Abstract


Xingtai grid grid small power plants run several unsafe , resulting in a the 110kV substation full stop , affecting the reliable power supply . To effectively curb insecurity , improve customer service reliability , and to ensure the safe operation of power grids , run to the Xingtai power grid relay protection and automatic safety device configuration and tuning research has important practical value and a certain academic significance . This thesis describes not consider small power plants and network protection configuration and tuning programs, research grid short-circuit current with a small power grid running Xingtai a local power grid in a different point of failure failure distribution , analysis and small network system of the plant , especially the impact of relay protection and automatic device configuration and tuning to the Bao Dai grid security run target , perfect 110kV local relay protection and automatic device configuration program and its tuning principles ; proposed to improve the reliability of power supply of the important users , the distant breaker remote cut program .
