【摘要】 钢铁变电所供电负荷为五台制氧机,供电电网系统中还包括发电机组等负荷,其继电保护计算极为复杂,在同类型的110kV等级变电所设计中具有典型性;通过对该变电所继电保护中短路电流的计算与分析,确定了变电所的一次运行方式,为变电所的正常运行提供了可靠依据,为今后同类型变电所设计提供参考依据。更多还原

【Abstract】 The power loads of our iron&steel substation include 5 oxygen plants,meanwhile,the power system has also other loads,such as generators,therefore,the calculation of its relay protection is extremely complicated,being typical for the design of 110 kV substations of same type.The paper calculates and analyzes short-circuit current in the relay protection of the substion,decides the primary operation of the substation and provides a reliable basis for its normal operation.It provides a reference for the design of substations of same type in the future.更多还原
