摘要

高比例电力电子变流器并网产生的同步稳定问题近年来得到了学术界和工业界的广泛关注。然而，当前研究大多聚焦锁相环非线性对同步稳定性的影响，较少关注变流器控制系统中限幅、饱和、死区等非线性在同步失稳中扮演的重要角色。该文研究变流器中的两种典型控制非线性——硬限幅非线性和圆限幅非线性对变流器大干扰同步稳定性的影响，定量分析非线性环节类型、位置、作用信号变化时系统同步方程的同构和异构性；进而，借助摄动平均法得到系统振荡解和大干扰同步稳定边界，定量分析运行工况、控制参数、限幅参数等关键因素对系统同步稳定性的影响。

Abstract

In recent years

the synchronization stability issues caused by high-penetration of power electronic converters have received extensive attention from both academia and industry. Current research focuses on the impact of the phase-locked loop on synchronization stability

but pays little attention to the impact of control nonlinearities

such as limiting

saturation

and dead zone on synchronization instability. This paper investigates the impact of two typical control nonlinearities

namely the hard limiter and circular limiter

on the large-signal synchronization stability of grid-tied converters. First

the isomorphism and heteromorphism of synchronization equations with different kinds of limiters are analyzed. Then

the system's analytical oscillating solutions and large-signal stability boundaries are proposed based on the method of averaging. Finally

the impacts on the synchronization stability from various factors including operating conditions

control parameters

and limiter parameters

are quantitatively revealed via the proposed stability boundaries.
