Abstract :
In the wind power flow optimization control system, 3-phase DC/AC converter is used to realize two-way flow of active power and reactive power, of which the key problem is that how to realize decoupling control of active current and reactive current. Traditional d-q decomposition method makes the design of control system complicated. In order to simplify the design of control system, p-q decomposition method is proposed based on instantaneous reactive power theory, which is used to establish 3-phase DC/AC converter´s mathematical model. The simulation using Matlab/simulink shows the feasibility of the modeling method.
