Digital Simulation Researches on Dynamic Capability of Multi-section Circular Arc Limited Waterwheel Generator

考虑电网的影响,研究多段圆弧极靴水轮发电机在各种非正常工况下,其动态性能数字仿真的数学模型和计算方法。主要从电路的方面,采用直接相量法建立通用模型。在建模过程中重点解决转速变化、铁磁材料饱和等非线性因素对参数的影响。引入全变量法用于电机动态仿真计算,采用预估-校正法使机、电方程解耦。

Considering the effect of a electrified wire netting, in all unnormal work, the mathematical models and computational methods of dynamic capability of the multisection circular arc limited waterwheel generator are studied, which uses direct vector methods to set up general methods by circuit.In seting up models, the effect of changing rotational speed and saturating magnetical materials. nonlinear factor on the parameter are solved. The paper also gives an account of its all variable method for dynamic simulation compution of the generator and method of prophecy check to solve machine and electric equation.
