| 摘 要： | 为了得到轻型高压直流输电(VSC-HVDC)系统的稳态和动态特性,在探讨轻型高压直流输电的原理并简介VSC - HVDC常用三种控制策略的基础上,针对定直流电压和定有功功率的控制方式,利用MATLAB软件中的Simulink模块建立仿真模型,仿真分析了VSC - HVDC的稳态特性,再对几种常见的交流侧物理量扰动和三相短路故障进行仿真,得出相应的动态特性仿真波形.仿真结果表明了仿真模型的正确性和有效性,可为VSC-HVDC系统的参数辨识、控制和故障诊断提供参考.

| Abstract: | In this paper,for getting the stable and dynamic characteristic of VSC-HVDC,the theory of VSC-HVDC has been analyzed.Three controlling methods of VSC-HVDC have been introduced.Modeling and Simulations based on Simulink have been used to analyzed the stability of VSC-HVDC which using the fixed DC voltage and fixed active power flow controlling method.Through simulating the three-phase-fault and several commonly disturbances in AC system,the waves of dynamic characteristic of VSC-HVDC are gotten.The result of the simulation verifies the correctness and rationality of the established simulation model.This study provides a reference for parameter recognition,controlling and fault diagnosis of the VSC-HVDC. |
