一种考虑非对称αβ控制影响的单相轨道交通车辆-电网系统dq坐标系导纳建模优化方法

To tackle the small-signal instability in the single-phase railway vehicle-grid system, the dq admittance modeling method has received great attention. However, the orthogonal β components created by the asymmetric quadrature signal generators (QSGs) for dq control inevitably suffer from amplitude or phase errors at nonfundamental frequencies, which are not fully considered in the traditional dq m...
