水轮机控制系统试验数据处理

Data Processing of Test Code of Hydraulic Turbines Control Systems

水轮机控制系统试验数据的真实性和可靠性是运行人员对水轮发电机组安全运行做出正确评估的重要依据。研究利用自适应的N点加权后置平滑滤波和自适应N点加权中间平滑滤波法对试验数据进行处理,并用处理前后的数据对公伯峡4号机电液随动系统进行参数辨识,取得了比较理想的效果,表明该方法能有效处理水轮机控制系统试验数据。

Data authenticity and reliability of hydraulic turbine control system tests are important bases for the correct assessment of safe operation of a hydro-generating unit. A research is done on the use of adaptive weighted point of postfiltering and adaptive point weighted smoothing filter in the middle of the trial data processing, and the use of data before and after processing for parameter identification in the Gongboxia 4th unit Electro-hydraulic servo system. Research result shows that the method can effectively deal with turbine control system test data.
