Abstract

The recent developments in power electronics technology have lead to the improvements of insulated gate bipolar transistor (IGBT) based Voltage source converter High voltage direct current (VSC HVDC) transmission systems. These are also commercially known as HVDC Light transmission systems, which are popular in renewable, micro grid, and electric power systems. Out of different pulse width modulation (PWM) schemes, Space vector PWM (SVPWM) control scheme finds growing importance in HVDC Light applications because of its better dc bus utilization. In this paper, SVPWM scheme is utilized to control the HVDC Light system in order to achieve better DC bus utilization, harmonic reduction, and for reduced power fluctuations. The simulations are carried out in the MATLAB/SIMULINK environment and the results are provided for steady state and dynamic conditions. Finally, the performance of SVPWM based vector controlled HVDC Light transmission system is compared with sinusoidal pulse width modulation (SPWM) based HVDC Light system in terms of output voltage and total harmonic distortion (THD).

平衡故障条件下基于SVPWM的矢量控制高压直流输电系统性能研究

近年来，电力电子技术的发展促进了基于绝缘栅双极晶体管(IGBT)的电压源变换器高压直流输电系统的改进。这些也被商业上称为HVDC光传输系统，在可再生能源、微电网和电力系统中很受欢迎。在不同的脉宽调制(PWM)方案中，空间矢量PWM (SVPWM)控制方案由于其更好的直流总线利用率而在高压直流照明应用中越来越受到重视。本文采用SVPWM方案对HVDC Light系统进行控制，以达到更好的直流母线利用率，降低谐波，减小功率波动的目的。在MATLAB/SIMULINK环境下进行了仿真，给出了稳态和动态条件下的仿真结果。最后，比较了基于SVPWM的矢量控制高压直流输电系统与基于正弦脉宽调制(SPWM)的高压直流输电系统在输出电压和总谐波失真(THD)方面的性能。
