摘　　要：为了帮助配电自动化系统的规划设计,从投入产出角度对配电终端的最佳配置数量进行了研究;从供电可靠性的角度,对全部采用"三遥"配电终端、全部采用"二遥"配电终端、混合采用"三遥"配电终端和"二遥"配电终端、适当引入分界开关等情形下所需要的各类终端的数量配置进行了研究。研究结果表明:每条馈线配置1台配电终端的投入产出比最高,为满足供电可靠性要求,每条馈线所需配置"三遥"、"二遥"配电终端和分界开关的数量取决于要求达到的供电可靠性指标、人工故障区域隔离时间、故障修复时间和故障率。文中给出了一个含220条馈线的配电自动化系统规划实例,对所述方法的应用进行了详细的说明。To help with the planning and design of distribution automation systems （DASs）, the best amount of terminal units （TUs） mounted in a DAS is analyzed from the perspective of benefit/cost ratio first. From the perspective of reliability, the amount of various kinds of TUs in different situations is studied, that is only TUs with tele-control function, only TUs without tele-control function, a hybrid of TUs with tele-control function and TUs without tele-control function. Some circuit breakers with current protection mounted on some branches are investigated at length. The following conclusions are drawn that only one TU for each feeder is the best choice from the viewpoint of benefit/cost ratio, and that the demanded amount of various kinds of TUs depends on the reliability performance desired, the time of isolating the fault section by manual operation, the time of reparation, and the frequency of failure per-year. A DAS planning example with 220 feeders is given to illustrate the proposed methodology.
