雷電流參數的測量是進行雷電研究的基礎工作,對于研究雷電特性、分析雷害事故、鑒定雷擊跳閘事故責任、探討防雷對策及為絕緣配合設計提供精確的大氣過電壓原始數據均具有十分重要的意義。After that, the author discusses a novel solid states limiting technology and provides a single - phase solid states bridge current limiter and a main circuit topology of three - phase fault current limiter. it can be found that the new type of three - phase solid states bridge current limiter can handle the fault conditions more flexibly. it can not only remove the fault circuit, but also control the value of stable fault current to cooperate with the existing line three - segment relay
繼而,介紹了一種新型固態限流技術,給出了單相、三相限流器的主電路拓撲,分析了其基本工作原理和控制方式,指出以全控橋結構為基礎的變壓器耦合橋式限流器能夠更加靈活地處理電力系統的各種短路故障,及時地限制短路電流,並與現有的線路三段保護相配合,還可根據需要實現及時切除故障電路,在故障恢復時軟重合閘。The concept of minimum distribution part ( mdp ) is put forward together with the adjacent table based method to divide a distribution network into several mdps. based on above theory ; a novel way to identify fault sections of a distribution network is presented. algorithm to isolate the fault section with minimum switch operations and identifying of over - tripped switches are discussed
提出最小配電區域的概念,並基於等長鄰接表的數據結構建立了最小配電區域分解的方法,在此基礎上發展了一種新穎的配電網故障區域判斷和隔離方法,研究了以最少的開關操作隔離故障區域的方法和越級跳閘開關的判斷問題,探討了針對採用重合分段器的配電網故障區域判斷和隔離問題。It is the important research subject in sluice design and analysis currently that modeling rapidly and accurately in sluice fem analysis in condition of weak foundation, nonlinear simulation analysis of sluice and auto steel design
軟土地基上水閘有限元分析的快速準確建模、非線性模擬分析及自動配筋設計是水閘設計和分析中的重要研究內容。An objective function is made using the trade - off between transportation and facility costs, within this model, the user equilibrium assignment procedure is used for determing truck and passenger car traffic on the road network under any location pattern of candidate sites of public logistics terminals
由於物流基地的選址與城市交通網路有密切的關系,因此文章在第4章著重閘述了城市交通網路的流量分配問題,主要是在用戶平衡條件下的四種流量分配形式。The study result that there is slightly stress concentrated in the aera of the dam which with opened hollow and pier added. by the tension stress is more over the design intension, we need more reinforcement to resisted the stress
結果表明在孔口和閘墩附近出現了程度不太嚴重的應力集中現象,但拉應力超出抗拉設計強度較多,有必要採取配筋等措施來抵抗動力作用下的拉應力。This thesis presents a single - terminal fault location technique that is used together with recloser. the technique takes advantage of reclosing of single - terminal recloser to eliminate the influence of the remote source impedance. a distributed parameter line model is used for the proposed algorithm, thus the technique can be used in hv transmission line
為了克服這一缺點,本文提出了與自動重合閘配合使用的單端故障測距方法,根據電力系統的運行特點,利用故障線路在試送電時自動重合閘的單端重合狀態來消除對端系統的影響,測距演算法建立在分佈參數模型基礎上,使其可應用於高壓輸電線路。Through analysis and study, it is believed important and feasible that the implemented projects, the importing feng jia - shan reservoir into yang mao - wan reservoir and the water supply from shi tou river to xi ' an city ; form the synthetic analysis of the main factors - quantity, time, apace and user " character, it can be conferred that it is not necessary for the four projects in the western areas to join together at present ; adding gate at the 2 head of lin jiacun trench can only help to relax the problem of lack of water in bao jixia irrigation area, to solve the problem of short of water in the irrigation area needs to take project measures at the trunk and branches of wei he river from lin jia village to the upper stream ; the mode of supplying water of the four projects in the western areas are all by gravity, they can only be supplied one way and ca n ' t be supplied each other
通過分析研究認為:已實施的引馮濟羊工程和石頭河西安供水工程,是十分必要的和可行的;從水資源配置的主要要素? ?數量、時間、空間和用戶性質的綜合分析研究來看,西部四大工程目前尚無整體聯網的必要;林家村渠首加閘對解決寶雞峽塬上灌區缺水僅能起到緩解作用,從根本上解決塬上灌區的缺水問題,還必須從林家村以上渭河干支流上採取進一步的工程措施;西部四大工程均為重力供水,只能單補,而不能互補。In addition, each rectifier arm was made of many thyristors that are parallel connection, so there had the problem that current was distributed equably, in the same way, current - sharing coefficient was a vary important technology index
另外,每一個整流臂由多隻晶閘管並聯而成,這樣就存在電流均勻分配的問題,均流系數同樣是一個非常重要的技術指標。分享友人
