1.常用柴油發(fā)電機(jī)組容量的確定按機(jī)組長(zhǎng)期持續(xù)運(yùn)行輸出功率能滿足全工程大計(jì)算負(fù)荷選擇，并應(yīng)根據(jù)負(fù)荷的重要性確定發(fā)電機(jī)組備用機(jī)組容量。柴油機(jī)持續(xù)進(jìn)行的輸出功率，一般為標(biāo)定功率的0.9倍。

1. The determination of the capacity of commonly used diesel generator sets should be based on the long-term continuous operation output power of the unit to meet the large calculation load selection of the entire project, and the reserve unit capacity of the generator set should be determined based on the importance of the load. The continuous output power of a diesel engine is generally 0.9 times the rated power.

2.常用柴油發(fā)電機(jī)組臺(tái)數(shù)的確定常用柴油發(fā)電機(jī)組臺(tái)數(shù)的設(shè)置通常為2臺(tái)以上，以保證供電的連續(xù)性及適應(yīng)用電負(fù)荷曲線的變化。機(jī)組臺(tái)數(shù)多，才可以根據(jù)用電負(fù)荷的變化確定投入發(fā)電機(jī)組的進(jìn)行臺(tái)數(shù)，使柴油機(jī)經(jīng)常是在經(jīng)濟(jì)負(fù)荷下運(yùn)行，以減少燃油消耗率，降低發(fā)電成本。柴油機(jī)的佳經(jīng)濟(jì)運(yùn)行狀態(tài)是在標(biāo)定功率的75%-90%之間。為保證供電的連續(xù)性，常用機(jī)組本身應(yīng)考慮設(shè)置備用機(jī)組，當(dāng)進(jìn)行機(jī)組故障檢修或停機(jī)檢查時(shí)，使發(fā)電機(jī)組仍然能夠滿足對(duì)重要用電負(fù)荷不間斷地持續(xù)供電。

2. Determination of the number of commonly used diesel generator sets The setting of the number of commonly used diesel generator sets is usually at least 2 to ensure the continuity of power supply and adapt to changes in the electricity load curve. Only with a large number of units can the number of units put into operation be determined based on changes in electrical load, so that diesel engines often operate under economic loads to reduce fuel consumption and power generation costs. The optimal economic operating state of a diesel engine is between 75% -90% of the rated power. To ensure the continuity of power supply, backup units should be considered for commonly used units themselves. When conducting unit troubleshooting or shutdown inspections, the generator set can still meet the uninterrupted and continuous power supply for important electrical loads.

柴油發(fā)電機(jī)并市電模式下，當(dāng)市電停電時(shí)，市電開關(guān)自動(dòng)跳閘，這時(shí)市電開關(guān)內(nèi)送出一個(gè)市電失電信號(hào)和市電開關(guān)跳閘信號(hào)，同時(shí)到各臺(tái)機(jī)組的控制器上，如果控制器處于自動(dòng)狀態(tài)時(shí)，控制器收到啟動(dòng)信號(hào)后，延時(shí)幾秒鐘后（0-30S可調(diào)）啟動(dòng)機(jī)組預(yù)供滑油系統(tǒng)，使機(jī)組預(yù)潤(rùn)滑，再延時(shí)幾秒后（0-30S可調(diào)）啟動(dòng)機(jī)組，各機(jī)組運(yùn)行正常后，電壓、頻率都一致。臺(tái)機(jī)組自動(dòng)合閘，另一臺(tái)機(jī)組經(jīng)過自動(dòng)同步追蹤系統(tǒng)自動(dòng)追蹤，同步合閘，并網(wǎng)運(yùn)行，機(jī)組并網(wǎng)成功后，各機(jī)組通過自動(dòng)負(fù)載分配器自動(dòng)進(jìn)行負(fù)載分配。

In the mode of diesel generator combined with mains power, when the mains power is cut off, the mains power switch automatically trips. At this time, a mains power loss signal and a mains power switch trip signal are sent from the mains power switch, which are simultaneously sent to the controllers of each unit. If the controller is in automatic mode, after receiving the start signal, the controller will delay for a few seconds (adjustable for 0-30S) to start the pre supply lubricating oil system of the unit, After a few more seconds of delay (adjustable for 0-30S), start the unit. After each unit operates normally, the voltage and frequency are consistent. Firstly, the first unit automatically switches on, while the other unit is automatically tracked, synchronized, and connected to the grid through an automatic synchronous tracking system. After the unit is successfully connected to the grid, each unit automatically distributes load through an automatic load distributor.

當(dāng)市電來電時(shí)，市電轉(zhuǎn)換開關(guān)柜送出一個(gè)市電有電信號(hào)和市電開關(guān)合閘信號(hào)到各發(fā)電機(jī)控制器上，各發(fā)電機(jī)便分閘延時(shí)停機(jī)，從而實(shí)現(xiàn)自動(dòng)開機(jī)、自動(dòng)并網(wǎng)、自動(dòng)卸載停機(jī)。

When the mains power comes on, the mains power conversion switch cabinet sends a mains power signal and a mains power switch closing signal to each generator controller, and each generator opens and delays shutdown, thereby achieving automatic startup, automatic grid connection, and automatic unloading and shutdown.

柴油發(fā)電機(jī)并機(jī)模式下，如果控制器處于自動(dòng)狀態(tài)下，控制器收到啟動(dòng)信號(hào)后，各臺(tái)機(jī)組啟動(dòng)，臺(tái)機(jī)組自動(dòng)合閘，當(dāng)此機(jī)組正常運(yùn)行后，另一臺(tái)機(jī)組自動(dòng)根據(jù)母排電參數(shù)進(jìn)行追蹤同步合閘。并機(jī)后，各機(jī)組通過自動(dòng)負(fù)荷分配器自動(dòng)進(jìn)行負(fù)載分配及無功分配。啟動(dòng)信號(hào)消失后，機(jī)組自動(dòng)卸載停機(jī)。

In the diesel generator parallel mode, if the controller is in automatic mode, after receiving the start signal, each unit will start. The first unit will automatically close. When this unit operates normally, the other unit will automatically track and synchronize the closing based on the electrical parameters of the busbar. After the parallel operation, each unit automatically distributes load and reactive power through an automatic load distributor. After the start signal disappears, the unit automatically unloads and stops.
