基于可靠性的不同供电区配电自动化终端数量优化方案研究

Distribution Automation Terminal Optimal Scheme for Different Power-Supply Areas Based on Reliability

为了解决不同供电区对可靠性要求不同所导致的配电终端数量不同问题,提出了基于可靠性的不同供电区配电自动化终端数量优化方案,根据可靠性的要求提出配电自动化终端优化配置的思路和原则,分析了未实施配电自动化、全"二遥"、全"三遥"以及混合配置几种模式下的供电可靠性指标与配电终端数量之间的关系,并以某市级电网为例说明配电自动化终端优化过程,研究了配电自动化技术对供电可靠性的影响,以便更加合理科学进行配电自动化规划,并为今后配电自动化工程提供一定的参考。

To optimize distribution automation terminal, which meets the requirement of different power-supply areas, a scheme is proposed for distribution automation terminal optimal idea and principle for different power- supply areas based on reliability. It analyzes the relationship between the number of distribution automation terminal and supply reliability indicators in these cases： line without configuration of terminal unit, line with configuration of monitoring terminal unit only and line with mixed configuration of monitoring terminal unit and controlling terminal unit. A city-level network was taken as an example to analyze the effects of distribu- tion automation technology on power supply reliability and distribution automation terminal optimization process in order to provide more scientific and reasonable guidance over the distribution automation planning for the future automation projects.
