岩滩电厂机组强迫补气自动控制系统应用研究

Study about the Application of Automatic Control System to Supply Carrier Gas into Generators in Yan Tan Hydraulic Power Plant

岩滩 30 0 MW机组的振动 ,经数年多次研究及分析 ,就减振措施而言 ,对机组进行补气是一个十分有效的方法。为此进行国内首次机组强迫补气自动控制系统的应用研究 ,结合现场机组振动测试 ,及自动控制系统本身的采集测量结果 ,以提高测量控制准确度为目标 ,分析、优化程序并对系统参数进行了整定。现场使用证明控制系统可正确地在机组运行的强振区域自动投运。

After study and analysis through years, as far as the solution to reduce vibration on 300 MW generators in Yan Tan hydraulic power plant is concerned, it is effective to supply carrier gas into generators Then the automatic control system to supply carrier gas is studied first time domestically According to the results from the field vibration test and the signals from the automatic control system, the procedure is analyzed and optimized and parameters of the system are adjusted in order to improve the measuring accuracy The field operation shows that this system works properly and automatically during strong vibration on generators \ \
