With The Research And Implementation Of Reactive Power Compensation Techniques

Reactive power compensation can save power, stabilize voltage, reduce waste of transition electricity, and reduce capacity of power devices. By far, there are problems in reactive power compensation technology. To solve the current impulse problem when the non-contactor switch on or cut off the capacitance, we particularly design the main circuit and the trigger circuit and use the open-off ratio control ways to eliminate impulse current. In order to shun the current resonance, we use series inductance in main circuit to avoid the harmonic current by theory computation. We add voltage harmonic filter to reduce the harm which voltage harmonic do to power system. In the severe power system unbalance situation, we use the power balance implement principle to do reactive compensation, we can make the power factor reach given value and make the three-phase load become balance in the same time. We make the power factor get optimum control effect by using optimum control theory to a single control appliance. To multi-appliance, first we get the most optimum reactive compensation nodes in lines, then we use Dynamic Programming algorithm to the control ways of least energy consume by cooperating the appliance. Based on such study, we give some gives some suggests for the future development.
