要約(日本語): This paper presents a linear definition of active and reactive current for analysis of parallel-connected UPS system. It involves vector and axis rotation in order to show the relation between d-q components of the current and active and reactive current. The coherence of this expression is demonstrated through comparison with the calculation obtained from an elementary circuit representing a parallel-connected UPS system and the simulation using the same circuit and a time-based expression for active and reactive current. Three situations are verified and, in all of them, the results evidence the coherence of the linearized expression of active and reactive current.
