Design on Closed-loop Control System for Voltage and Reactive Power Optimizing in Local Power Grid
Wu Yinfeng (Jiangxi University of Science and Technology)
The technical proposal of voltage reactive power optimization control system in local power grid is elaborated. From the angle of the whole power grid,the system can optimize the closed-loop control of reactive voltage by "four telecontrol" function in dispatching automation system. It carries out the exact application of reactive compensator and the on-load tap appropriate changer for voltage regulation transformers,and realizes the balance of reactive voltage in local site. Thus the target of improving the quality of power grid and minimizing the transmission cost can be obtained. Through the system,the automation level,the reliability and the profitability of local power grid can be greatly improved.
