The UPS system has a controller having a dual gain voltage regulator for controlling the output voltage of the inverter of a UPS system that uses active and reactive current components of a load current flowing out an output of the UPS system.Chen, Xian...
Instantaneous active and reactive current control technique of shunt active power filter based on the three-level NPC inverter In this paper, the synthesis and performance of a shunt active power filter (SAPF) based on instantaneous active, and reactive current components (idiq) te... E Pouresm...
This paper deals with the design of a predictive-integral current controller for wind generators connected to the grid. The goal is to achieve a decoupled control of d-and q-axes current components at the connection point, which results in a decoupled control of the active and the reac-tive...
Reactive power compensating apparatus with higher harmonic suppressing function Higher harmonic power components and fundamental wave reactive power components are derived from a load voltage and current, using theory (instantaneous p-q theory) regarding instantaneous real power and instantaneous imaginary powe...
In AC electrical systems, phase-shifting between voltage and current introduces the concept of complex power, which has active power, reactive power, and apparent power as its components. Understanding complex power is fundamentally important for AC electrical system analysis, operation, a...
