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(jī)組臺數(shù)的確定常用柴油發(fā)電機(jī)組臺數(shù)的設(shè)置通常為2臺以上，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。

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(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，使發(fā)電機(jī)組仍然能夠滿足對重要用電負(fù)荷不間斷地持續(xù)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(jī)并機(jī)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(jī)組啟動，首先柴油發(fā)電機(jī)組自動合閘，當(dāng)此機(jī)組正常運(yùn)行后，另一臺機(jī)組自動根據(jù)母排電參數(shù)進(jìn)行追蹤同步合閘。并機(jī)后，各機(jī)組通過自動負(fù)荷分配器自動進(jìn)行負(fù)載分配及無功分配。啟動信號消失后，機(jī)組自動卸載停機(jī)。

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.
