JSC MOESK
2014-2018 гг.
2х80 MVA
transformer capacity
In December 2014, PJSC “Stroytransgaz” (STG) was awarded by Moscow United Electric Grid Company (MOESK) the tender for design and surveys for the construction of the 110/20kV Medvedevskaya substation (SS).
The substation is intended to meet the growing power needs of the Skolkovo Innovation Centre. The substation’s transformer capacity will be 2х80 MVA which can be increased to 2х100 MVA.
The project provides for STG to design a digital substation (DSS) equipped with digital relay protection and emergency control automatics to promptly detect damaged elements and cut them off from the power grid, with digital instrumentation and circuit breakers. Accident recording and electricity quality control will be carried out using digital equipment. All the substation’s devices will exchange information among themselves and with a power facility’s central server via digital communication channels.
Digital data exchange at the substation will be done using IEC 61850 protocol (uniform standard). Use of the protocol is Russia’s latest practice offering a number of advantages. The data received via the protocol from various equipment (irrespective of the manufacturer, model and year of manufacture) will be in absolutely identical format. The protocol makes it considerably easier to incorporate new equipment into the existing complex CGP electric equipment system. Material efficiency: under IEC 61850 protocol, use can be made of only one copper wire instead of ten.
Digital technologies will dramatically enhance the substation’s performance reliability, reduce capital outlays for materials (control cable), installation and use of the facility.
STG intends to apply energy saving technologies. Heat released by the substation transformers will be used to heat CGP. Electricity for the substation lighting will be generated by a photocell technology allowing the solar power received by the earth surface to be converted into electricity.
The substation construction commenced in October, 2016 and completed in May, 2018.
