JSC “MOESK” (a Rosseti subsidiary) commenced design and survey works for construction of 110/20 kV “Medvedevskaya” substation. The substation is required to meet the growing power supply needs of the Skolkovo Innovation Center. Transformer capacity of the substation will be 2x80 MVA with potential increase up to 2x100 MVA.
The design works contractor is PJSC Stroytransgaz that is tasked with designing an innovative substation using the latest developments of modern power engineering, in particular digital and energy-saving technologies.
“Medvedevskaya” substation will be equipped with digital protective relay and automation devices for prompt detection of damaged elements and their separation from the electric power system as well as with digital instrumentation and switches. Digital equipment will be used for alarm events registration as well as registration and control of the electric power quality. Information exchange among all devices in the substation and the central server will be carried out via digital communication channels.
Digital data exchange will be carried out based on IEC 61850 standard (single protocol). Application of the protocol is a state-of-the-art practice for Russia providing a number of advantages. The format of the data received under the protocol from different equipment (regardless of the manufacturer, type, model and year of manufacture) will be absolutely identical. The protocol significantly facilitates integration of new equipment in the already existing complex electrical equipment system of the digital substation. Economic feasibility of using the materials: instead of a dozen of copper wires, only one wire is required under IEC-61850 protocol.
Due to the use of digital technologies, reliability of the substation improves significantly, capital costs of the materials (control cable) and its installation decrease as well as the cost of the substation operation.
It is also planned to use energy-saving technologies. The heat generated by transformers of the substation will be used for heating the power supply center.
The electric energy for lighting the substation will be generated using a photogalvanic technology that allows for direct conversion of the solar energy reaching the surface of the Earth into electric energy.
The design and survey works completion is scheduled for December 2015.
