- The research of new type 1okv high - voltage phase comparator
高電壓相位測量儀 - Inside the integrated circuit ic1 , after suitable divisions , the two frequencies are sent to the phase comparator that generates the lock voltage of the secondary oscillator
在綜合電路ic1的內(nèi)部，經(jīng)過合適的劃分，兩個頻率被送往相位比較儀，這兩個頻率產(chǎn)生二級振蕩器的鎖電壓。 - 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(fā)生故障后，用故障前后的數(shù)據(jù)同時充滿保護(hù)算法的數(shù)據(jù)窗，對于快速切除近區(qū)故障具有很重要的意義；同時利用故障前后的數(shù)據(jù)，下述方法可以比較好地實現(xiàn)距離保護(hù)的反時限特性：直接用全周傅里葉算法進(jìn)行阻抗計算；采用工頻變化量阻抗繼電器進(jìn)行工作電壓的計算；采用轉(zhuǎn)矩的思想進(jìn)行轉(zhuǎn)矩的計算。
