A Simulation Study of Inverter Air Conditioner Controlled to Supply Reactive Power

Recently, inverter has been applied in air conditioning technologies. Besides energy saving capability, inverter can also control reactive power by using the dq-axis theory. It separates current into two parts that enable decoupled control of active power and reactive power. This presents a simulation study of an inverter air conditioner controlled to supply reactive power for the installation area without sacrificing thermal comfort. Power factor improvement can reduce loss in transformer and line so power that be saved can be used for others load. Simulation results carried out by MATLAB/SIMULINK showed that reactive power controllability depends on variation of the indoor and outdoor temperature and rated current of equipment.
