| 摘 要： | 配电自动化能够有效地提高供电可靠性，但必须兼顾其可靠性提升效益与投资之间的平衡。综合考虑可靠性和经济性，建立了实施配电自动化后的净收益模型。其中可靠性计算部分所采用的负荷点最小割集算法以及故障修复时间，均针对配电自动化条件进行了修正。结合国家电网公司规定的供电区域分类，研究了可靠性经济性最佳的差异性配电自动化方案。研究表明，B类供电区域推荐采用重合器与分段器配合的就地控制方案、分布式智能终端就地控制方案；产电比在15元/kWh以上的A类供电区域，推荐采用分布式智能终端就地控制方案。对于经济发达、负荷密度大以及可靠性要求高的地区，可考虑采用配电自动化主站集中控制方案，并给出了具体应用的产电比范围。

| Abstract: | Distribution automation can effectively improve power supply reliability, but the balance between efficiency and investment reliability must be taken into account. Considering the reliability and investment of distribution automation, this paper establishes the model of net income after the implementation of distribution automation, which contains an improved algorithm of minimum cut sets of load point and fault repair time mathematical model under the condition of distribution automation. Combined with the power supply area designated by the classification of State Grid Corporation of China, it puts forward the best distribution automation solution suitable for differentiation of each power supply division. Research suggests that in the area of B power supply, two kinds of distribution automation technology are recommended:feeder automation based on recloser and sectionalizer, intelligent control method based on distributed protection terminal. In the area of A power supply which the ratio of value to unit electric energy consumption is greater than 15, intelligent control method based on distributed protection terminal is recommended. For areas with developed economies, high load density, and high reliability requirements, distribution automation system is recommended and the range of the ratio of value to unit electric energy consumption is provided. |
