Optimal Configuration of Inductive Reactive Power Compensators in Regional Power Network

The thinking and method to implment optimal configuration of inductive reactive power compensation for regional power network are proposed,and an inductive reactive power compensation model for regional power network,in which the voltage quality,cost of investment and operating cost optimization of whole netword are considered,is built to solve the problem,namely in regional power network the voltage is near the upper limit that is caused by the surplus of capacitive reactive power due to grid-connection of large amount of distributed generations(DGs),for instance the small hydropower stations,during low load operation mode.The calculation of inductive reactive power optimization is performem for a certain regional power network,and the obtained results are compared with those results calculated by project estimation method and average power factor method.Simulation results show that after the optimal configuration of inductive reactive power compensation according to the proposed optimization scheme,the reactive power level and voltage level in the simulated region are evidently improved.
