Abstract:

The domestic demand for electrical energy is increasing with the social and economic development.The expansion of the power system requires higher on its safe operation.The secondary circuit has an important role in guaranteeing the reliable operation of the power system and the quality of power supply.However,in the secondary circuit there are always hidden failures,which seriously affect the normal operation of the power system.On the basis of an introduction to the secondary circuit hidden failures,the impact of substation commissioning on the secondary circuit of hidden failures is analyzed and preventive measures and treatments of are given.

Key words: Substation Commissioning;secondary circuit;hidden failures
