Qinhuangdao Thermal Power Plant a total of 4 units, a total capacity of 1 000 MW, completed in two phases. The first and second units are Harbin-based 200 MW units, each of which is connected to the 220 kV bus in the substation. The 220 kV busbar is double-busbar bypassed and connected to the main system via two 220 kV lines. In normal operation, the power supply of the plant is supplied by the local high-voltage working transformer, and one unit of the 2 units is connected to the 220 kV bus
