| 摘要: |
| 在MATLAB／Simulink平台搭建了三端并联型电压源换流器型多端直流输电（VSC-MTDC）仿真模型，分别设计了基于预测-直接功率控制（P-DPC）的本地控制器和协调控制器。当某个变流站发生扰动甚至退出时，由主导变流站进行功率补偿，若主导变流站达到功率出额上限，具有功率调节的变流站切换运行模式，自动承担缺额功率，保证系统稳定运行。各个变流站工作相对独立，提高了系统稳定性。仿真表明所设计的控制器简单，控制效果相对于传统双闭环控制策略更好。 |

| Abstract: |
| A simulation model of three-terminal parallel VSC-MTDC（Voltage-Source Converter based Multi-Terminal HVDC transmission） is built on MATLAB／Simulink platform，and the local controller and coordinating controller are respectively designed based on P-DPC（Predictive-Direct Power Control）. When one converter station is disturbed or out of operation，the main converter station then provides the compensating power；when the main converter station reaches the upper limit of power output，a converter station with power regulation function will change its operating mode to automatically assume the power vacancy for ensuring the stable system operation. The operation of each converter station is relatively independent to improve the system stability. The simulative results show that the designed controller is simple and its control effect is better than that of traditional dual closed-loop control strategy. |
