A novel distribution network optimal control approach for load balancing is presented based on the simplified model of distribution system , in which tie switches are regarded as critical elements . the two feeder lines connected with a tie switch are regarded as a feeder couple . load balancing ratios of feeder couples and total distribution network are defined and be used as indice of network reconfiguration , respectively 提出一種以聯絡開關為核心的用于負荷均衡化的配電網絡優化控制方法,將每個聯絡開關對應的兩條饋線看作饋線偶,定義了饋線偶和配電網的負荷均衡率,并以此作為網絡優化的評價函數,這樣配電網絡重構過程就由若干饋線偶內負荷均衡化過程組成,在此基礎上發展了以負荷均衡化和降低線損為目標的配電網優化方法。

Emphasis on picking up node failure message characters and matrix based on topology fabric and abutment matrix via switch node , analyzing the distribution feeder line break - down at single circumstance , discussing the distribution feeder line break - down judgment matrix , judge out the breakdown area of the segment through analyzing the break - down matrix inside chemical elements 論文軟件著重研究了以配電網拓撲結構以及開關為節點的鄰接矩陣為基礎、在實時情況下,提取電網節點故障信息特征及矩陣,舉例說明了通過分析配電網饋線單一故障情況,利用饋線網絡故障時的故障區段判斷矩陣,通過分析故障判斷矩陣中元素的性質,來判斷出故障區段的方法。

The detailed examples are also given to illustrate the flow of single kanban system between packaging line and warehouse and dual kanban system between final assembly line and feeder line . finally , the kanban rules and comparison between single kanban and dual kanban are discussed from the practical point of view the calculation of number of kanban is presented quantitatively 分析在生產輔助線各工序之間的物流和單、雙向看板;并通過詳盡的事例及圖解闡述打包線和倉庫之間的單向看板流程和總裝線與生產輔助線之間的雙向看板系統;最后,從實際觀點出發來討論單向及雙向看板之間的規則和比較。

A simplified analysis method of distribution networks is presented . the voltages and the power on / through both end of the feeder are used to describe the load and its distribution within the feeder line . only field test datas from feeder circuit breakers in substations , switches along the feeder lines and on the loop points are needed to obtain a sactisified analysis result 提出一種通過饋線兩端的電壓和流過饋線兩端的開關的功率反映饋線上的負荷及其分布情況的配電網的簡化分析方法,這種方法只需對變電站的出線開關、饋線的分段開關和聯絡開關進行量測,而不必量測饋線上的配電變壓器,就能得到滿意的分析結果。

A new model of distribution system is presented , whereby , the feeder switches are regarded as the vertcxes of a graph and the feeder lines are regarded as the arcs . the method to model distribution networks by adjacent table is put forward . therefore , storage size is reduced and calculation is speeded up 建立了配電網的簡化模型,即將饋線開關當作圖的頂點、將饋線當作弧,采用等長鄰接表的數據結構來描述配電網,大大減少了占用空間和提高了查詢速度,并建立了基于等長鄰接表的配電網絡拓撲算法。

According to the amended industrial catalog guiding foreign investment approved by the state council at the beginning of this year , all railway projects , including manufacturing of railway transport equipment , and construction and management of feeder lines , local railways , and related bridges , tunnels and ferries , fall into the category encouraged by the state 根據國務院批準、今年初實施的《外商投資產業指導目錄》規定:所有的鐵路項目如鐵路運輸設備制造、支線、地方鐵路及其橋梁、隧道、輪渡設施的建設和經營,都屬于鼓勵范圍。

In oilfield , feeder line of 6kv often has many branches . the pole high voltage automotive capacitor compensation system controlled by single chip computer is designed for this situation . in the system , we separate the measure position and compensation position and realize the supervision of reactive load in local area 文章以油田6kv輸配電線路為例,針對多分支樹狀結構線路的特點,研制出由單片機系統控制的戶外術上型高壓電容器自動補償系統。

After analyzing several kinds of protection for feeder line in subway dc traction power supply system , it is pointed out in the paper that the phenomena of refusing action and error action can not be avoided with existing protection which can not protect the whole feeder line 摘要分析了地鐵直流牽引供電系統中幾種常用的饋線保護類型,發現現有的保護方法很難避免跳閘保護拒動或誤動現象的發生,并且不能保護饋線的全長。

Possessing special feeder lines and a fleet of container trucks , we can receive export and import cargoes transported by reailway , and provide services as discharging , dispatching , distribution and transiting etc . in shanghai or to all places of china 擁有鐵路專用線、集裝箱運輸車隊,可承辦鐵路進出口貨物進站、交接、裝車發運、分撥轉運等業務及進出口貨物的市內運輸和跨省市貨物的轉運。

As a major mode of transport in the northwest new territories , the light rail has become a feeder line for the newly opened west rail . commuters can travel for free on the light rail if they transfer to the west rail 在西鐵啟用后,輕鐵成為西鐵的接駁交通工具,如乘客乘輕鐵轉駁西鐵,則輕鐵的一程可享免費優惠。

In the simplified model the feeder switches are regarded as the vertexes and the feeder lines as the arcs of a graph 簡化模型把配電網描述為有權的節點和弧的圖,在此基礎上進行故障的定位、隔離和恢復處理。
