摘　　要：叙述了用于电力系统分析的紧水滩水轮机调速系统建模的技术思路,采用阶跃法进行调速系统分部试验、建模和总体校核,完成了满足各水头和工况的规范化线性和非线性水力系统下的调速系统模型参数的建立,提出了用于模型参数检验定量判断的响应面积误差法,并与一次调频要求进行比较,证明所提供的紧水滩水轮机调速系统模型参数满足工程应用要求。The modeling method of the hydro-turbine governor system of the Jinshuitan hydro-turbine generator for electric power system analysis is presented. By use of the step response method, both linear model and nonlinear models of hydroturbine governor system under different operating conditions are established. In order to verify the provided models, the response area error method is proposed. Furthermore, simulation results are compared with the demand of first time frequency modulation and it is proved that the p＇rovided models of hydro-turbine governor system satisfy the demand of practical projects.
