A NEW ALGORITHM FOR OP TIMIZATION OF REACTIVE POWER IN DISTRIBUTION SYSTEM

This paper presents a new algorithm in regard to reactive power optimization for distribution system based on the features of oilfield distribution system. A mathematical model for the distribution system is developed and used to calculate power flow. Based on the power flow, the rational capacity and distribution of reactive power is determined. The balance of reactive power is realized in the place of user. An example proves that the new algorithm is benefit to reduce the energy losses of distribution line and raise the economical efficiency on optimal reactive power.
