| Abstract: | With the further expansion of the power network,220 kV network becomes the main power grid network.It occurs that two tripping circuit cannot act due to the first control power failure in 220 kV and higher voltage level networks with double protection.It is analyzed and the measure for improvement is given.The results show that the schemes can meet the requirements of equipment operation and guarantee the operation reliability of power system and power supply of pressure locking circuit. |
