摘要
汽机原动机的高、中、低压缸以及再热器的时间常数和油动机的开启及关闭方向的时间常数是汽轮机及其调速系统模型参数辨识的重点。因此,围绕模型参数的获取,介绍了现场测试这些参数的方法。并通过分宜电厂8号机实际测试实例,较系统地阐述了如何根据现场实测结果,得出稳定计算用模型参数。
In order to identify the parameters of steam turbine and its speed governor system, it is important to know the time constant of high, intermediate and low pressure cylinder of prime mover, the time constant of reheater and that of oil engine direction, open and closed. Test methods for the parameters were introduced and practical test were performed. According to the result, the model parameter for stability computation of NO.8 unit of Fenyi Power Plant was put forward.
