| Abstract: | A novel method of instantaneous current compensated for reactive power in 3 - phase 4 -wire system is proposed in this paper, which is based on new defined of generalized instantaneous reactive current in 3 - phase 4 - wire in coordinates. Research of instantaneous reactive power in 3 - phase 4 - wire based on coordinates and good simulation results are also presented in this paper. |
