水轮发电机组盘车数据处理及软件开发

Data processing and software development for the jigger of hydroelectric generating set

盘车是立式水轮发电机组安装检修过程中一项十分重要的工作,良好的盘车质量是机组健康运行的重要保证。传统的人工等角测量方法,劳动强度大,工作效率低下,而自动盘车方法不能从根本上提高盘车速度及工艺。本文采用非线性函数拟合方法进行盘车数据处理,提出了一种综合考虑法兰处摆度和水导处摆度的刮垫厚度和最大摆度方位计算方法,并开发了相应的盘车数据处理工具软件。实际应用表明,该方法应用方便,加快了盘车速度,提高了盘车质量。

Jigger is an important process during the installation and overhaul of vertical hydrogenerator.The good quality of jigger is an important insurance for the safe operation of the unit.The traditional method,artificial isogonism measurement,has large workload and low efficiency.At the same time,the artificial jigger method cannot improve the speed and technique radically.The present paper adopts the nonlinear function approximation method and develops corresponding software for the jigger data analysis.The practical application results show that the method has high convenience and speed,which improves the quality of jigger.
