The ZIP file Circulation_inhibition includes four items:

1. simulation 1: xianluzuk_bili1, which is the parallel connection of two inverters, the line impedance is proportional simulation.

2. simulation 2: xianluzuk_buchengbili2,which is the parallel connection of two inverters, the line impedance is not proportional simulation.

3.simulation 3: xianluk_buchengbili_xunizukang3, which is the parallel connection of two inverters, the line impedance is not proportional,and virtual impedance is added.
