The key process of the algorithm, called nodes transforming to arcs, is based on the calculation loads of coupling nodes and arcs loads from the loads of switch nodes. getting the area of coupling nodes is the most important process in nodes transforming to arcs. this paper presents a new method , which uses the adjacency matrix of distribution network and the information matrix of
變結構耗散網路是一種新的配電網自動化演算法,由配電網開關頂點負荷求弧負荷和耦合頂點負荷的點弧變換是整個演算法中確定配電網饋線故障區域的基礎,而進行點弧變換的關鍵就在於分離耦合點區域。In this thesis, we introduce the smart antennas and mainly examine the performance enhancements that can be achieved by employing sa in scdma wireless access system. in the part of introduction of smart antennas, we discuss the switched - beam arrays realizing by mending butler network at first. then we compare the different beam forming algorithms in sa
在對兩大類智能天線系統的介紹中,本文首先討論了一種以改進的butler網路實現波束賦形的多波束切換系統,推導了該天線陣的饋電模型並給出了模擬結果;然後,本文對智能天線波束形成演算法進行了比較,總結了不同演算法的優缺點,並給出具有代表性的演算法描述與模擬。But, the alarm signals from scada have disadvantages as follows : ( 1 ) the open - air feeder terminal units ( ftu ) are interfered by strong electromagnetic and thunder. besides, the failure of relays and the fault of ftu can also lead to that fault information is interfered and aberrant. ( 2 ) in the process of transmission and commutation, the error in the communication equipment may result in the signals err or lose
然而,現有的scada系統在配電網發生故障時提供給調度員的警報信息有如下局限性: ( 1 )面向現場的戶外饋線終端ftu運行環境惡劣,承受強的電磁、雷電干擾,並且由於繼電器節點故障、 ftu元器件損壞等因素的存在,使得配電網信息受干擾、畸變的可能性較高; ( 2 )在信號傳輸及變換過程中,通訊裝置的故障等原因,也可能導致信號出錯甚至丟失; ( 3 )保護裝置和斷路器本身也有可能誤動或拒動。Taking single four - quadrant power switch mode circuit as an example, the operational mode, steady principles, transient voltage feedback control strategy, the auxiliary switching power supply and parallel technology of this kind of converters are investigated. the output characteristic curve and the design for the key circuit parameters are given
