摘要
Reactive voltage characteristics of typical regional power grid is analyzed.To the existing var/vol problems,inductive reactive compensation scheme is proposed.The comparative analysis of the formula of high-voltage and Low-voltage inductive compensation method are proposed based on the estimation model of reactive power compensation and voltage regulation.A compare system from multiple angles(incluing the effect of voltage regulation,adapt to the future development trend of the grid,economy,newly installed substations feasibility compensation device) were pointed out.A comprehensive comparison based onseveral angles above was made through simulation results of the case.Calculate results show that: The comparative analysis of the formula of high-voltage and Low-voltage inductive compensation is proposed in the paper has a high precision,the voltage regulator effect can be estimated by the proposed formulations and low-voltage inductive compensation method is superior to high-voltage inductive compensation method.
