拔贡水电站辅机控制的轴承供油泵控制PLC程序的改进

摘要

By analyzing the unconformity between the initial design of the auxiliary control process of the Bagong hy-dropower station and the spot situation during practical application, the auxiliary control process and the PLC program are improved mainly by modifying the PLC program control process of the bearing oil feed pump, which ensures the safety, reliability and stability of long-term operation of the units.%通过分析拔贡水电站的辅机控制流程的原设计，在实际运行中出现的不符合现场实际情况的问题，结合现场实际情况，进行辅机控制的流程和PLC程序改进，主要通过更改轴承供油泵的PLC程序控制流程，使改进后的辅机控制更加适合现场实际，保证机组长期运行的安全性、可靠性、稳定性。
