摘要
随着配电网和负载的功率日益增加及波动频繁,对无功补偿方法的容量和快速性提出了更高的需求。针对现有无功补偿方法无法满足配电网和负载对无功补偿容量大、快速性的需求,文章提出一种大容量无功快速补偿方法。该方法采用分级投切电容器和连续可调电容器协调配合,分级投切电容器对系统进行大容量的基准无功补偿,连续可调电容器进行快速精准的微调无功补偿,提高系统的功率因数,使大容量配电网或负载的功率因数维持在目标值。利用Matlab/Simulink完成了补偿系统的仿真设计和分析,验证了大容量无功快速补偿方法的合理性和有效性。
With the increasing and frequent fluctuation of power distribution network and load, higher requirement to the capacity and rapidity of the reactive power compensation method is raised. In view of the existing reactive power compensation method has no way to meet the requirement of the distribution network and load to high reactive compensation capacity and rapidity, in this paper, a kind of high capacity and fast compensation method is proposed. The method adopts the coordination of the switching capacitor and the continuously adjustable capacitor. The former performs high capacity reference reactive power compensation to the system, while the latter performs fast and accurate fine tune reactive compensation, so to improve the power factor of the system keep the power factor of the high power distribution network or load at the target value. The simulation and design of the compensation system is finished by the use of Matlab/Simulink and both reasonableness and effectiveness of the high capacity fast reactive power compensation method is verified.
