WOODWARD繼電模塊MRQ1系列介紹及選型
具有強(qiáng)大微控制器的數(shù)字保護(hù)繼電器
三角形連接中的三相電壓監(jiān)控
L1 相電流測量
字母數(shù)字顯示器便于設(shè)置保護(hù)繼電器、讀取測量值和計(jì)算值以及讀取故障存儲器
使用離散傅立葉分析對測量值進(jìn)行數(shù)字濾波,以抑制高次諧波和直流。由故障或系統(tǒng)操作引起的組件
通過兩個(gè)具有獨(dú)立設(shè)定點(diǎn)和時(shí)間延遲的低阻抗元件對同步電機(jī)的穩(wěn)定性特性進(jìn)行最佳調(diào)整
阻抗測量的指示:絕對值、實(shí)值和虛值
欠阻抗元件的欠壓閉鎖 (<10% Un) 以防止由于缺少測量電壓而導(dǎo)致的誤操作,例如保險(xiǎn)絲故障或發(fā)電機(jī)附近短路
自動調(diào)整采樣頻率,可在 40 Hz 和 70 Hz 之間進(jìn)行精確操作
外部閉鎖和復(fù)位輸入
通過串行接口 RS485 通訊
Digital protection relay with powerful microcontroller
Three phase voltage supervision in delta-connection
Current measurement in phase L1
Alphanumeric display for easy setting of the protection relay, reading of measured and calculated values and read out of the fault memory
Digital filtering of the measured values by use of discrete Fourier analysis to suppress higher harmonics and d.c. components induced by faults or system operations
Optimum adaptation to the stability characteristic of synchronous machines by two under impedance elements with separate set points and time delays
Indication of the impedance measurement: absolute, real and imaginary value
Under voltage blocking (<10% Un) of the under impedance elements to prevent maloperation due to missing measuring voltage, e.g. fuse failure or nearby short circuit of the generator
Self adjusting sample frequency for precise operation between 40 Hz and 70 Hz
External blocking and reset inputs
Communication via serial interface RS485
