【Abstract】 Based on Newton method,considering the particularity of distribution networks,this paper presents a new three phase load method with constant Jacobian matrix for unbalanced distribution system analysis.The method introduces cogenerators to slack bus for disposal of the unbalance voltage of this bus.With rational assumption on the load flow bus,the Jacobian matrix of the method is constant and has no change in the process of iteration.Furthermore,the method does not decouple and high R/X ratio dose not deteriorate its convergence;it can also be used in meshed distribution networks.Finally,tests on several distribution systems have shown that the proposal method is robust and efficient.更多还原
