摘要

随着可再生能源的大力发展，逆变器并网装置不断增加，多逆变器并网系统谐振特性愈发复杂，谐波激励源频率与系统谐振频率相匹配后将会发生严重的谐波谐振事故。为完全掌握多逆变器并网系统的谐振特性，该文首先基于单逆变器并网系统结构和逆变器控制框图建立其对应的等效诺顿电路模型，然后得到多逆变器并网系统等效模型。提出一种全面的谐振评估方法，运用模态分析法得到并网系统的谐振情况；再根据参与因子法得到逆变器节点、传输线节点、公共连接点对谐振的参与程度，通过阻抗影响度和频率影响度指标进一步研究逆变器各参数对谐振的影响程度，以三逆变器并网系统为例进行谐振评估。最后，对所提谐振评估方法进行仿真验证，为逆变器参数设计以及系统谐振治理提供依据。

Abstract

With the rapid development of renewable energy sources

the number of inverter grid-connected installations continues to increase

leading to increasingly complex harmonic resonance characteristics of multi-inverter grid systems. Serious harmonic resonance accidents will occur when the excitation frequency of harmonic sources matches the system’s resonant frequency. To comprehensively grasp the harmonic resonance characteristics of multi-inverter grid systems

in this paper we first establish the corresponding equivalent Norton circuit model based on the structure of a single inverter grid system and the inverter control diagram. Then

the model is extended to obtain an equivalent model for multi-inverter grid systems. A comprehensive resonance assessment method is proposed

utilizing modal analysis to determine the resonance conditions of the grid-connected system. Furthermore

the participation degree of inverter nodes

transmission line nodes

and common connection points in resonance is determined using the participation factor method. The impact of various inverter parameters on resonance is further investigated by analyzing the impedance and frequency influence indicators. A three-inverter grid system is utilized as a case study for harmonic resonance assessment. Finally

the proposed harmonic resonance assessment method is validated through simulation

providing a basis for inverter parameter design and system resonance control.
