The Study Of Active Power Compension Of Enterprise Distribution Power System On Load Characteristic

Enterprise distribution power system serves directly to manufacture, the energy quality and power supply reliability are important to the development of enterprises. In view of the component of enterprise load ,the study on the establishment of load model and improve the situation of energy—saving have important theoretical and practical value.Firstly, the static load model, the dynamic load model,the assembly induction motors equivalent model was compared in the paper from identification, precision, etc. In view of the fact that induction motors are the main element of enterprise load , third-order electromechanical transient model, a transient voltage-order model, a transient band mechanical model are not the appropriate choice of enterprise distribution power system. Secondly, assembly induction motors load model is up to the fact of enterprise , the amount of computation and the precision of active power and reactive power can better meet the requirements of the analysis and calculation of enterprise distribution power system analysis. On the basis of the of above study production ,back/forward sweep method for radial distribution load flow was used to analyse the operating conditions of enterprise in the paper. The results of numeration was applied to the decentralized or centralized reactive power compensation .The load model and the compensation algorithm have been tested .The results indicate that they are effective in the analyze and calculation of enterprise distribution power system.
