泵站异步机组电容补偿装置运行工况分析

An Analysis of Operation Conditions of Capacity CompensatingInstallation of Asynchronous Machine Unit in Pumping Station

对泵站异步机组、单机补偿装置手动切换、取消拍门和底阀运行中可能出现的过电压、电流冲击及机组振动等问题进行分析，指出问题的严重性，并在机组保护接线中采取相应措施，保证泵站机组安全运行。

This paper analyses the possible occurence of the problems concerningover-voltage,current shock and machine unit vibration in the operation process of ayn-chronous machine unit, manual overswitch of unit machinery compensating installation,discarding beat gate and bottom valve in pumping station.Also ,this paper points outthe serious problem is to adopt the corresponding measures in protectiveling connectionin machine unit so as to ensure safety operation of the pumping station.
