1. The capacity of common diesel generator set shall be determined according to the long-term continuous operation of the unit, the output power can meet the large calculation load selection of the whole project, and the reserve capacity of generator set shall be determined according to the importance of load. The continuous output power of diesel engine is generally 0.9 times of 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，以保證供電的連續性及適應用電負荷曲線(xiàn)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(jìn)行臺數，使柴油機經(jīng)常是在經(jīng)濟負荷下運行，以減少燃油消耗率，降低發(fā)電成本。

2. Determination of the number of common diesel generator sets the number of common diesel generator sets is usually more than 2 to ensure the continuity of power supply and adapt to the change of power load curve. Only when the number of generating units is large, can the number of generating units be determined according to the change of power load, so that the diesel engine often runs under economic load, so as to reduce the fuel consumption rate and reduce the power generation cost.

柴油機的佳經(jīng)濟運行狀態(tài)是在標定功率的75%-90%之間。為保證供電的連續性，常用機組本身應考慮設置備用機組，當進(jìn)行機組故障檢修或停機檢查時(shí)，使發(fā)電機組仍然能夠滿(mǎn)足對重要用電負荷不間斷地持續供電。

The best economic operation state of diesel engine is 75% - 90% of rated power. In order to ensure the continuity of power supply, the standby unit should be set for the common unit itself, so that the generator unit can still meet the continuous power supply for the important power load when the unit is overhauled or shut down for inspection.

柴油發(fā)電機并機模式下，如果控 制 器處于自動(dòng)狀態(tài)下，控 制 器收到啟動(dòng)信號后，各臺機組啟動(dòng)，首先柴油發(fā)電機組自動(dòng)合閘，當此機組正常運行后，另一臺機組自動(dòng)根據母排電參數進(jìn)行追蹤同步合閘。并機后，各機組通過(guò)自動(dòng)負荷分配器自動(dòng)進(jìn)行負載分配及無(wú)功分配。啟動(dòng)信號消失后，機組自動(dòng)卸載停機。

In the parallel mode of diesel generator, if the controller is in the automatic state, after the controller receives the start signal, each unit will start. First, the diesel generator unit will automatically switch on. When the unit is in normal operation, the other unit will automatically switch on synchronously according to the bus electrical parameters. After parallel operation, each unit automatically distributes load and reactive power through automatic load distributor. After the start signal disappears, the unit will unload and shut down automatically.
