| 摘要: |
| 提出一种兼顾抑制低频功率振荡和提高暂态电压稳定性的动态无功补偿装置控制方法。首先通过一个典型的含有动态无功补偿装置的系统分析了阻尼低频功率振荡和保持母线电压稳定2个控制目标相互影响的机理。在此基础上提出在电压控制和阻尼控制两者出现矛盾的时候，通过协调优化算法，选取最优的无功控制指令，防止阻尼控制引起电网电压超标。在典型电网系统中开展了仿真研究，结果表明所提方法可以实现电压控制和阻尼控制的协调，在确保电压控制效果的前提下尽可能抑制低频功率振荡。 |

| Abstract: |
| A control method of dynamic reactive power compensator is proposed，which coordinates the suppression of low-frequency power oscillation and the voltage stability. The interaction of two control objectives，damping control and voltage control，are analyzed based on a typical power grid with a dynamic reactive power compensator and an optimization algorithm is proposed，which selects the optimal reactive power reference when there is conflict between two control objectives to prevent the grid over-voltage caused by damping control. Simulative results show its effectiveness. |
