摘要 通过对1种点乘移相算法来计算无功功率和电能的分析,提出了3种移相算法:瞬时值90°移相算法、瞬时值60°移相算法和瞬时值45°移相算法。并经实例分析得出60°移相算法在无功功率和电能计算精度上具有较好的优势。 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.
