| Abstract: | The time setting of reserve protection on the 110 kV side of 220 kV transformer necessarily leads to the variation of setting cooperation relationship of the entire 110 kV power network.In light of the power grid actualities in Huizhou,China,this paper presents a technical plan to harmonize the relay protection setting of 220 kV and 110 kV power networks,and puts forward some improving measures for the setting of microcomputer-based protection. |
