摘要:
Abstract—This article describes generic high level control models for VSC-HVDC grid systems. An average value model of the voltage source converter (VSC) is used; it includes the vector current control strategy. As an improvement to traditional conventional high-level control systems, this paper includes dc voltage, negative sequence current and dc voltage droop control loops. To validate the controller’s performances, two tests systems were developed: a point-to-point link and a four-terminal DC grid. Both offline and real-time simulations are carried out for several test scenarios. A methodology for calibrating controller parameters is presented and used to tune the controls of each test system considering the different scenarios presented. All simulation models were developed in SimPowerSystem/Simulink and prepared using the RT-LAB software from Opal-RT for real-time simulation; real-time simulation performance of the simulation models is also discussed.

摘要：这篇文章介绍了VSC-HVDC电网系统的通用高电平控制模型。文中用到了电压源换流器（VSC）的平均值模型；它包含矢量电流控制策略。作为对传统高电平控制系统的改进，这篇文章包含了直流电压，副序电流和直流电压垂降控制环。为验证控制器性能开发了两套测试系统：y一个点对点连接和一个四端点直流电网。针对数个测试方案进行了离线和实时仿真。文章提出了一种控制器校准参数方法，并被用来根据不同的方案调整每个测试系统的控制。所有仿真模型都是通过SimPowerSystem/Simulink生成的并可利用OPAL-RT的RT-LAB软件进行实时仿真；仿真模型的实时仿真性能也进行了探讨。* y+ a6 k" x$ J
