水电站齿盘测频原理分析及优化应用

Analysis and Application Optimization of the Gear Plate Frequency Measurement Method in Hydropower Stations

依据水轮发电机组的齿盘测频方法和原理,针对某水电站在实际运行过程中遇到的转速测量信号跳变问题进行研究分析,采用了相应的改造措施,但其转速测量仍存在一定问题;为此对水轮发电机组转速测量方法做了进一步深入分析与优化探讨,使问题得到了有效的解决。

The working principles of the gear plate frequency measurement method for hydro-turbine generator units are introduced.Then,the signal jumping problem in the rotating speed measurement observed in a hydropower station is analyzed.Based on a detailed discussion of the measurement method,renovation and optimization measures are proposed and adopted.The signal jumping issue is thus fully solved.
