In view of such problems as insufficient reactive power and three-phase unbalance in distribution station area of China

in this paper

the adjustment principle of reactive power and three-phase unbalance is analyzed.It is proposed in this paper to use such hybrid compensation proposal and optimization control strategy as phase to phase compensation capacitance

independent phase compensation capacitance and dynamic compensation in accordance with the advantage and disadvantage of application of pure dynamic compensation device and capacitor compensation in the distribution station area and also with the minimum operation capacity of the dynamic compensation equipment as optimization target.The identical compensation result of the dynamic compensation which is achieved by the optimal control strategy of the hybrid compensation is verified by the simulation model

and the economic operation feature of loss of the whole machine by 2/3 is also verified.Finally

correctness of the configuration method of the hybrid compensation device and the feasibility of the optimized control strategy are verified by the engineering application.
