| 摘要: |
| 配电网内间歇性分布式电源和负荷的波动性使系统的运行稳定性、调控灵活性受到制约。对于大面积零散分布的工厂负荷和居民负荷，单端电压波动治理设备已无法满足要求。针对上述问题，研究了用于多条馈线互联的柔性多状态开关(Flexible Multi-state Switch, FMSS)电压波动治理技术。基于三端口FMSS的拓扑分析，分析了FMSS与三端馈线进行功率交换的原理。利用解耦控制策略，实现装置同时独立进行有功潮流和无功补偿两种功能。搭建了仿真模型，进行配电网三条馈线潮流控制和无功补偿功能验证。然后提出了无功协调控制优化模型，实现了多重化控制。仿真和优化结果显示，所提的开关模型电压波动治理快速有效。 |

| Abstract: |
| In the distribution network, the stability and flexibility are limited due to intermittent distributed power and loads. For scattered factory and residents, single-ended voltage fluctuation control equipment can’t meet the requirements. This paper studies the Flexible Multi-State Switch (FMSS) voltage fluctuation control technology for multiple feeder interconnections. Based on topology analysis, the power exchange principle is analyzed between FMSS and three-terminal feeder. The decoupling control strategy is used to realize active power flow and reactive power compensation independently. The simulation model is built to verify the above two functions. Then the multiple control is realized by the reactive power coordination control optimization model. Simulation and optimization results show that the switch model is fast and effective.
