摘要
针对现有灾害天气导致大规模停电情况下的应急供电和快速组网问题,本文提出了一种下垂系数自调节的应急电源分散下垂控制策略,在此控制策略的基础上设计了一种应急电源准同期策略。并开发了相应的应急电源自趋优控制器,在RTDS(Real Time Digital Simulator)半实物仿真中搭建了两台应急电源并机模型,真实模拟了实际现场环境,进行了半实物仿真实验验证。实验结果表明所提控制策略能够实现多应急电源的分散控制和自动平滑组网,提高灾害条件下的应急保电能力,保证重要负荷的可靠和不间断供电。
Aiming at the emergency power supplying and rapid networking in the case of large-scale power outage caused by the existing disaster weather,this paper proposes a distributed control strategy with self-adjusting droop coefficient for the emergency power source.Based on this control strategy,an automatic quasi-synchronization strategy for emergency power source is designed.And a self-optimizing controller is developed.Two emergency power sources parallel models are built in the RTDS(Real Time Digital Simulator)to simulate the actual environment.Semi-physical simulation experiments are carried out.The experimental results show that the proposed control method can realize distributed control and smooth networking of multiple emergency power sources,which can improve emergency power supplying capability under disaster conditions and ensure reliable and uninterrupted power supplying for important loads.
