摘　　要：为提高PSD-BPA暂态程序中水轮机仿真模型的仿真精度,给电力系统稳定计算提供更加精确的机组仿真模型,以水轮机线性化模型为基准,分析水轮机仿真模型仿真结果与实际相差较大的原因,并对模型进行改进,在水轮机力矩对开度传递系数处添加机组出力P与导叶开度Y的关系曲线模块(简称出力–开度模块),并在模型中添加偏差求取模块,形成改进的水轮机模型。对模型进行验证,仿真结果与实测曲线吻合度高,实时验证模型仿真结果是否符合标准,可大大提高水轮机仿真模型的仿真精度。In order to improve simulation precision of hydroturbine simulation model in PSD-BPA transient program and provide more precise simulation model for stability calculation for the power system, this paper takes linear model for hydroturbine as the standard for analyzes reasons for large differences between simulation result and actual situation. It has improved the model by adding relationship curve module called output-opening module of turbine output and guide vane opening, and adding deviation calculating module in the model. It carries out verification for the model and obtains simulation result which is highly identical to actual measured curve. It is able to greatly improve simulation precision of the model by real-timely verifying whether the simulation result is satisfied for standard.
