During the operation of the hydro generator in Taipingwan Hydropower Station,the cooling water filter was blocked by low-density floating or suspended particles frequently,which had led to force the unit into shutdown.Analysis of blocking cause revealed that the original design of the cooling water filter did not consider the discharge of low-density impurity.The blowdown outlet of the cooling water filter is connected to the leakage well of the plant through underground pipeline.The underground pipeline is long,and was designed with no consideration for clearing blockage.To address this,revamp was made to the cooling water filter of the hydro generator and the blowdown pipe.After multiple technical assessments by technician,updating the cooling water filter can effectively filter and discharge floating or suspended particles in the wastewater.Simultaneously,revamp was made to the blowdown pipe to enhance the blowdown efficiency of the cooling water filter.
