【摘要】 变压器故障或者N-1检修情况下快速高效的负荷转移是保证供电的有效措施之一。一般凭经验获得的负荷转移方案是可行方案,如何快速求取最优方案是亟待解决的问题。文中针对电网故障下负荷转移的特点、问题以及系统安全运行的约束,提出基于快速性、经济性及稳定性因素的优化决策模型,并利用模糊层次分析法(FAHP)确定最优负荷转移方案,为现场的调度人员提供决策依据。最后以国内某电网为例进行仿真,结果表明本文提出的负荷转移优化决策方法具有可行性、快速性和有效性。更多还原

【Abstract】 Load transfer is one of effective measures to guarantee the security of power supply under transformer fault or N-1 maintenance.The load transfer scheme obtained by experience is feasible.How to get the optimized scheme rapidly is a critical issue.As to the characteristics of load transfer and the constraints of system security operation,the optimal decision-making model which considers such fac- tors as swiftness,economy and stability is proposed in this paper,and the optimized load transfer scheme is obtained by use of Fuzzy Analytic Hierarchy Process(FAHP),which provides a scientific decision reference for dispatchers.In the end,the feasibility,fastness and effectiveness of this optimized decision-making method for load transfer are verified through an example of a regional power grid.更多还原
