定子接地保護繼電器Applying relative arithmetic to all kinds of faults and calculating off - line, we can master time - distance relation chart for all kinds of faults. computation indicates : when transmission lines occur faults, the data window of protection algorithm consisting of prefault and postfault data at the same time has important significance. the following methods are useful to achieve the inverse time characteristic : calculating impedance by using flourier in a full cycle, calculating work voltage by using fault component, calculating the torque created by a phase comparator or a magnitude comparator
實際的計算表明:輸電線路發生故障后,用故障前後的數據同時充滿保護演算法的數據窗,對于快速切除近區故障具有很重要的意義;同時利用故障前後的數據,下述方法可以比較好地實現距離保護的反時限特性:直接用全周傅里葉演算法進行阻抗計算;採用工頻變化量阻抗繼電器進行工作電壓的計算;採用轉矩的思想進行轉矩的計算。Answer : preparative job includes : understands workplace one, the moving circumstance of 2 equipment, this job has with moving equipment without direct connection, have the job that cooperates without need with other team and group ; makes working priority discipline and the blemish that prepare to solve and weak point ; the staff member makes clear to divide the work and be familiar with the concerned data such as blueprint and test gauge cheng ; should be had the blueprint that agrees with actual state, record that examines last, newest rectify spare parts of the instrument that decides requisition, test gauge cheng, qualification, machine parts or tools kept in reserve, tool and join lead to wait ; is a few righter important equipment, especially complex protector or couplet jumps loop protector, should weave test program, working controller should fill in ticket of protection safety precaution, examine and approve via technical chief, just can carry out
答:預備的工作包括:了解工作地點一、二次設備的運行情況,本工作與運行設備有無直接聯系,與其他班組有無需要配合的工作;制定工作重點項目及預備解決的缺陷和薄弱環節;工作人員明確分工並熟悉圖紙與檢驗規程等有關資料;應具備與實際狀況一致的圖紙、上次檢驗的記錄、最新整定通知單、檢驗規程、合格的儀器、備品備件、工具和連接導線等;對一些重要設備,非凡是復雜保護裝置或有聯跳迴路保護裝置,應編制試驗方案,工作負責人應填寫繼電保護安全措施票,並經技術負責人審批,方能實施。Since that the choosing line hardware for the neutral ungrounded system has just passed part of the dynamic simulative test, matlab software was chosen to do a lot of simulative tests on single phase - to - grounding fault. and the simulative sampling ratio is almost the same as the hardware ' s. because there is a low wave filter in the hardware, i choose the db15 wave - let to carry out the multidimensional decomposition on the sample by the method of one dimension discrete wavelet in order to obtain low frequency signal including the high frequency transient information on single phase - to - grounding fault
鑒于實驗室已有的小電流接地系統選線硬體的研製只通過了實驗室里的動模試驗,故選用matlab軟體對小電流接地系統進行大量的單相接地故障模擬試驗,模擬的采樣率和硬體基本一致,由於硬體中帶有低通濾波器,故在進行采樣數據的morlet小波分析時先採用db15小波對采樣進行一維離散小波的多尺度分解,使得分解得到的低頻信號剛好包括了小電流接地系統單相接地故障時的暫態高頻信息,然後對這一信息再繼續進行小波演算法分析,分析結論表明利用變換后的實部、虛部和模值能夠較準確的實現單相接地故障時的故障選線和暫態高頻分量的提取。Author introduces the principle, the technical character and the technical data of the device. it is also advanced a scheme about catrier signal spanning the distribution line break. author provides the experiment report of the wfplc - m1 middle - voltage power line caner modem
