Belarus, Minsk: The second 330 kV shunt reactor of the Belarusian nuclear power plant has been commissioned, the press service of the Belarusian national electric company Belenergo said.
According to the source, overhead power lines with the nominal voltage of 330 kV represent one of the main sources of reactive power. This is why they affect voltage levels in the country’s power grid.
The first 180 MVAr (mega volt-ampere reactive) shunt reactor of the Belarusian nuclear power plant was commissioned in December 2018 to allow the connection and operation of four 330 kV overhead power lines. They connect the Belarusian nuclear power plant with the power substations Smorgon, Minsk North, Postavy No. 1 and Postavy No. 2.
The second shunt reactor was tested and commissioned on 29 March 2020. Thus, the 330 kV switchgear of the Belarusian nuclear power plant is ready for connection of the other three 330 kV power lines. Those will connect the Belarusian nuclear power plant with the power substations Stolbtsy, Molodechno, and Ross.
At present, the Belarusian power grid uses five 330 kV 180 MVAr controlled shunt reactors (two at the Belarusian nuclear power plant, one at each of the 330 kV power substations Postavy, Baranovichi, and Miradino), two 750 kV 330 MVAr shunt reactors at the 750 kV power substation Belorusskaya, and six 10 kV low-yield shunt reactors (20-30MVAr) at the 330 kV power substations Smorgon, Lida, Kaliynaya, and Mozyr.
A 180 MVAr controlled shunt reactor may be installed at the 330 kV power substation Ross in the future. Two small shunt reactors may be installed at the 330 kV power substations Stolbtsy and Mikashevichi.
