中文摘要

本文研究了基于二阶广义积分器(SOGI)的信号处理与同步算法。通过级联多个SOGI,可实现单相信号的频率分量分解及幅值相位检测。文章重点探讨了该类算法的线性时变(LTP)建模方法,并对其在复杂电网环境下的稳定性进行了深入评估。

English Abstract

A second-order generalized integrator (SOGI) is a resonant regulator with a pair of complex-conjugate poles, and therefore, with infinite magnitude at its center frequency. Thanks to this property, one can put together a set of $m$ SOGIs in an elegant way and decompose a single-phase signal into its constituent frequency components and detect their amplitude and phase angle. Such a configuration, ...

该技术对阳光电源的核心产品线(如组串式光伏逆变器、户用逆变器及储能变流器PCS)至关重要。SOGI是实现锁相环(PLL)和电网同步的核心算法,直接决定了逆变器在弱电网、谐波干扰及频率波动环境下的并网稳定性。通过对SOGI变体的LTP建模分析,研发团队可优化控制环路设计,提升逆变器在复杂电网下的鲁棒性,减少因同步失稳导致的脱网风险。建议将该稳定性评估方法集成至iSolarCloud智能运维平台的仿真模型中,以提升对电网适应性的预判能力。
