Optimal Control Method of Transformer Reactance Based on Real Time Load
摘要
Abstract
In order to ensure the short-circuit current level of medium and low voltage bus bars in substation,it is necessary to select reasonable transformer reactance parameters to prevent the selection of related equipment caused by excessive three-phase short-circuit current.However,limiting the short-circuit current level of the power grid to increase the transformer impedance will also increase the transformer loss,which is not conducive to the economic operation of the power grid.According to the above problems,on the basis of comprehensive consideration of the operation reliability and economy of power grid,it proposes a real time load based transformer re-actance optimization method.According to the real time load of the transformer,this method taking the three-phase short circuit cur-rent,voltage regulation rate,and reactive power loss as constraints to optimize the optimal value of the reactance of the transformer un-der the current load,and comparing it with the actual reactance value of the transformer to obtain the reactance deviation value.Through the controllable series compensation technology,the inductance and capacitance are compensated,so that the overall react-ance value of the transformer unit is the optimal value.Simulation results show that the proposed method can coordinate user require-ments for power supply reliability and economy.关键词
