It is necessary to study the mechanism of harmonics generation, make sure the content and distribute of harmonics current in order to alleviate their harm to traction power system ' s component, equipments of protect and measure as well as other customer ' s electronics equipments
為了從根本上抑制電力牽引負荷諧波帶來的影響，削弱諧波對牽引供電系統主元件、保護測控裝置和其他用戶電子設備的影響，有必要研究電氣化鐵道牽引諧波產生的機理，確定饋線電流諧波的含量與分佈狀況。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。A differential relay is a protective device that is fed by current transformers located at two different series points in the electrical system
差動繼電器作為保護裝置，差動繼電器由位於系統中兩個不同位置的電流互感器提供反饋信息。Differential relay a differential relay is a protective device that is fed by current transformers located at two different series points in the electrical system
差動繼電器作為保護裝置，差動繼電器由位於系統中兩個不同位置的電流互感器提供反饋信息。Ftu can complete the detection and position of the breakdown independently. so it greatly reduces the cost of das construction investment and the communication channel maintenance. at the same time, it also reduces the dependency of communication channel level, enhances the reliability of the feeder automatization
該方案最大的特點在於ftu裝置採用無通道保護技術，沿饋線分佈的ftu裝置之間不需要架設通信通道， ftu裝置本身就能獨立地完成故障的檢測和定位，大大降低了配電自動化系統的建設投資成本和運行中對通信通道維護費用，同時也減少了對通信通道的依賴程度，提高了饋線自動化系統的運行可靠性。分享友人
