Transmission & HV Substation Automation

Smart grids will depend on inter­op­er­a­ble and advanced SAS for a reli­able and secure ener­gy sup­ply in the future.

What is Substation Automation?

Sub­sta­tion automa­tion is the act of auto­mat­i­cal­ly mon­i­tor­ing and con­trol­ling an elec­tri­cal sub­sta­tion by inte­grat­ing sub­sta­tion equpi­ment, intel­li­gent instru­men­ta­tion and con­trol devices, to have bet­ter con­trol over the pow­er dis­tri­b­u­tion grid and reduce the num­ber and dura­tion of out­ages. Like most pow­er sys­tems, includ­ing gen­er­a­tion plants and indus­tri­al facil­i­ties, sub­sta­tions are usu­al­ly auto­mat­ed with a SCADA (Super­vi­so­ry Con­trol and Data Acqui­si­tion Sys­tem). Most com­mon­ly, RTUs (remote ter­mi­nal units) are installed on site to col­lect data from sub­sta­tion equip­ment, sen­sors and IEDs (intel­li­gent elec­tron­ic devices) and trans­fer this data to a sub­sta­tion or con­trol cen­ter SCADA, which visu­al­izes the data and reports fail­ures to the operator.

Through the SCADA sys­tem, the oper­a­tor can remote­ly mon­i­tor the entire sub­sta­tion net­work, send direct com­mands to the RTU, or define automa­tion func­tions with a PLC to enable auto­mat­ed reac­tions against sys­tem failures.

Since full sub­sta­tion automa­tion requires IEDs, com­mu­ni­ca­tions pro­to­cols, and oth­er devices and tech­nolo­gies to work togeth­er, it is also often referred to as sub­sta­tion inte­gra­tion. The term “instru­men­ta­tion and con­trol (I&C) sys­tem” on the oth­er hand, exclu­sive­ly com­pris­es devices that mon­i­tor, con­trol, and pro­tect the pow­er system.

Substation Automation, the Key to Smarter Grids

Sub­sta­tion automa­tion is a top­ic that is rarely addressed by pop­u­lar media, yet it is the back­bone of the often dis­cussed “Smart Grids”, which will play a cen­tral role in our ener­gy future. As key points to con­trol the trans­mis­sion and dis­tri­b­u­tion net­works, the world­wide devel­op­ment of sub­sta­tion automa­tion sys­tems will deter­mine our abil­i­ty to con­front future ener­gy chal­lenges and sta­bi­lize the elec­tri­cal grid.

Con­sid­er­ing the ongo­ing dig­i­ti­za­tion and recent trends, a future in which every piece of elec­tric equip­ment will be car­ry­ing some type of set­ting and require remote con­trol might be a lot clos­er than we may expect. In order to man­age such a large num­ber of data points and inter­con­nect sev­er­al actors and intel­li­gent devices from dif­fer­ent ven­dors with­in one elec­tri­cal grid, substa­tions will need to be con­trolled with advanced and inter­op­er­a­ble automa­tion sys­tems that oper­ate reliably. 

It is thus no sur­prise that grid automa­tion has sign­f­i­cant­ly evolved over the last decade, from lega­cy pro­to­cols and old, cen­tral­ized RTUs with high I/O capa­bil­i­ties, all the way to the newest tech­nolo­gies based on dis­trib­uted IEC 61850 and IP technology.

The dif­fi­cul­ties lie in inte­grat­ing this new tech­nol­o­gy in old­er 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 IEDs (intel­li­gent elec­tron­ic devices such as pro­tec­tion relays, meters…), which must con­nect to old sys­tems at the sub­sta­tion or the con­trol center.

Adptable and User-friendly Solutions for Flexible Designs and Simple Retrofits

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.

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 Profibus DP 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. 

Not only retro­fits are facil­i­tat­ed with our prod­ucts. It also becomes easy to react to any kind of net­work change (big or small) and to set up open and scal­able net­work architectures.

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.

    Time Management

    All iGrid solu­tions 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.

    Network Redundancy

    All iGrid solu­tions can pro­vide advanced redun­dan­cy net­works like RSTP, HSR & PRP (IEC 62439–3) to min­i­mize net­work down­time and max­i­mize reli­a­bil­i­ty and availability:

    • 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

    PLC Automation

    All iGrid solu­tions can exe­cute logical/mathematical func­tions and automa­tion sequences with super high speeds thanks to their PLC capabilities.

    The inte­grat­ed PLC is high­ly scal­able and has been applied in all kinds of fields to solve a broad vari­ety of challenges.

    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.
