Based On The "Five-Zone" Principles Of Substation Voltage And Reactive Power Control Strategy

In this paper,through the theory of reactive power control in basic research,we analysis the details of the Beijing power grid of reactive power compensation equipment,and understand the voltage control between the regulation of transformer and Switched Capacitor.Use the practical control strategy to examine how to get a more reasonable sub-district reactive compensation,and this paper introduce a brief of various reactive power control strategy,and also analysis the control strategies and scope of application prospects."Nine- Zone" theory of the field of voltage and reactive power control has been the classic control theory,but there is also dispersed and random problems in the analysis of information operations,the actual performance of control equipment is frequent adjustment.According to the view of the current control strategy and the impact caused by frequent adjustment frequency and voltage fluctuations.This paper improves a rationalization of VQC principle - the "five-zone" theory,we program a new algorithm forming at the border and start-up value,and from the mathematical model,software realization of value and norms in several aspects of the theoretical analysis.We get the practical results using powerful software simulation PSCAD.Analysis shows that the "five zones" is a practical control easy to realize the principle of VQC.
