| 摘 要： | 通过分析单相动态无功补偿系统结构,提出了一种新型的单相动态无功电流检测算法,并将其应用于静止同步补偿器.所提算法通过三角函数的数学关系导出无功电流的计算方法,采用电压与电流的瞬时采样值直接得到无功电流的幅值,是一种动态无功电流的瞬时采样直接法.该算法的控制目标是使补偿装置发出的电流为系统的无功电流,结构简单且易于实现,...

| Abstract: | Based on the analysis of its system structure,a detection algorithm of single-phase dynamic reactive current is presented and applied to STATCOM.The reactive current amplitude is calculated directly from the instantaneous samplings of voltage and current by means of the mathematic relation of trigonometric function.Its control objective is to keep the output current same as the system reactive current.It is simple,easy to realize,and immune to capacitive or inductive load current.Its total calculation time ... |
