基于正序瞬时功率算法的宽频振荡检测技术OACSTPCD
A wideband oscillation detection technology based on positive sequence instantaneous power algorithm
现代电力系统表现出含高比例可再生能源和高比例电力电子设备的"双高"特征,电力系统中不同频率的谐波、间谐波与工频量相互作用,将可能导致宽频振荡,威胁电力系统安全稳定运行.针对无法在三相不平衡状态下实现宽频振荡准确检测的问题,提出了基于FPGA(现场可编程门阵列)和正序瞬时功率算法的宽频振荡检测技术.利用三相正序瞬时功率能滤除三相不平衡分量的原理,确保宽频振荡的检测结果不受三相不平衡的影响.利用FPGA并行计算的特性,大幅提升了宽频振荡检测算法的性能…查看全部>>
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 wid…查看全部>>
