Pursuant to the contract of relay protection and automatic equipment microprocessor devices 500kV Rakurs Group has shipped 26 cabinets for Zagorskaya HPSPP-2 in spring 2012. This supply being a part of Zagorskaya HPSPP-2 automation complex project realized by SPC Rakurs includes the following:
· Modernization of electrotechnical equipment automated control system: relay protection and automatic equipment, switchgear and control gear 500kV;
· Automated control system equipment · supply for station junction;
· Reconstruction of starting tiristor device power part and control system; contract supervision, personnel training.
This project is a result of successful and effective cooperation with Zagorskaya HPSPP-2 in 2006-2011 including modernization of automated control systems for hydro units 1-6 of Zagorskaya HPSPP (RusHydro OJSC Branch). Having been selected as contractor for projecting, manufacturing, assembly, start-up and adjustment of Zagorskaya HPSPP hydro units automated control system SPC Rakurs made its début in HPSPP complex automation projects. It was also a significant event in the sector as there had been no companies in Russia realizing such complex projects for HPSPP. It was a transfer to a new level of equipment control for the Plant providing extra possibilities for creative work approach in the future.
The complex of switchgear and control gear relay protection and automatic equipment has been designed with the use of Siprotec microprocessor terminals of Siemens manufacturing.
The main functions of the equipment include the following:
· relay protection and automatic equipment of Zagorskaya HPSPP-2 high-voltage lines 500kV, Trubino No.2, Yartsevo No. 1, Yartsevo No. 2.
· relay protection and automatic equipment of switchgear and control gear buses, Zagorskaya HPSPP-2 500kV
· relay protection and automatic equipment of Zagorskaya HPSPP-2 units No. 3 and 4 bus arrangement.
