摘要
针对天然气行业的负荷波动迅速和低功率因数问题,提出了采用SVG型动态无功补偿装置改善电能质量的方法。分析SVG的基本原理,推导基于分相瞬时控制策略的数学模型,通过实验平台论证该控制策略能迅速响应系统变化。在推导SVG本体损耗的基础上,结合工程实际论证SVG能够改善系统功率因数、降低系统损耗。
In this paper,SVG is proposed to solve quick fluctuating load and low power factor problems. Firstly,the basic principle of SVG is analyzed. Then the mathematical model is derived based on the instantaneous control strategy,which is proved fast response by experiment. Finally,with the derivation of SVG loss,the engineering practice proves SVG can improve the power factor of the system and reduce the loss of the system.
