摘要
随着高压直流输电系统的发展,多馈入直流系统逐步形成。对于多馈入直流系统,不止一个换流器联接到同一个交流母线,或者联接的交流母线非常接近。要准确地对多馈入直流系统的谐波特性进行分析,需要建立一个准确完善的稳态模型。采用Simulink建立了多馈入直流系统的仿真模型,并通过该模型对多馈入直流系统交、直流侧的谐波特性进行了分析。仿真结果表明,该仿真模型能够准确、直观地对多馈入直流系统的谐波特性进行分析。
The multi-infeed direct current （MIDC） system begins to form with the development of HVDC transmission system. In multi-infeed direct current system, there will be two or more converters connected to the same AC bus. or the nearby AC bus. To analyze the harmonic performance of the MIDC system accurately, a suitable steady model should be established. A simulation model of the MIDC system, which is used to analyze the harmonic characteristics of DC side and AC side of the MIDC system, is established with Simulink. The simulation results show that the harmonic performance of the MIDC system can bc analyzed accurately and visually with the simulation model.
