摘　　要：2007年2月26日广西电网平班水电厂调整运行方式在增加出力过程中发生低频振荡,为了找出抑制平班电厂机组与广西220 kV系统发生低频振荡的措施,决定对平班水电厂进行单机小扰动稳定性试验研究。通过确定研究内容、试验区域及仿真计算方法,在做好试验前的充分准备工作后,成功地完成了预定试验内容,并在试验过程中发现了今后运行可能存在的问题,找到了解决问题的方法。通过平班水电厂单机小扰动稳定性试验的研究,给日后采用新的运行方式提供了有力的依据。Low frequency oscillation occurs when the output increases in operation mode adjustment for Pingban Hydropower Station of Guangxi Power Grid on Feb. 26, 2007. In order to find out measures against such oscillation on the unit of Pingban Hydropower Station and Guangxi 220kV system, small disturbance stability test on single unit is done for the station. The test is completed successfully through determination of research content, test area and simulation calculation method. In addition, problems that likely arise in future operation and coun- termeasures are found in the test. The test is referential for the application of new operation mode in the future.
