Abstract In the electrically excited synchronous motor (ESM) based inertia wheel energy storage DC supply system,there are three degrees of freedom from the control consideration,i.e.the stator flux,the power factor,and the DC-link voltage.To reduce the system reactive power and increase the efficiency,the DC-link voltage should be stabilized and the power factor should be increased.In this paper,a novel unity power factor control scheme for ESM is proposed,in which we degrade the control freedom and perform the close-loop control on power factor and DC-link voltage in a rotor-oriented reference frame.Simulation and experiment carried out in an inertia wheel energy storage system show that,compared with the traditional isd=0 scheme,the proposed scheme increases the power factor to 0.97,and realizes a 28% down of the apparent power,which effectively reduces the system reactive power.
