| 摘 要： | 介绍了轻型直流输电系统的结构特点,建立了基于电力系统仿真软件DIgSILENT/PowerFactory的轻型直流输电系统模型,分析了基于同步d-q旋转坐标系下的电压源换流器的稳态数学模型和直流电压、有功功率和无功功率的控制策略,对系统在直流电压、有功功率及无功功率变化条件下的动态性能进行了仿真。仿真结果表明,该系统具有很好的动态响应能力和鲁棒性,可以稳定工作于2个电网之间,独立控制无功功率达到静态无功补偿的作用。

| Abstract: | The paper introduced structure characteristics of HVDC-Light system,built model of HVDC-Light system based on power system simulation software DIgSILENT/PowerFactory,analyzed steady state mathematical model of voltage source converter based on synchronous d-q rotating coordinate system and control strategy of DC voltage,active power and reactive power,and simulated dynamic performance under condition of change of the DC voltage,active power and reactive power.The simulation results show that the system has good ability of dynamic response and robustness,can steady work between two power grids,and independently control reactive power to compensate static reactive power. |
