FACTS devices can be used for the following purposes:

• increasing grid transmission volume;
• ensuring operational stability of electric power systems in case of various disturbances;
• maintaining distribution schemes with preset capacity levels within the grid per the dispatcher’s instructions;
• increasing reliability of end users’ energy savings;
• reducing electric grid losses;
• transforming the grid from a passive vehicle for power conveyance to an active operations control function.

RDCPE offers a range of services for installation and commissioning of FACTS devices and related technologies.

• controlled shunting bus and feed reactors rated for 110-500 kV;
• static compensators of reactive power (thyristor or STC) or fully programmable semiconductor-based (STATCOM);
• phase shifting devices (PSD);
• programmable serial compensator devices (PSCD);
• integral capacity flow regulators (ICFR)
• electric machine compensators of reactive power and phase shifting devices, including asynchronized machines such as asynchronized turbine generators, asynchronized compensators, asynchronized frequency converters, etc.

Unified National Energy System (UES) facilities with installed and commissioned FACTS devices:

• 500 kV substation at Novo-Anzherskaya, Siberia Energy Systems – STC-2 ± 100 MVAp, 11 kV – primary STC example, commissioned in 2004. The device was able to stabilize voltage and reduce var flows as well as lighten the load on backbone autotransformers of Kuzbass Trunk Grid Operator;
• 330 kV substation at Sovetsk, Northwest energy systems: controlled shunting reactor of 25 MVAr, 121 kV – a magnetically controlled shunting reactor commissioned in 2003. The device ensured automatic stabilization of voltage at substation busbars and in the adjacent network;
• 500 kV substation, Khabarovsk, Eastern energy systems – controlled shunting reactor of 100 MVAr, 242 kV – commissioned in 2004. Ensured automatic voltage stabilization at substation busbars and in the adjacent network;
• Generator unit #3, thermal power plant #27 of Mosenergo JSC – asynchronized turbine generator, 160 MVt, 15.75 kV with controlled winding – commissioned in 2007 as part of CCGT unit – 450 T. The device optimized plant capacity, improved reliability of end user power supply, reduced the load of backbone network autotransformers of 500 and 220 kV, and stabilized U-levels of the 220 kV network;
• Vacuum-reactor units at 4 330/110/10 kV substations at Northwest energy systems:
  
  
  • 330 kV Staraya Russa substation (Tverenergo)
  • 330 kV Novo-Sokolniki substation (Tverenergo)
  • 330 kV Sovetsk substation (Yantarenergo);
  • 330 kV Velikoretskaa substation (Tverenergo).
• Vacuum-reactor units at 2 500 kV substations in the Eastern and Central energy systems:
  o 50 MVAr, 11 kV STATCOM at 330/400 kV substation Vyborgskaya – commissioned in 2008. STATCOM was assembled and tested at RDCPE’s facilities. The company is currently preparing to ship the unit to the worksite and implement system testing.
  
  The intended impact is to improve inverter stability; gradually replace synchronized compensators, stabilize voltage, and cover the shortage of reactive power after one of synchronized compensators is decommissioned for repairs.
  
  Note: should the operation of the 1st STATCOM prototype turn out to be favorable, consideration will be given to replacement of 100 MVA and 160 MVA synchronized compensators;
• 2 100 MVAr asynchronized compensators with controlled winding at Beskudnikovo substation. The task order has been finalized, and production has begun for the 2 reactive power asynchronized compensators of as part of the comprehensive substation upgrade.
  
  The intended effect is to replace synchronized compensators in order to improve 500 kV network stability in the dynamic, transitional and post-accident operations mode.
