iGW-VM – Substation Automation Software

Any hard­ware runs smooth­ly with the scal­able and easy-to-use iGW-VM automa­tion soft­ware.

Our sub­sta­tion automa­tion soft­ware has been devel­oped to con­trol and mon­i­tor any sub­sta­tion (HV & MV). It sup­ports all archi­tec­tures based on Win­dows or Lin­ux servers, as well as embed­ded con­trollers, act­ing as a sub­sta­tion gate­way, bay con­troller, RTU or com­mu­ni­ca­tion front-end for SCADA sys­tems.

The data col­lec­tion from meters, pro­tec­tion relays, and oth­er IEDs can be man­aged using any pro­to­col, inl­cud­ing IEC 60870–5, IEC 61850 (MMS/GOOSE), DNP3, DLMS, Mod­bus or Pro­come. Fur­ther, the iGW-VM can also process and trans­fer the data to one or mul­ti­ple con­trol cen­ters and SCADA mas­ter sta­tions using upstream pro­to­cols such as IEC 104, IEC 101, TASE2.0/ ICCP (IEC 60870–6), IEC 61850–90‑2, DNP3, and Mod­bus RTU/TCP.

Amongst its state-of-the-art fea­tures, the iGW-VM is able to pro­vide load shed­ding func­tion­al­i­ties, high accu­ra­cy time stamping/processing (<1ms accu­ra­cy) as well as straight­for­ward PLC programming/automation accord­ing to IEC 61131–3 via the free iConf tool.

iGW-VM as Substation Gateway

Exam­ple schema of iGW-VM oper­at­ing as sub­sta­tion gate­way with hot-stand­by redun­dan­cy 

Technical Features

Hot-Standby Redundancy

In a hot-stand­by archi­tec­ture, the active iGW con­tin­u­ous­ly feeds the record­ed data to the redun­dant stand­by iGW to ensure that the new­ly active iGW has all the his­tor­i­cal infor­ma­tion (no data loss) when the switchover occurs.

If the active RTU detects that any IED is not able to com­mu­ni­cate, it tries to access the IED via the hot-stand­by RTU, which (in the case there was a con­nec­tion prob­lem) can pass the data to the active RTU, act­ing as a ser­i­al serv­er.

IEC61131‑3 PLC Automation

Thanks to its inter­nal PLC based on IEC 61131–3, the iRTU can pro­vide pow­er­ful automa­tion and con­trol func­tion­al­i­ties.
For exam­ple, you can eas­i­ly reuse pro­grams on dif­fer­ent projects, run mul­ti­ple PLC instances simul­ta­ne­ous­ly or use trig­gered vari­ables for con­trol com­mands and set points. It also allows to run hot pro­gram updates, stop PLC exe­cu­tions depend­ing on the qual­i­ty of select­ed PLC inputs and debug PLCs online, either cycle-by-cycle or step-by-step.

The iRTU has a high exe­cu­tion speed – a 2000 ST line pro­gram takes less than 3ms.

Cyber Security – IEC 62351

iGrid enforces sev­er­al lay­ers of secu­ri­ty mea­sures guid­ed by the propo­si­tions of the IEC 62531 stan­dard to pro­tect its devices from all kinds of threats.

The iGW-VM fea­tures 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.

IEC 61850 MMS

The iGWlite can be used as a sim­ple link between seri­al­ly con­nect­ed phys­i­cal devices and log­i­cal IEC 61850 devices as it can be sim­ply con­fig­ured to map any sig­nal from all sorts of data mod­els onto IEC 61850 log­i­cal nodes, whilst also pro­vid­ing IEEE1588 / PTP time syn­chro­niza­tion.

Thanks to its full iGrid pro­to­col stack, the iGWlite can con­vert any stan­dard or lega­cy pro­to­col such as IEC 60870–5‑103, SPAbus, Mod­bus, DLMS to IEC61850, mak­ing it com­pat­i­ble with hun­dreds of ven­dors.

Communication Protocols

The iGW was designed to use a high num­ber of pro­to­cols and com­mu­ni­cate with sev­er­al con­trol cen­ters at once.

The stack includes new­er pro­to­cols such as IEC 61850 MMS or GOOSE (A lev­el cer­ti­fied by DNV-KEMA), but also old­er stan­dard and pro­pri­etary pro­to­cols such as ModbusRTU/TCP, Profibus, SpaBus, Mlink or Pro­come. Oth­er sup­port­ed down­stream pro­to­cols for meters and pro­tec­tion relays are IEC 60870–5‑102/-103, IEC 62056–21 and DLMS, where­as upstream pro­to­cols for con­trol cen­ters also include IEC 60870–5‑101/-104 or DNP3.0 serial/TCP.

IP Networking

The iGW is equipped with trans­par­ent TCP bridg­ing and con­fig­urable IP rout­ing to tun­nel any ser­i­al pro­to­col (such as Mod­bus) over a TCP/IP con­nec­tion and facil­i­tate the data trans­fer through com­plex IP net­works.

Its VLAN and VPN sup­port allow to improve the network’s per­for­mance, sim­pli­fy­ing its traf­fic man­age­ment, design and deploy­ment and also help­ing to secure com­mu­ni­ca­tions through par­tic­u­lar­ly haz­ardous net­works.

iConf – One Configuration Tool for Everything

iGrid prod­ucts, includ­ing devices oper­at­ing with iGW-VM can all be local­ly and remote­ly con­fig­ured and main­tained via USB or Eth­er­net, using iGrid’s free iConf tool or stan­dard soft­ware tools such as tel­net. Alter­na­tive­ly, con­fig­u­ra­tion data can be up– or down­loaded via USB flash dri­ve, FTP man­ag­er or iConf.

We rec­om­mend using the iConf tool because it 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.

HV Smart City Maintenance System

In this project the iGW-VM com­mu­ni­cates with over 1 mil­lion I/O points from over 200 HV and 6000 MV sub­sta­tions to sign­f­i­cant­ly reduce the num­ber of inci­dents. The iGW speeds-up main­te­nance reac­tion times by inform­ing staff imme­di­ate­ly, regar­less of time and place, send­ing dai­ly reports and real-time data through the web.

Communication Front-End for Smart Metering Application
