基于正序瞬时功率算法的宽频振荡检测技术
A wideband oscillation detection technology based on positive sequence instantaneous power algorithm
摘要
Abstract
Modern power systems exhibit an integration of high proportion of renewable energy sources and high pro-portion of power electronics,commonly referred to as'double high'power systems.The interplay between harmon-ics,interharmonics,and power frequency components at varying frequencies within the power system can induce wideband oscillations,posing a substantial threat to its secure and stable operation.In response to the challenge of precisely identifying wideband oscillations in the presence of three-phase imbalance,the paper proposes a wideband oscillation detection technology using the FPGA(field programmable gate array)and positive-sequence instanta-neous power method.Since the three-phase positive sequence instantaneous power can effectively filter out the three-phase unbalanced components,the method ensures that the result of wideband oscillation detection is not compro-mised by such imbalances.The incorporation of FPGA's parallel computing capability significantly enhances the performance of the wideband oscillation detection method.Test results validate the accuracy of this technology in de-tecting oscillation components during wideband oscillations,effectively addressing misjudgment and insufficient parallel computing capacity in existing technologies.关键词
