An Induction Wind Power System with Grading Control of Capacitance and Load

Aiming for the application in petroleum-heating field, an induction wind power generation system with graded capacitors and load is designed. The system is simple, reliable and low cost. Under variable generator speeds, the output voltage variation is controllable by switching the graded capacitors, and the output power is adjusted to guarantee the effective utilization of the wind power. The optimization model of the system is set up to calculate the optimal values of excitation capacitance and load that need at different speeds. Simulation and experiment results verify the validity and feasibility of the system.
