The Khovanskaya substation became the largest digital and power supply center in New Moscow. Its installed capacity is 700 MVA. The substation was built in 18 months, and now it can lessen the load on old power supply centers and connect new power consumers.
The substation equipment is entirely Russian-made, and some of it is manufactured PLC Technology. PLC Technology implemented its own solutions based on the TOPAZ Software and Hardware System (SHS). The facility features digital technologies that comply with the IEC 61850 standard.
PLC Technology implemented the following systems:
APCS at the Khovanskaya 220 kV substation enables complex process automation to raise the reliability and efficiency of the substation equipment and adjacent electrical networks. This will provide reliable power supply to the consumers, reduce operating costs, minimize the substation staff and increase their safety.
The telemechanics system at the substation is designed to collect and transmit information on the 220, 110 and 20 kV network operating modes, the state of the substation electrical circuit, process equipment at the Network Control Center of PJSC MOESK, New Moscow DC of PJSC MOESK branch, DC of SO UPS JSC branch, and Moscow Regional Dispatching Administration.
A complete proprietory hardware and software system to implement DSS: AMU and DMU devices, network switches, time synchronization devices, universal computing modules with various processing speeds (controllers, servers, IEDs), as well as relay protection and automation, APCS, power quality monitoring, disturbance recording, power metering algorythms, etc.
The main Khovanskaya 220/110/20/10 kV substation equipment based on the TOPAZ SHS:
• APCS cabinets;
• Personnel automated workstations;
• Power-system protection automated workstation;
• TOPAZ modules: data access servers, time servers, switches, routers;
• Metering modules;
• Power and telemechanics modules;
• Process bus couplers
The new Khovanskaya 220/110/20/10 kV substation was commissioned on October 16, 2019. The launch was attended by the Russian Minister of Energy Alexander Novak, the Moscow Mayor Sergey Sobyanin and Director General of Rosseti PJSC Pavel Livinsky.
