-
摘要: 本文介绍了在某水电站发电机组处于不同运行方式下在线辨识的试验结果,试验结果表 明,应用伪随机信号相关仪在电力系统中进行在线辨识是安全可行的,并且看出单台发电机组 的动态特性与电力系统的结构和潮流有关.Abstract: This paper deals with the on-line identification test of a generator dynamies in a hydroelectric power station at different operating modes. The results of the test show that application of the PRBS-correlator for on-line identification in a power system is safe and suitable, and that the dynamics of single generator is related to the structure of the power system and load flow within the system.
