1.常用柴油發(fā)電機組容量的確定按機組長期持續(xù)運行輸出功率能滿足全工程大計算負荷選擇，并應根據負荷的重要性確定發(fā)電機組備用機組容量。柴油機持續(xù)進行的輸出功率，一般為標定功率的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)電機組臺數的確定常用柴油發(fā)電機組臺數的設置通常為2臺以上，以保證供電的連續(xù)性及適應用電負荷曲線的變化。機組臺數多，才可以根據用電負荷的變化確定投入發(fā)電機組的進行臺數，使柴油機經常是在經濟負荷下運行，以減少燃油消耗率，降低發(fā)電成本。柴油機的佳經濟運行狀態(tài)是在標定功率的75%-90%之間。為保證供電的連續(xù)性，常用機組本身應考慮設置備用機組，當進行機組故障檢修或停機檢查時，使發(fā)電機組仍然能夠滿足對重要用電負荷不間斷地持續(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)電機并市電模式下，當市電停電時，市電開關自動跳閘，這時市電開關內送出一個市電失電信號和市電開關跳閘信號，同時到各臺機組的控制器上，如果控制器處于自動狀態(tài)時，控制器收到啟動信號后，延時幾秒鐘后（0-30S可調）啟動機組預供滑油系統(tǒng)，使機組預潤滑，再延時幾秒后（0-30S可調）啟動機組，各機組運行正常后，電壓、頻率都一致。臺機組自動合閘，另一臺機組經過自動同步追蹤系統(tǒng)自動追蹤，同步合閘，并網運行，機組并網成功后，各機組通過自動負載分配器自動進行負載分配。

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.

當市電來電時，市電轉換開關柜送出一個市電有電信號和市電開關合閘信號到各發(fā)電機控制器上，各發(fā)電機便分閘延時停機，從而實現自動開機、自動并網、自動卸載停機。

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)電機并機模式下，如果控制器處于自動狀態(tài)下，控制器收到啟動信號后，各臺機組啟動，臺機組自動合閘，當此機組正常運行后，另一臺機組自動根據母排電參數進行追蹤同步合閘。并機后，各機組通過自動負荷分配器自動進行負載分配及無功分配。啟動信號消失后，機組自動卸載停機。

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.
