摘要
分析了静止无功发生器 (SVG)对干扰性负荷的无功及谐波综合补偿原理。针对电气化铁路牵引供电系统的特点 ,结合瞬时无功功率理论 ,给出综合补偿的 ip iq矢量控制算法 ,并进行了计算机仿真。
This paper analyses the principle of comprehensive compensation for the reactive power and the harmonics with the interference loads by using SVG. Based on the feature of the electric railway powor supply system and the reactive power theory,the paper presents a vector control algorithm for i p and i q comprehensive compensation,then,a computer simulation is given.
