| This design first introduced that our country has many problems in the aspect of reactive voltage management in the electrical network, then on these question existed, the design explained optimizes the practical significance to the electrical network implementation voltage idle work. Through the simple introduction of the AVC system, it elaborated the essential target of system is to realize the voltage adjustment, the power factor adjustment and the net damages the optimization, also the question of keeping the voltage to be qualified and the realization of the idle work balance. Through analyzing the basic principle of AVC, the design obtained the control method of realization of voltage to be qualified ad the idle work balance mainly has two kinds: The adjustment of the regulating transformer and the capacity or throws or cuts. Based on how to realize the voltage and the idle work optimization, it has drawn out many kind of optimized algorithms, but the voltage idle work control system in the present area electrical network most uses the linear programming law. Obtaining the sensitivity of the equipment to the generatrix voltage, the power factor and the net damages through the computation, unifying the control principle of nine areas charts, thus it realizes the control of the voltage and the idle work optimized. Finally, according to the performance index request of local electrical network AVC, Carry on an implement according to the superior project finally, and put forward checking before acceptance the standard and movement to manage a rules distance.
