摘要
引入时变动态相量法对高压直流系统建模,可以直接从系统时域微分方程建立相应的动态相量模型.通过截取相关变量对应的时变傅立叶级数的重要项对系统模型进行简化,从而达到提高仿真速度的目的.通过对一个简单的HVDC-VSC(电压源换流)系统建模,介绍了时变动态相量法的建模过程,最后给出了具体的算例.证明了时变动态相量法在电力系统建模中是精确而有效的.
A newly developed method-dynamic phase method is presented. Dynamic phase models can be obtained directly, which is a state-space models from the differential equation. Using the method, much time of emulation can be saved. Through typical test examples of HVDC-VSC system and their emulation result, the process of dynamic phase models is introduced and the effectiveness and accuracy of this model are verified.
