随着国内水电机组状态在线监测系统在三峡左岸电站、右岸电站、紫坪铺电站、拉西瓦电站等一批大型水电机组的成功应用,该系统取得了良好的效果,为保障大型水电机组的安全、稳定运行发挥着重要的作用。本文介绍了锦屏水电站机组状态在线监测系统的组成、常用监测与分析工具,分析了该系统在投产初期的不足,阐述了锦屏水电站开展机组状态在线监测系统的现实意义。 With the successful application of domestic on-line monitoring system of hydropower unit status in a large number of large hydropower units such as the Three Gorges Left Bank Power Station, Right Bank Power Station, Zipingpu Power Station and Laxiwa Power Station, the system has achieved good results. In order to protect large-scale hydropower units Safe and stable operation plays an important role. This paper introduces the composition of the on-line monitoring system of the unit status of Jinping hydropower station, the common monitoring and analysis tools, analyzes the shortcomings of the system in its initial operation, and expounds the practical significance of Jinping Hydropower Station on-line monitoring system of unit status.
