The paper demonstrates phasor and time domain hybrid simulation in real-time. A 55bus distribution grid is simulated in phasor domain and a solar photovoltaic with battery storage and some residential loads are modeled in time domain. This hybrid simulation is achieved using OPAL-RT Technologies real time solution called ePHASORsim for phasor domain and eMEGAsim for the time domain simulation. In...
There are many limitations to applying on-line spectrum analysis techniques for diagnosis of closed loop inverter-fed induction motors due to variable load or frequency operation, and the masking effect of the current regulator. In this paper, a new automated approach for testing inverter-fed induction machines for airgap eccentricity is proposed. The main concept is to use the inverter to excite...
