iβref) is zero untilt= 0.1372 s. Therefore, theα-axis (andβ-axis) controller keepsuα(anduβ) equal toVsα(andVsβ). It means there is no voltage drop across the inductors and, thus,iα(andiβ) remains zero. Figure 11 also shows thatiαref (andiβref) is changed to a non...
Moreover, this article evaluates the controller performance in terms of maximum overshoot, steady-state error, settling time, rise time, and total harmonic distortion. It implements the proposed controllers in a typical VSC-HVDC system and multiterminal HVDC transmission syste...

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...
The proposed system is modelled and simulated in MATLAB using Simulink and power system blockset (PSB) toolboxes. Extensive simulation results are presented to demonstrate the capability of the controller as a harmonic eliminator, a load balancer, a neutral current compensator along with VF controller...
Using MATLAB–Simulink, the results significantly verify that the desired robust controllers based on SMC can achieve favorable tracking performance, and contribute efficiently towards improving the system's dynamic behavior, under either normal operating conditions or parametric uncertainties, for different ...
