摘要

为研究不同拓扑结构混合直流输电系统的特性

设计并研制了由电网换相换流器（LCC）和电压源换流器（VSC）共同构成的混合直流输电实验平台

该平台不仅可以灵活构建多种混合直流拓扑结构

而且其控制系统架构也同样适应于多种混合直流拓扑的系统控制需求。首先

设计了混合直流输电实验平台主电路系统与控制系统的结构与功能

构建了由系统级控制和阀基控制器组成的通用控制器架构。然后

开发调试了控制系统的通信规约与核心算法程序。最后

以LCC整流–VSC逆变型混合直流输电模式为例

在稳态工作条件下进行了直流电流与电压阶跃的实验。实验结果验证了实验平台整体设计的合理性以及良好的稳态特性

对混合直流输电相关的实验研究有重要的意义。

Abstract

To research the characteristics of hybrid HVDC systems with different structures

we designed and developed an experimental platform composed of Line Commutated Converter（LCC） and Voltage Sourced Converter（VSC） modules. By flexibly combining different modules

various hybrid HVDC structures can be constructed

and its control system framework can meet the requirements of the system control for various hybrid HVDC topologies. Firstly

we designed a main circuit and control structure of the experimental platform and constructed a general control framework composed of systematical and valve-based controllers. Then

we established a communication protocol and programmed the core control algorithm for the overall system. Finally

we conducted the DC current and voltage step-change experiments based on the hybrid HVDC structure

which adopted LCC as rectifier and VSC as inverter. The experimental results have proved the adaptability of the overall design of the experiment platform and its benign features under stable conditions

which is of great importance to related researches on hybrid DC transmission systems.
