摘　　要：为了对配电网规划方案进行全面有效的评估,从技术性和经济性两方面构建了配电网规划方案三级评估指标体系。提出了基于突变理论的配电网规划方案综合评估方法,该方法利用系统状态量在临界点附近非连续变化的特征,采用突变决策归一化公式提取系统突变级数,避免了常规的评估方法对评价指标采用权重的方式,减少了决策的主观性,使决策更符合实际。以某地区配电网规划方案的实际数据为例,并且与其他常用的评估方法进行对比分析,验证了所提出方法的有效性和准确性。To evaluate distributed network planning scheme effectively, a 3-class evaluation system including technical and economic aspects is established. A catastrophe theory based synthetical assessment on distributed network planning scheme is proposed. The proposed method adopts normalized formula to extract catastrophe progression under the assumption that the state variables near the critical point do not vary continuously. Therefore, it differs from ordinary methods in terms of using indices weights, so that subjective factors are avoided and decision obtained are more objective. Finally, the effectiveness and accuracy of the proposed method is verified by comparing with other methods on an actual distributed network.
