摘要
叙述了三峡左岸电站主要发输电设备投产以来的运行情况,对运行可靠性数据进行了分析。针对运行中出现的问题(如发电机纯水系统频繁故障、VGS公司机组水导轴承油槽漏油及水导轴承冷却器泄漏、Alstom机组活动导叶下沉、导流板撕裂等),三峡水力发电厂采取了的一系列技术稳定措施(如安装电力系统稳定器和安全稳定控制装置等),从而极大地提高了发输电设备运行的稳定性、运行效率和安全可靠性。如强迫停运率从2003年的0.5%分别提高到2004年、2005年的0.05%、0.10%;总体评价得分率达88.5%。
The operation conditions of major power generation and transmission equipment in Three - Gorge Left Bank Power Station were narrated, and the operation reliability data were analyzed. According to the problems appeared in operation, such as frequently faults in generator pure water system, oil leakage of the bearing in VGS company＇ s unit, sinking of the guide vane and tearing of the flow guide etc. in ALSTOM unit, a series of technical stability measures was adopted in Three - Gorge Hydropower Plant, such as installation of power system stabilizer and safe and steady control equipment etc., which extremely improved the stability, operation efficiency and reliability for power generation and transmission equipment operation. The forcing outage rate was raised from the 0.5% in 2003, to the 0.05% and the 0.10% in 2004 and 2005 respectively. The overan appraisement score reached 88.5%.
