水布垭电厂机组全水头下稳定性分析

Stability Analysis of Turbine Units under All Possible Water Heads in Shuibuya Hydropower Station

以大量的PSTA2003状态监测及趋势分析系统的特征数据为基础,分析各机组在不同水头下的运行工况的特征表现,为电厂合理安排机组运行方式、确保机组在最优工况下运行提供了参考,还可通过对机组运行特征数据变化趋势的分析,及时掌握设备运行状态,及早发现设备隐患。

Based on the characteristic data collected from PSTA 2003 state monitoring and trend analysis system , the per-formance characteristics of each turbine unit in its operational conditions under different water heads are analyzed , which provides references for the proper arrangement of the unit operation mode so that the units can operate in their optimal operating conditions .In addition , with the analysis on the variation trend of the characteristic data of unit operation , the operating states of the units can be obtained in time and possible faults can be found quickly .
