Simulation Study of Wind Power with Continuously Variable Transmission

摘要：

Working principle of continuously variable transmission (CVT) applying in wind power system is analyzed. Mathematic model of CVT in wind power is established. Compared with fixed pitch wind power, the relation between wind energy utilization coefficient, power and wind speed are studied. Dynamic simulations of CVT wind power system are researched in random wind speeds. The CVT transmission ratio, wind turbine rotational speed, wind energy utilization coefficient, generators rotational speed, wind turbine power and generator power are simulated when wind speed signals are random changed. Simulation results show that wind power applying CVT makes wind turbine operate at an optimal blade tip ratio, obtain an optimal wind energy utilizing coefficient, take full advantage of wind energy and be superior to fixed pitch wind power. Generator outputs constant frequency voltage and smoothly variable powers without applying other electric power and electronic equipments.
