundancy

All of our devices can oper­ate in hot-stand­by redun­dan­cy mode:

  • Hot-stand­by server/device is updat­ed continuously
  • Clients and IEDs auto­mat­i­cal­ly switch to the hot-stand­by server
  • Ser­i­al loop redun­dan­cy (hot stand­by gate­way acts as a (vir­tu­al) ser­i­al port to arrive to dis­con­nect­ed devices)

Network Redundancy

All of our devices can pro­vide RSTP, HSR & PRP (IEC 62439–3) redundancy

  • Mod­ern sub­sta­tion automa­tion with­out pack­et loss­es and latencies
  • Invis­i­ble to the appli­ca­tion and usable by most indus­tri­al Eth­er­net protocols
  • For appli­ca­tions requir­ing high avail­abil­i­ty and quick switchovers
}

Time Management

All of our devices are capa­ble of high pre­ci­sion time-syn­chro­niza­tion (<1ms) via PTP or NTP and car­ry inter­nal Real-Time Clocks with a an accu­ra­cy of 1ppm. This allows to keep on record­ing events with a micro-sec­ond time stamp­ing accu­ra­cy, even when con­nec­tion to the time source (mas­ter­clock) is lost, per­mit­ting to trace fail­ures back meticulously.

    Not only iGrid T&D but also our group part­ner Thytron­ic, Ital­ian mar­ket leader for pro­tec­tion relays, is active­ly invest­ing in IEC 61850 tech­nol­o­gy. The nov­el X MORE series fea­tures native IEC 61850 sup­port includ­ing the stan­dard­’s hor­i­zon­tal GOOSE (Gener­ic Object Ori­ent­ed Sub­sta­tion Event) com­mu­ni­ca­tion protocol. 

    By com­bin­ing Thytron­ic relays and iGrid T&D mas­ter devices and iRTUe exten­sion units, peer-to-peer GOOSE com­mu­ni­ca­tion can be used over an Eth­er­net-based sub­sta­tion net­work (replac­ing hard-wired block­ing sig­nal paths between switchgears) to enable sophis­ti­cat­ed log­ic schemes for sub­sta­tion pro­tec­tion and automation.

    Some of the most wide­ly known and accept­ed exam­ples are inter­lock­ing bus­bar pro­tec­tion schemes, cir­cuit break­er fail­ure pro­tec­tion, pow­er qual­i­ty con­trols of par­al­lel pow­er trans­form­ers and selec­tive arc fault protection.

    Inter­lock­ing schemes are par­tic­u­lar­ly pop­u­lar as they take advan­tage of the increased speed and secu­ri­ty pro­vid­ed by GOOSE mes­sag­ing, in addi­tion to being a tra­di­tion­al­ly sim­ple and effi­cient method to pro­tect bus­bars in dis­tri­b­u­tion substations.

    So how does inter­lock­ing work? 

    When a fault occurs on the bus­bar, the inter­con­nect­ed relays quick­ly coor­di­nate, caus­ing the relays of the incom­ing feed­ers to block the relays of the out­go­ing feed­ers and then trip the CB of the incom­ing feed­er. The same hap­pens vice ver­sa when a fault aris­es on an out­go­ing feed­er and the relays of the incom­ing feed­er are pro­hib­it­ed to act. 

    Max­i­mum Speed with GOOSE

    Since GOOSE mes­sages are sent relay-to-relay, through an Eth­er­net LAN and thus there is no addi­tion­al delay from inter­me­di­ary equip­ment such as input fil­ters or aux­il­iary relays. The block­ing sig­nals can be sent faster than in tra­di­tion­al, hard­wired inter­lock­ing schemes. Peer-to-peer com­mu­ni­ca­tion allows to send block­ing sig­nals to all relays at once, mak­ing the total oper­at­ing time inde­pen­dent from net­work size, com­plex­i­ty or topol­o­gy.
    With the fast pro­cess­ing time of iRTUe I/O exten­sion units you can ful­ly take advan­tage of this speed. iRTUes can direct­ly com­mu­ni­catate with realys, inte­grat­ing ana­log and dig­i­tal pow­er qual­i­ty mea­sures to the scheme with almost no delay.

    GOOSE Also Pro­vides High­er Reli­a­bil­i­ty and Adaptability 

    In addi­tion to the native secu­ri­ty fea­tures of inter­lock­ing schemes, the oper­a­tional reli­a­bil­i­ty can be fur­ther enhanced by the inher­ent super­vi­sion of GOOSE mes­sages. When a block­ing cir­cuit is bro­ken, unnec­es­sary trip­ping is avoid­ed as the block­ing is not being issued. Instead of ren­der­ing the pro­tec­tion inop­er­a­tive in such a case, GOOSE’ inher­ent super­vi­sion gen­er­ates an alert to ini­ti­ate the maintenance/repair process and react as quick­ly as possible. 

    This super­vi­sion func­tion can also be utilised to adapt to appli­ca­tion require­ments. Depend­ing on the object to be pro­tect­ed, one func­tion must often be pri­or­itzed over anoth­er. For instance, it may be nec­es­sary to sac­ri­fice some oper­a­tion speed in order to achieve selec­tiv­i­ty or vice ver­sa. Such adjust­ments can be eas­i­ly made to the con­fig­u­ra­tion of the GOOSE ser­vice in order to obtain the best pro­tec­tion possible.

    Why opt for the full Thytron­ic Group Pack­age? 

    Aside from the advan­tages that Thytron­ic Group prod­ucts offer indi­vid­u­al­ly, exe­cut­ing a project under one umbrel­la brings many pos­i­tive syn­er­gies, spe­cial­ly in terms of coor­di­na­tion and inter­face engi­neer­ing between products.

    This leads to sign­f­i­cant cost and time sav­ings for the cus­tomer, who also ben­e­fits from:

    • A sin­gle con­tract for the entire package
    • Cost-effec­tive pro­vi­sion, sup­ply and project management
    • A sin­gle point of con­tact for the entire project
    • Quick­er start­up, comis­sion­ing and engineering
    • Reduced cus­tomer risk

    IEC 61850 explained

    The IEC 61850 stan­dard was a response to the grow­ing need for high­er and deep­er lev­els of con­trol and automa­tion in elec­tri­cal grids. With steadi­ly increas­ing num­bers of devices, device types and data points, fur­ther accel­er­at­ed by dig­i­ti­za­tion, as well as the inte­gra­tion of new, often geo­graph­i­cal­ly dis­trib­uted and het­erege­nous, gen­er­a­tion sources, it became evi­dent that future demands could not be met with the tech­no­log­i­cal lim­its of ser­i­al pro­to­cols like Modbus. 

    In order to guar­an­tee inter­op­er­abil­i­ty in the face of rapid tech­no­log­i­cal devel­op­ment and prod­uct inno­va­tion in the indus­try, the IEC 61850 stan­dard not only defines var­i­ous com­mu­ni­ca­tion pro­to­cols and inter­faces, but also pro­vides spec­i­fi­ca­tions con­cern­ing the sub­sta­tion mod­el­ling, con­fig­u­ra­tion lan­guage and data mod­els. For this rea­son, IEC 61850 is com­mon­ly referred to as “not just a pro­to­col” and often called a data mod­el or frame­work instead. 

    The scope of the stan­dard allows to map the stan­dard­ized data mod­els and ser­vices onto server­al com­mu­ni­ca­tion pro­to­cols and thus trans­fer the data via Eth­er­net using dif­fer­ent pro­to­cols for dif­fer­ent require­ments and appli­ca­tions, as for exam­ple TCP/IP-based pro­to­cols for clients/server com­mu­ni­ca­tions. For this rea­son, despite its ini­tial focus on sub­sta­tion automa­tion, the flex­i­bil­i­ty of IEC 61850 has spread its use to oth­er appli­ca­tions, such as the inte­gra­tion of dis­trib­uted ener­gy resources (DERs) into the pow­er sys­tem or the com­mu­ni­ca­tion between intel­li­gent devices in Build­ing Man­age­ment Sys­tems (BMS).

    The IEC 61850 stan­dard dis­tin­guish­es itself through the fol­low­ing elements:

    Abstract Com­mu­ni­ca­tion Ser­vice Inter­face (ACSI)
    The ACSI (defined in IEC 61850–7‑2) describes the func­tions and ser­vices for the inter­ac­tion between IEDs in the sys­tem. Exam­ples of IEC 61850 ser­vices include the trans­mis­sion of files, read­ing of data or assig­ni­tion of val­ues. The ACSI can be mapped onto var­i­ous pro­to­cols, includ­ing MMS or web services.

    Sys­tem Design and Struc­ture
    The func­tions of the IEC 61850 stan­dard are the often-heard log­i­cal nodes, which can sim­ply con­tain device descrip­tions but usu­al­ly rep­re­sent a real phys­i­cal device like switch­es, sen­sors or IEDs, and its entire range of functionalies.

    IEC 61850 Pro­to­col Suite
    The IEC 61850 stan­dard defines sev­er­al dif­fer­ent pro­to­cols for dif­fer­ent pur­pos­es in sub­sta­tions and oth­er facilities/ utilities.

    The stan­dard defines the low-lev­el (process bus) client/server based GOOSE/GSSE (Gener­ic Object Ori­ent­ed Sub­sta­tion Events) pro­to­col to trans­mit event data across net­works at very high speeds. This enables to new pos­si­bil­i­ties for advanced sub­sta­tion automa­tion and pro­tec­tion func­tions and schemes.

    It also defines the more com­plex MMS (man­u­fac­tur­ing mes­sage spec­i­fi­ca­tion) pro­to­col for com­mu­ni­ca­tions between servers and clients. It pro­vides a set of func­tions that allows the client to obtain the data mod­el of the serv­er, read or mod­i­fy indi­vid­ual val­ues, or even delete entries as well as to trans­fer files.

    The last two pro­to­cols dis­played on the chart com­prise the Sam­pled Val­ues (SV) pro­to­col for the trans­mis­sion of dig­i­tized instan­ta­neous val­ues of pow­er sys­tem quan­ti­ties, main­ly pri­ma­ry cur­rents and volt­ages and time syn­chro­niza­tion pro­to­cols such as SNTP over UDP/IP.

    IEC 61850 Projects

    HV Substation Automation with IEC 61850

    In this HV sub­sta­tion automa­tion project the tran­si­tion to IEC 61850 is made pos­si­ble with the iGW-S3 (Eth­er­net switch mod­el) which com­mu­ni­cates with the Pro­come pro­tec­tion relays and maps all their infor­ma­tion (includ­ing sig­nals, alarms, mea­sures and com­mands) into IEC 61850 log­i­cal devices.

    MV Grid Automation with IEC 61850

    In this project iRTUe expan­sion units help the iRTU col­lect data data via IEC 61850 in order to auto­mate 9 medi­um volt­age sub­sta­tions at the Sabi­ha Gökçen Air­port (Turkey)

    HV Substation Automation SCADA

    In this project, the iCon­trol SCADA and iRTUs com­mu­ni­cate with numer­ous meters and pro­tec­tion relays from dif­fer­ent man­u­fac­tur­ers using a vari­ety of pro­to­cols such as Mod­bus, IEC60870‑5–103 or IEC 61850. iCon­trol reports to the exist­ing con­trol cen­ters via IEC 104 and DNP3.

    Sleep Peacefully with Expert Cyber Security 

    iGrid T&D enforces sev­er­al lay­ers of secu­ri­ty mea­sures guid­ed by the propo­si­tions of the IEC 62351 stan­dard to pro­tect its devices from all kinds of threats.

    Our hard­ened devices fea­ture Role Based Access Con­trol (RBAC) to avoid intrin­sic risks such as secu­ri­ty holes and unau­tho­rized actions by authen­ti­cat­ed users.
    In addi­tion to end-to-end encryp­tions via TSL/SSL, HTTPS, SSH and stan­dard pro­ce­dures for VPNs (e.g. Open­VPN), its com­mu­ni­ca­tion can also be secured with net­work con­trol meth­ods such as fire­walls, IP fil­ters, ACL or TCP port blocks.
