| Abstract: | A phase-shift algorithm for reactive electric power and energy in power systems is presented in this paper.The proposed algorithm is based on a difference of a quarter of periodic in time and a difference of 90° in phase.According to this principle,three algorithms,such as 90°,60° and 45° phase shift in instantaneous value,are proposed in this paper.60° phase shift algorithm is better in performance than other algorithms in reactive electric power and energy computation. |
| Keywords: | power systems reactive power reactive energy phase-shift |
