This paper shows a new induction generation system for wind power generation. This system has the voltage source converter exciting induction generator and the PFC converter to transfer the real power. This configuration enables asynchronous link and maximum power tracking for the cage rotor induction generator. Usually two full rating inverter sets are necessary to construct the asynchronous link...
This paper investigates the new wind power generation system, which uses the diode rectifier to convert the real power from the induction generator to the intermediate DC voltage, and the inverter to supply the reactive power necessary to excite the induction generator. This scheme is expected to reduce the system cost. Control scheme and soft start strategy are verified by the simulation.
This paper shows new induction generation system for wind power generation. This system has the voltage source converter (VSC) exciting induction generator and the PFC converter to transfer the real power. Rated power of the VSC is minimized by transferring all the real power into the PFC converter. However, the harmonic components in the current from the VSC has larger peak than expected for the...
This paper investigates new system configuration of induction generator for wind power generation. Proposed system realizes the variable speed generation with small capacity of inverter by using PFC converter with a diode rectifier and a boost chopper as the active power converter. The inverter supplies the reactive power only for the induction generator. The reduction of the capacity of the inverter...
The buck-boost power factor corrected (PFC) converter has wide range of the DC output voltage. In this paper, the application for the V-connected inverter to reduce the cost of the inverter is proposed. First the balance of series connected smoothing capacitor voltage is discussed. Next, double converter configuration to reduce the input current ripple is discussed. Finally, a soft-switching method...
An emergency power supply (EPS) using an induction generator with a fly-wheel energy storage is investigated. Two different exciting systems for the wounded rotor winding have been investigated. The principles of the operation and experimental results are shown. The results of start-up and steady state condition indicate that the inverter rating is reduced fairly.
