摘要

运用一种新的建模方法——基于时变傅里叶级数的动态相量法对基于电压源换流器的高压直流输电(VSCHVDC)系统进行建模分析。在系统开关函数模型的基础上

该方法通过忽略系统动态方程中状态变量所对应的时变傅里叶级数中那些不重要的高次项而对原系统进行简化

从而得到系统的动态相量模型及其方程。结果表明

动态相量法模型仿真相当于详细时域模型仿真结果的包络线

而且可以极大地减少系统的仿真时间

可以作为电磁暂态和机电暂态模型的接口

应用于电力系统的混合仿真。

Abstract

Based on the timevarying Fourier coefficient series

a newly developed method—dynamic phasors method is presented and applied to model and analyze VSCHVDC (voltage source converter based HVDC). On the basis of the system switch function model

this approach makes the system simple by neglecting the unimportant higher order components and keeping only those significant components of the Fourier series corresponding to the state variables in the system dynamic equations

so the system dynamic phasors model and equation can be gained. The results show that the dynamic phasors method simulation corresponds to the envelop of the detailed time domain simulation and can reduce the system simulation time greatly. The dynamic phasors method can become the interface of the electromagnetic transient and electromechanical transient models and is applied to the hybrid simulation of power system.
