摘 要： 針對(duì)目前配網(wǎng)自動(dòng)化系統(tǒng)的饋線自動(dòng)化功能，提出了一種配網(wǎng)自動(dòng)化系統(tǒng)故障隔離和網(wǎng)絡(luò)重構(gòu)的整組試驗(yàn)方法。該方法能夠在配網(wǎng)自動(dòng)化系統(tǒng)運(yùn)行的配電線路上通過主、子站下傳帶時(shí)標(biāo)的模擬故障信息給控制終端，控制終端在規(guī)定時(shí)間點(diǎn)上傳解釋后的虛遙信，從而實(shí)現(xiàn)配網(wǎng)故障研判、隔離和重組。該方法在配電線路停電或運(yùn)行時(shí)均適用，停電試驗(yàn)或在線仿真試驗(yàn)簡(jiǎn)單、實(shí)用、高效，可作為配網(wǎng)自動(dòng)化系統(tǒng)饋線自動(dòng)化功能整組試驗(yàn)的通用試驗(yàn)方法。

Abstract: Aiming at the feeder automation function of the distribution network automation system, at present, this paper proposed a faultisolation and network-reconfiguration test method of distribution network automation system for the total group. This method could download the time-marked simulation fault information of distribution lines with the distribution network automation system and then sent them to the control terminals through master and slave station. The control terminal uploaded the explained virtual remote signals at the given time points, so as to realize fault analysis, fault isolation and restructuring of distribution network. This method applied in both outage and running distribution lines is proved simple, practical and efficient in power cut test or online simulation test, so that it can be used as a general test method of the total feeder automation function test for the distribution network automation system.
Key words: distribution network automation system; fault isolation; network reconfiguration; feeder automation test
