基于DSATools的发电机及其控制系统模型参数仿真方法

精确的发电机系统参数是电力系统分析的基础。很多情况下由于工况条件限制无法对发电机参数进行准确的测量，给系统的安全校核、指标估计及潮流优化等工作带来较大困难。提出了一种基于仿真模型进行参数辨识的方法，通过DSATools仿真工具搭建发电机及其控制系统仿真模型，采用曲线拟合的方法进行参数优化得到了准确的仿真结果。以广西平班水电厂发电机组的发电机及其控制系统作为算例，验证了仿真模型参数辨识的可行性。

Parameter Simulation Methods for Generator and Its Control System Based on DSATools Simulation Tools

The knowledge of accurate parameters of the generators and their control systems is the basis for power system analysis. Exact on-line parameter identification is usually difficult to realize due to the limit of working conditions, this brings difficulty to the security check, index estimation, flow optimization and other works of the power system. A parameter recognition method based on the simulation model was presented in this paper. The simulation model of a generator and its control system was built with the DSATools, parameters were optimized by measures of curve fitting, and then the exact parameters simulation results can be gained. Finally, the generator and its control system of Pingban hydropower generator units were tested as an example, which confirmed the feasibility of parameter recognition with the simulation model.
