MEDIUM-VOLTAGE THREE-PHASE ENERGY CONVERSION SYSTEM TO ENGAGE A POWER SOURCE TO AN ELECTRICAL SUPPLY NETWORK

摘要

a medium voltage three phase power conversion system for coupling a power source to an electrical supply network. comprises a power converter (51) and a notch filter (53). the switching control system (67) of the inverter (65) of the power converter (51) is a medium voltage three phase power conversion system for coupling a power source to an electrical supply network. comprises a power converter (51) and a notch filter (53). the switching control system (67) of the inverter (65) of the power converter (51) is based on she-pwm standards. the filter-? notch? (53) is arranged to attenuate the frequency of the first harmonic that the switching control system (67) of the inverter (65) cannot attenuate and configured with damping means capable of smoothing the resonant frequency without affecting the notch frequency. .
