静态同步补偿器在民用建筑供电系统的应用

Application of Static Synchronous Compensator in Power Supply System of Civil Buildings

针对民用建筑供电系统的无功补偿问题,结合民用建筑供电系统容量小、三相载荷不平衡的特点,对静态同步补偿器原理进行分析,阐述其存在的两方面不足,然后提出静态同步补偿器的改进技术,包括无功电流检测技术、静态同步补偿器模型改进及电流间接控制法,以提升补偿器对不平衡负载的适应性和稳定鲁棒性。

Aiming at the problem of reactive power compensation in civil building power supply system,combined with the characteristics of small capacity and unbalanced three-phase load of civil building power supply system,this paper analyzes the principle of static synchronous compensator,expounds its two shortcomings,and puts forward the improvement technology of static synchronous compensator,including reactive current detection technology,static synchronous compensator model improvement and current indirect control In order to improve the adaptability and stability robustness of the compensator to unbalanced load.
