结合某抽水蓄能电站机组现场试验,利用功率扰动下实测数据进行具有复杂输水系统的大型机组水力系统模型辨识.该辨识方法输入信号通过调整调速器给定功率获取,并不影响机组的正常试验和运行.使用增广最小二乘法进行辨识计算,利用先验知识检验、阶跃响应检验和残差白噪声检验三种方法对辨识结果进行验证.结果表明,所得辨识模型可信,利用功率扰动辨识水电站水力系统模型的方法可行.
- Abstract:
-
Combined with the field test of a pumped storage power station, the measured data under power disturbance were used to identify the hydraulic system model of large units with complex water transmission system. The input signal of the identification method is obtained by adjusting the given power of the governor, which does not affect the normal test and operation of the unit. The augmented least squares method was used to calculate the identification, and the identification results were verified by three methods: prior knowledge test, step response test and residual white noise test. The results show that the obtained identification model is credible, and the method of identifying the hydropower system model by using power disturbance is feasible.
