| 摘要: |
| 提高配电系统供电可靠性是智能电网建设的重要目标，由于受多种因素的影响，供电企业为了提高配电网供电可靠性的投资行为具有较大的风险。在阐述了配电自动化系统的基本原理和结构特点的基础上，提出了配电自动化系统可靠性成本效益综合分析模型。结合配电系统可靠性的工程计算方法，通过对配电自动化系统在提高系统供电可靠性方面的成本和效益进行定量计算，结合正态云理论对配电自动化系统改造方案进行经济性评估，定义了多个综合评价指标，为电力管理工作者提供智能决策支持。通过对一个实际的配电系统进行计算分析，表明该模型具有较好的实用性和可行性。 |

| Abstract: |
| To improve the power supply reliability of distribution system is an important goal of smart grid construction. Due to various influencing factors, it is of great risk for the power supply enterprise to invest in improving the distribution network power supply reliability. By elaborating the basic principles and structure characteristics of the power distribution automatic system, a new cost-benefit analysis model for reliability of distribution network automation is presented. Combined with the engineering calculation method for distribution system reliability, the quantitative calculation of the costs and benefits of improving distribution system reliability is conducted, the economic evaluation of the modification scheme for distribution automation system is made based on normal cloud theory, and multiple comprehensive evaluation indexes are defined, which provides intelligent decision support for power management layer. An actual distribution system example analysis shows that the model has better practicability and operation. |
