| 摘 要： | 综合电力系统（integrated power system,IPS）包含3/12相双绕组发电机等特殊高阶非线性元件,现有电力系统电磁暂态仿真软件均不提供其仿真模型。为此,采用隐式梯形法对双绕组发电机数学模型进行差分离散化处理,通过定、转子分离迭代,推导出电机等效电路模型,并在PSCAD中建立双绕组发电机仿真模型。应用时步保持算法,将模型的仿真时步划分为计算时步和保持时步,提高了计算速度。最后,构建综合电力推进系统试验平台,发电机空载短路、推进系统调速的试验与仿真结果吻合,验证了建模方法的有效性和所建模型的正确性。研究表明,基于隐式梯形–时步保持算法的建模方法能够准确高效地建立双绕组发电机的仿真模型,可应用于EMTP类仿真软件,并可推广至IPS各类多相电机建模。

| Abstract: | The integrated power system(IPS) contains special,high-order and non-linear components like 3/12-phase double winding generators.These components' simulation models are not offered by any power system electromagnetic transient simulation software.To model the double winding generators,the implicit trapezoidal method was applied to transfer the double winding generator's mathematical model into difference equations.By using the stator-rotor-separate iteration method,the generator's equivalent circuit model w... |
