龙口水电站调速器电气控制系统改造

Reformation of electrical control system for speed governor in Longkou Hydropower Station

针对龙口水电站调速器电气控制系统部分模件故障率不断增加、备品备件采购困难、备用通道不足、操作维护不便等问题,经分析、设计、选型,在原有WDST型式基础上,采取控制器升级、电液转换器换型、导桨叶传感器换型、通信结构优化等措施对系统进行了改造。新改造的系统经静态、动态试验验证,运行稳定、可靠,各项功能符合现行规程要求,且操作维护方便,解决了原系统存在的问题,获得了预期的效果。

The failure rate of some modules in speed governor electrical control system of Longkou Hydropower Station is increased constantly,it is difficult to procure spare parts,the standby channels are insufficient,and the maintenance operation is inconvenient,etc.The following measures are adopted to reconstruct the system aiming at the above-mentioned problems through analysis,design and model selection on the basis of original WDST model.The newly reconstructed system is verified through static and dynamic tests.It is operated stably and reliably.All functions are consistent with existing regulations and requirements.The system is operated and maintained conveniently.Problems in the original system is solved,and expected effects are obtained.
