Abstract
Detecting the reference compensation current quickly and accurately is one of the most important elements for improving the compensation performance of distribution static synchronous ( DSTATCOM) .Traditional compensa-tion current detection under the condition of asymmetric signals and distortion will introduce measurement errors.On the basis of summarizing existing compensation current detection methods, this paper proposed a method without phase lock loop ( PLL) .This method replaced the phase lock loop through the calculation of three-phase positive sequence voltage, which solved the problem of phase angle error introduced by PLL, and introduced the mean filter and feed-back loop to reduce the delay.The simulation results verify the effectiveness of the improved detection method.关键词
