【摘要】：隨著我國(guó)電力工業(yè)不斷發(fā)展,電力系統(tǒng)自動(dòng)化進(jìn)入了嶄新的發(fā)展階段。然而電力需求與電網(wǎng)設(shè)施不協(xié)調(diào)的局面仍然突出,特別是配網(wǎng)建設(shè)相對(duì)落后的情況尤為突出。為改變配網(wǎng)建設(shè)落后的現(xiàn)象,國(guó)家把農(nóng)網(wǎng)改造投資作為重要的投入方向。以此來(lái)改善配網(wǎng)的運(yùn)行可靠性,減少故障停電時(shí)間,為經(jīng)濟(jì)發(fā)展提供可靠的電力保障。配網(wǎng)自動(dòng)化建設(shè)是農(nóng)網(wǎng)改造的重點(diǎn)內(nèi)容,目前,配網(wǎng)自動(dòng)化系統(tǒng)的配置和實(shí)施原則更加強(qiáng)調(diào)監(jiān)測(cè)功能。在此背景下,如果能通過(guò)整合配網(wǎng)領(lǐng)域目前所應(yīng)用的各類信息系統(tǒng)資源,充分利用營(yíng)配信息集成系統(tǒng)現(xiàn)有數(shù)據(jù),對(duì)營(yíng)配信息集成系統(tǒng)中的配網(wǎng)線路拓?fù)浣Y(jié)構(gòu)、開(kāi)關(guān)設(shè)備屬性、分支線路的實(shí)時(shí)電流和配變電流負(fù)荷等信息進(jìn)行采集、分析、整合和過(guò)濾,開(kāi)發(fā)一款研發(fā)周期短,成本費(fèi)用低的智能輔助監(jiān)控軟件,實(shí)現(xiàn)對(duì)配網(wǎng)線路運(yùn)行狀態(tài)的準(zhǔn)實(shí)時(shí)監(jiān)控及智能告警功能,強(qiáng)化對(duì)各分支線路的管理,對(duì)解決配網(wǎng)盲調(diào)的問(wèn)題等具有重要的現(xiàn)實(shí)意義。本文以計(jì)量自動(dòng)化系統(tǒng)的實(shí)時(shí)負(fù)荷數(shù)據(jù)為基礎(chǔ),以營(yíng)配信息集成系統(tǒng)業(yè)務(wù)工單為依據(jù),研究在配網(wǎng)自動(dòng)化沒(méi)上線或終端監(jiān)測(cè)硬件設(shè)備覆蓋率不高的條件下配網(wǎng)線路(尤其是分支線路)故障停電的遠(yuǎn)程監(jiān)測(cè)及故障定位的輔助診斷方法,并且利用主配網(wǎng)拓?fù)淦唇印IS網(wǎng)絡(luò)拓?fù)渥粉櫵惴皢尉�圖動(dòng)態(tài)渲染技術(shù),充分利用營(yíng)配信息集成系統(tǒng)現(xiàn)有主配網(wǎng)拓?fù)淦唇�、�?jì)劃停電和有序用電業(yè)務(wù)數(shù)據(jù),集成主網(wǎng)SCADA10KV線路故障跳閘和計(jì)量自動(dòng)化電流負(fù)荷、配變失壓等實(shí)時(shí)監(jiān)測(cè)數(shù)據(jù),研究并建設(shè)配網(wǎng)線路遠(yuǎn)程監(jiān)測(cè)及故障診斷輔助功能,實(shí)現(xiàn)配電網(wǎng)線路故障停電的實(shí)時(shí)報(bào)文、語(yǔ)音告警和可視化展示,為解決長(zhǎng)期困擾供電企業(yè)配網(wǎng)故障發(fā)現(xiàn)晚、故障定位慢的問(wèn)題提供新的思路。
[Abstract]:With the continuous development of China's power industry, power system automation has entered a new stage of development. However, the situation of disharmony between power demand and power network facilities is still prominent. In order to change the backward situation of distribution network construction, the government regards the investment of rural power network transformation as an important input direction to improve the reliability of distribution network operation and reduce the time of power failure. The construction of distribution network automation is the key content of rural power network transformation. At present, the configuration and implementation principle of distribution network automation system emphasizes the monitoring function more. If we can integrate all kinds of information system resources used in the field of distribution network, make full use of the existing data of camp and distribution information integration system, and make use of the topology structure of distribution network and the attribute of switch equipment in the distribution information integration system, Collecting, analyzing, integrating and filtering the information of real time current and distribution current load of branch line, we develop an intelligent assistant monitoring software with short R & D cycle and low cost. To realize the function of quasi-real-time monitoring and intelligent alarm to the running state of distribution network, and to strengthen the management of each branch line, This paper is based on the real-time load data of the metrological automation system and on the basis of the business worksheets of the distribution information integration system. This paper studies the remote monitoring of distribution line (especially branch line) failure and the auxiliary diagnosis method of fault location under the condition that the distribution network automation does not go on line or the terminal monitoring hardware equipment coverage is not high. And using the main distribution network topology splicing GIS network topology tracing algorithm and single line graph dynamic rendering technology, making full use of the existing main distribution network topology splicing, planning power outage and orderly power consumption business data, the existing main distribution network topology splicing, the planned outage and the orderly power consumption business data are fully utilized in the camp distribution information integration system. By integrating the real-time monitoring data of SCADA10KV line fault tripping and automatic current load measurement, distribution transformer voltage loss and other real-time monitoring data, the auxiliary functions of remote monitoring and fault diagnosis of distribution network line are studied and constructed to realize the real-time message of distribution network line fault outage. Voice alarm and visual display provide a new way of thinking for solving the problem of late fault discovery and slow fault location in power supply enterprises for a long time.
