摘　　要：随着特高压交直流的快速发展和电网结构越来越密集,核电、煤电、燃机等大规模电源的接入,系统分析变得越来越复杂。本文在充分考虑安全性、稳定性和经济性等指标的基础上,提出了基于AHP-反熵权法的大电源接入电压等级确定方法。该方法的首要步骤是应用层次分析方式得出最终的目标判断范畴内容,之后整合计算的权重数据信息,最后应用常用的反熵权法计算出指标权重来进行综合评价。实例表明,该方法对综合评估大电源接入系统方案具有较大指导意义。Along with the rapid development of UHV DC and AC systems and strong connected power grids,the analysis of large power source access,such as,nuclear power unit,coal unit and gas turbine unit,is becoming more and more complex.Considering the indexes about security,stability and economy,a determination method of voltage level to be connected with large power source is proposed based on AHP-anti-entropy weight method.At first,The AHP is utilized to obtain the judgement matrix of the objective layer and calculate the weight vector.Then,the anti-entropy weight method is employed to evaluate the weight of indictors for comprehensive evaluation.Numerical examples demonstrate the proposed method is of great importance for the evaluation of large power source access.
