Abstract
|
Through the current power system reactive power shortage , power quality factor is low, three-phase unbalanced load , the traditional TSC reactive power compensation harmonic amplification may exist , as well as reactive power compensation in the existence of \a detailed analysis of the problem , proposed and designed specific solutions . There are contacts for traditional and non-contact reactive power compensation device has the disadvantage of reactive power compensation level is proposed using photoelectric control triac MOC3061 Triac drive to achieve stepless switching capacitor novel method for reactive power compensation . For reactive power compensation exists harmonic problem, a high-pass filter using monotone concordant for harmonic filtering approach. Reactive power compensation for traditional harmonic potential problem with the method proposed using series reactors to prevent harmonic amplification design. While for the most current reactive power compensation devices are single- point compensation of reactive power optimization design of multi-point in the power system reactive power compensation on the optimal use of all of the controllers proposed simultaneous sampling , carried out on all the nodes after optimization , beginning from the last node passed along the optimal control strategy optimization . On this basis , summarizes the various project specific design aspects of reactive power compensation for industrial application development direction in the future, that the active filter of the power system will be the future power system reactive power compensation and harmonic filtering key development direction .
