摘　　要：发电机励磁控制系统对电力系统的静态稳定、动态稳定和暂态稳定特性都有显著影响,在电力系统稳定计算中采用正确的励磁系统模型和参数对稳定计算结果至关重要。励磁系统参数众多,包括励磁机时间常数、励磁系统总的静态增益、PID环节时间常数、发电机励磁绕组定子开路时间常数等。本文以湖北省某三机励磁系统为例,分析了以上参数对发电机组暂态特性的影响,可为存在类似情况的励磁系统模型参数校核和参数优化提供参考。The excitation control system of generator has significant effect on the static stability,dynamic stability and transient stability of the power system.In power system stability calculation,using correct excitation system model and parameters is very important.Excitation system parameters are numerous,such as the excitation time constant,the static gain of the excitation system,the PID time constant,the open circuit time constant of the generator excitation windings,etc.The influence of the above parameters on the transient characteristics of the generator set is studied in the case of a three machine system in Hubei province.The research results will provide reference for the optimal of the parameters of the excitation system model.
