The Analysis And Control Of The Electromagnetically Coupled Power Loop

The electromagnetically coupled power loop is a particular form of network configuration in the development of Power Grid. With the development of 750kV and ultra-high voltage Power Grid in China, The electromagnetic loop circuits appear in many places. For the reactive circular power flow in looped operation of looped electromagnetically coupled power network, its procreant mechanism and control strategy are analyzed and the research results are applied in the control of reactive circular power flow in looped electromagnetically coupled 330 kV and 220 kV power network from Liujiaxia to Bingling in Northwest China power grid. This paper theoretically introduces the control mechanism of electromagnetically coupled power loop, and analysis the procreant mechanism and control strategy of reactive power circulation in electromagnetically coupled power loop.In this papers,the judgment standard for decoupling decision of the electromagnetic loop is designed, And applys the theoretical conclusions to the project of Discuss And Compile The Power Grid Operation Modes Of The 750kV Electromagnetically Coupled Power Loop. It's hopeful that the research is useful to the security and economy of the coming looped electromagnetically coupled power networks of 750/330 kV power grid in China.
