This paper focuses on a wind farm power fluctuation which improved by using the variable-speed pump storage. The stator flux indirect field oriented control is used to control of pump storage. The two identical seven levels cascaded H-bridge multilevel converters (CHB-MLC) which connected in cascaded have been used to generate 6kV on the rotor side of pump storage. By using the CHB-MLC, total harmonic...
This paper presents a cascaded H-bridge multilevel converter for application in variable-speed pump storage. Most of the results are related the performance of the inverter voltage, rotor currents and speed when the 6kV wound router induction machine is fed by 11 level H bridge inverter. Multi carrier phase shift modulation is used to obtain 11 level phase voltage. The phase shift transformer is used...
