Based on the analysis to the present situation and operation mode of Beilun grid in Ningbo , Zhe-jiang province, the paper investigates and demonstrates scheme for 600 MW units synchronized at 500 kV voltage class connects to 220 kV power grid and conductor section of outgoing transmission lines. According to the result, the implementation of 600 MW units in Beilun power plant changing to connect to 220 kV power grid can effectively improve the reliability of power grid , level of security and stability and the economic ben-efit of power grid operation.
