基于几何相似性测度的并网双向T型变换器开路故障诊断方法

Grid-connected bidirectional T-type converter (GBTC) is widely used in power generation, vehicle-to-grid, and other applications because of its bidirectional energy flow and superior performance. However, transistor open-circuit fault can cause serious output harmonics and even system outage. In this work, a novel open-circuit fault diagnosis method is proposed based on geometrical similarity meas...
