【摘要】：針對傳統(tǒng)單環(huán)網(wǎng)結(jié)構(gòu)無法滿足城市重點地區(qū)供電可靠性要求,同時雙環(huán)網(wǎng)結(jié)構(gòu)在舊城區(qū)難以實現(xiàn)的問題,提出基于環(huán)間聯(lián)絡和配電自動化的配電網(wǎng)設計方案。環(huán)間聯(lián)絡表示在2回電纜環(huán)網(wǎng)之間增設1路備用聯(lián)絡線的網(wǎng)架優(yōu)化方案。通過概率分布建模和計算,研究了環(huán)間聯(lián)絡線對負荷轉(zhuǎn)移能力的影響�？紤]聯(lián)絡線效用、重要負荷保障、投資建設成本3個因素,討論了聯(lián)絡線落點位置的選擇原則。為充分發(fā)揮環(huán)間聯(lián)絡結(jié)構(gòu)的負荷轉(zhuǎn)移能力優(yōu)勢,并降低故障處理時長,提出集中式和分布式協(xié)調(diào)配合的配電自動化設計方案,包括詳細動作邏輯。最后,基于樣本停電數(shù)據(jù)的可靠性分析結(jié)果驗證了本設計方案的有效性,并比較了網(wǎng)架結(jié)構(gòu)優(yōu)化和配電自動化各自的應用效果和投資回報率。
[Abstract]:Aiming at the problem that the traditional single ring network structure can not meet the demand of power supply reliability in the key areas of the city and that it is difficult to realize the double ring network structure in the old urban area, a distribution network design scheme based on interring connection and distribution automation is put forward. The connection between rings represents the optimal scheme of adding one standby tie line between the two loop networks. The influence of interring tie lines on load transfer capacity is studied by probability distribution modeling and calculation. Considering three factors, such as tie-line utility, important load guarantee and investment construction cost, the selection principle of landing location of tie-line is discussed. In order to give full play to the advantages of the load transfer capability of the inter-ring connection structure and reduce the time of fault processing, a centralized and distributed coordinated distribution automation design scheme, including detailed action logic, is proposed. Finally, the reliability analysis results based on sample outage data verify the effectiveness of the design scheme, and compare the application effect and return on investment of grid structure optimization and distribution automation.
