MV Substation & Distribution Grid Automation

Smart com­mu­ni­ca­tions for advanced and effi­cient automa­tion sys­tems in sec­ondary grids

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.

MV Substation Automation, Smarter Gear for Smarter Secondary 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.

In order to man­age the required 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 like pro­tec­tion relays, meters…), which must con­nect to old sys­tems at the sub­sta­tion or the con­trol center.

Adaptable and User-friendly Solutions for Simple Set-Ups and 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. Thanks to its con­fig­urable inter­nal inputs and out­puts and its capa­bil­i­ty to com­mu­ni­cate via Eth­er­net, ser­i­al and GPRS (3G, 4G), the iRTU is thus the per­fect device for MV applications. 

It can col­lect data from a few sen­sors and switchgear con­trollers and trans­fer the data to a any con­trol cen­ter or col­lect data and con­trol thou­sands of devices accross the network.

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.

Fully Flexible Data Collection for MV Distribution Substations

Devel­oped explic­it­ly for sub­sta­tion automa­tion, all devices and soft­ware sys­tems by iGrid T&D pro­vide an exten­sive range of func­tion­al­i­ties and char­ac­ter­is­tics to over­come present and future chal­lenges in the most effi­cient ways.

Fur­ther­more, our solu­tions can col­lect data from thou­sands of devices at once, process and con­vert the data and trans­fer it to mul­ti­ple enti­ties in the net­work. 

Since we have com­mu­ni­cat­ed with equip­ment from numer­ous dif­fer­ent ven­dors in a broad vari­ety of appli­ca­tions, we have expe­ri­ence in com­mu­ni­cat­ing with and cre­at­ing a bridge between all kinds of sys­tems, includ­ing new and old relays and sub­sta­tion gear, Eth­er­net and ser­i­al, IEC 61850 and old lega­cy pro­to­cols (like SPA-bus), SCADA sys­tems and intranets, gen­er­a­tion and ener­gy market. 

Our solu­tions ensure that you no longer need to wor­ry about inter­op­er­abil­i­ty and net­work inef­fi­cien­cies. Our RTUs can com­mu­ni­cate using numer­ous pro­to­cols via GPRS, Eth­er­net or ser­i­al con­nec­tions as well as col­lect aux­il­iary sig­nals using dig­i­tal I/Os and ana­log inputs.

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.

    iConf Tool

    iConf has been specif­i­cal­ly devel­oped for elec­tri­cal appli­ca­tions, sav­ing you lots of time and mon­ey through­out the con­trol sys­tem set-up and main­te­nance tasks, whilst also min­i­miz­ing your project risks. You can use the soft­ware tool to con­fig­ure all igrid devices and soft­ware sys­tems as well as design IEC 61850 projects, to up and down­load your con­fig­u­ra­tions, and cre­ate your own tem­plates. 

    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 62531 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.

      Full Independence for an Open Architecture

      All of our prod­ucts sup­port sev­er­al types of com­mu­ni­ca­tion media, such as wire­less (GPRS/ 3g, 4g), VSAT, ana­log radio, Eth­er­net or Ser­i­al, and can com­mu­ni­cate with the entire iGrid T&D pro­to­col suite. Thanks to our expe­ri­ences with devices from almost all known ven­dors and our pledge for stan­dard pro­to­cols, we can ensure the seam­less inte­gra­tion of our prod­ucts with any third par­ty devices.

      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 reach dis­con­nect­ed devices)
