Sažetak
This paper presents simulation of de-energization of 100 Mvar shunt reactor in transformer station 400/110 kV Ernestinovo in Croatia. The shunt reactor is normally disconnected at periods of heavy loads and is connected during periods of low loads. Transformer station Ernestinovo is a key point of connection between UCTE 1 and UCTE 2 zone and the purpose of this shunt reactor is to regulate the reactive power balance compensating the reactive power generated by 400 kV transmission lines at periods of low loads. During the process of shunt reactor de-energization, dangerously high over voltages can appear. Simulation of shunt reactor de-energization is performed using ATP-EMTP software. All components necessary for the simulation as shunt reactor, transformers, busbars, circuit breakers, transmission line, surge arrester and equivalent Thevenin symmetrical source of 400 kV utility are modelled using ATP-EMTP software. Simulation of shunt reactor de-energization is analysed for several cases when surge arrester is not connected on shunt reactor busbars and without using synchronous controllers of reactor circuit breaker when surge arrester is connected on shunt reactor busbars and without using synchronous controllers of reactor circuit breaker when surge arrester is connected on shunt reactor busbars and reactor circuit breaker are controlled using synchronous controllers.
