Research on Reactive Power Compensation Technology of Double-fed Machine

Constant apparent reactive power compensation technology of the Double-fed Machine is studied theoretically, and the mathematical models of constant apparent power control are established in accordance with vector control of the Double-fed Machine. Theoretical analysis and simulation results show the model and the control strategy is feasible. It not only can make full use of reserve capacity of the motor, but also can send reactive power to the electricity network, enhance the operating efficiency of the system and save energy.
