  (1) After the generator set is running normally, first adjust the voltage and frequency of the generator set to be roughly the same as the power grid, then place the synchronous measurement switch in the "well car" position and observe the synchronous meter;

  (2)、調(diào)整控制屏上的轉(zhuǎn)速微調(diào)電位器,使之與電網(wǎng)頻率相同,即同步表頻率差指示“Hz”指針處在中間略高位置:

  (2) Adjust the speed adjustment potentiometer on the control screen to be the same as the grid frequency, that is, the synchronous meter frequency difference indicator "Hz" pointer is slightly higher in the middle:

  (3) 、調(diào)節(jié)電壓整定電位器,使機(jī)組電壓與電網(wǎng)電壓相同,即同步表電壓差指示“V”指在中間位置。

  (3) Adjust the voltage setting potentiometer to ensure that the unit voltage is the same as the grid voltage, i.e. the synchronous meter voltage difference indicator "V" is in the middle position.

  注意:反復(fù)調(diào)整發(fā)電機(jī)組,并觀察同步表相位差指示“S”指針,使其緩慢順時針旋轉(zhuǎn)。當(dāng)指針旋轉(zhuǎn)接近垂直向上位置時,左手按下主開關(guān)合閘按鈕,右手?jǐn)嚅_同步測量開關(guān),主開關(guān)合閘并網(wǎng)發(fā)電。左手調(diào)整電壓整定電位器,將功率因數(shù)控制在滯后0.9-0.8之間,右手緩慢調(diào)整轉(zhuǎn)速微調(diào)電位器給機(jī)組加載。調(diào)整功率到合適位置(新機(jī)為60%Pe)最后將功率因數(shù)調(diào)整在0.8-0.9之間。

  Attention: Adjust the generator set repeatedly and observe the phase difference indicator "S" pointer on the synchronous meter to make it slowly rotate clockwise. When the pointer rotates close to the vertical upward position, press the main switch closing button with your left hand, disconnect the synchronous measurement switch with your right hand, and close the main switch for grid connected power generation. Adjust the voltage setting potentiometer with your left hand to control the power factor between 0.9-0.8 hysteresis, and slowly adjust the speed adjustment potentiometer with your right hand to load the unit. Adjust the power to the appropriate position (60% Se for the new machine) and finally adjust the power factor between 0.8-0.9.

  (4)發(fā)電機(jī)并網(wǎng)運(yùn)行中,應(yīng)注意觀察電器儀表及微機(jī)柜主控畫面各項參數(shù)的指示狀況,并根據(jù)技術(shù)要求,及時修正各項參數(shù)。

  (4) During the grid connected operation of the generator, attention should be paid to observing the indication status of various parameters on the electrical instruments and micro cabinet main control screen, and timely correcting various parameters according to technical requirements.

  (5)機(jī)組正常運(yùn)行中,每15分鐘作一次巡回檢查,觀察油溫、水溫、機(jī)油壓力、壓差、燃?xì)鈮毫八?、油位,每兩小時對機(jī)組參數(shù)作一次記錄。

  (5) During normal operation of the unit, a patrol inspection is conducted every 15 minutes to observe the oil temperature, water temperature, oil pressure, pressure difference, gas pressure, water level, and oil level. The unit parameters are recorded every two hours.
