针对微电网孤岛运行模式下逆变器线路出现单相接地高阻故障引起的系统电压不平衡的问题，提出一种基于残差生成器的零轴高阻故障检测和容错控制方法，以降低系统电压的不平衡度。首先，建立四桥臂逆变器dq0轴的状态空间模型，分析高阻故障对输出电压的影响。其次，基于左右互质分解和欧拉参数化理论设计残差生成器得到残差，利用巴特沃斯带通滤波器生成零轴残差分量，进行故障检测。然后，从零轴扰动对消的角度通过模型匹配理论设计零轴容错控制器，并利用线性矩阵不等式法进行求解。最后，利用PXI半实物仿真平台进行高阻故障检测和容错控制实验，验证该方法的可行性。

Aimed at the problem of system voltage imbalance caused by single-phase grounding high-resistance faults in inverter lines in an islanding operation mode of microgrids, a zero-axis high-resistance fault detection and fault-tolerant control method based on a residual generator is proposed to reduce the degree of system voltage imbalance. First, a state space model for the dq0 axis of a four-bridge-arm inverter is established, and the impact of high-resistance faults on output voltage is analyzed. Second, based on the theory of left and right coprime decomposition and Euler parameterization, a residual generator is designed to obtain residuals, and a Butterworth bandpass filter is used to generate zero-axis residual components for fault detection. Third, from the perspective of zero-axis disturbance cancellation, a zero-axis fault-tolerant controller is designed using the model matching theory, which is further solved using a linear matrix inequality method. Finally, high-resistance fault detection and fault-tolerant control experiments were conducted using a PXI semi-physical simulation platform to verify the feasibility of the proposed method.
