description: The subject of the graduate qualification work is Â« The electrical part of a high-pressure hydroelectric power station on the Angara River. Investigation of ways to compensate for non-simmetry of currents and voltages in the auxiliary system of hydroelectric power plantsÂ». The paper discusses the design of a hydroelectric power station, the prototype of which was the Boguchanskaya hydroelectric power station, which is part of the Angarsk cascade of the UPS of Siberia. Based on the location and specifics of the given station, the main electrical power equipment is selected. Also, according to the industry standard of PJSC RusHydro [9] and PUE [10], GIS schemes were selected. Based on the results of calculations of short-circuit currents, switching devices, conductive part and measuring devices were selected for metering and monitoring the quality of electricity. Thus, taking into account the studied unfavorable seismic features of the terrain, GIS 220 kV ELK-14 and GIS 500 kV ELK-3 manufactured by ABB were selected for high voltage, for generator voltage - EGRU HEC-7B and KRU serias Â«VolgaÂ» for their own needs. When choosing cables, preference was given to cables with XLPE insulation (PvPu). This is due to numerous advantages: high operational reliability, resistance to temperature extremes due to the climatic characteristics of the zone, high throughput, etc. The paper provides an overview of methods for compensating for asymmetry in electrical networks and investigates a method using a balancing device. To study this problem in Simulink software has developed a computational model with an asymmetric load powered from the buses of common auxiliaries of the projected HPP. The calculation results showed that the negative sequence component decreased significantly after the bazooka was inserted. In addition, the zero-sequence asymmetry coefficient also decreased, which indicates a positive effect from the use of the studied compensation method.
