摘　　要：介绍多端高压直流输电系统的系统控制方法,建立轻型多端高压直流输电系统换流器暂态数学模型,设计出基于自抗扰控制技术的直流电压控制器和功率控制器,以便实现有功功率、无功功率的完全解耦控制。对所建模型进行的MATLAB/Simulink仿真结果表明,在交流系统电压变化、短路故障及直流系统有功功率、无功功率变化时,直流系统均能实现稳定运行。Introduces the master control method and establishes transient mathematical model for VSC-MTDC. Designes the DC voltage controller and power controller based on the theory of auto-distttrbance-rejection control, and realizes the purposes of full decoupling of active power and reactive power. The simulation results using MATLAB/Simulink show that changes of voltage in the AC system, short circuit faults and DC system active power or reactive power changes, DC power transmission system can achieve stable operation.
