| 摘要: |
| 在特高压直流换流站配置同步调相机可以给交流电网提供动态支撑、提高系统稳定性，但当前调相机与换流站交流滤波器均为单独控制，两者之间缺乏合理的协调配合。针对此问题，考虑调相机与换流站交流滤波器现有的控制策略及特性，提出一种稳态无功功率协调控制策略。于两者控制系统之间实现数据交互，在确保不影响调相机对交流电网动态支撑作用的前提下，直流控制系统调用调相机稳态无功容量的一部分，与换流站交流滤波器配合进行无功功率平衡控制，充分发挥了调相机的无功补偿作用。最后，通过仿真验证了该策略的有效性。 |

| Abstract: |
| Equipped with synchronous condenser in UHVDC converter station can provide dynamic support for AC network and improve system stability, but the current synchronous condenser and the AC filter in converter station are controlled separately, and there is no logical coordination between them. In view of this problem, considering the existing control strategies and characteristics of synchronous condenser and AC filter in converter station, a steady state reactive power coordinated control strategy is proposed. The data exchange between the control systems of them is realized. On the premise of ensuring that the dynamic support function of the synchronous condenser to AC network is not affected, the DC control system calls part of the steady-state reactive power capacity of the synchronous condenser to make it cooperate with the AC filter in converter station for reactive power balance control, thus giving full play to the role of reactive power compensation of the synchronous condenser. Finally, the strategy is validated by the simulation test. This work is supported by Science and Technology Project of the Headquarters of State Grid Corporation of China (No. 52153218000H). |
