Exploration of Composite Solar and Wind Power Generation Device Control

Abstract:

Recently, Solar energy and wind energy composite wind turbine by a number of studies have been carried out to examine the fault-ride through capability of the DFIG system during network disturbance. Whereas for all the work reported, the network voltage was assumed to be symmetrical. However, in practice, asymmetric faults occur more frequently than symmetric ones. For a DFIG system, if the voltage unbalance is not considered in the control system, the stator current could be highly unbalanced even with a small unbalanced stator voltage. The unbalanced currents create unequal heating among stator windings and torque pulsation in the generator. A wind-turbine driven DFIG without unbalancing voltage control considered might have to be disconnected from the network during network voltage unbalance.
