1.常用柴油发电机组容量的确定按机组长期持续运行输出功率能满足全工程大计算负荷选择，并应根据负荷的重要性确定发电机组备用机组容量。柴油机持续进行的输出功率，一般为标定功率的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.常用柴油发电机组台数的确定常用柴油发电机组台数的设置通常为2台以上，以保证供电的连续性及适应用电负荷曲线的变化。机组台数多，才可以根据用电负荷的变化确定投入发电机组的进行台数，使柴油机经常是在经济负荷下运行，以减少燃油消耗率，降低发电成本。柴油机的佳经济运行状态是在标定功率的75%-90%之间。为保证供电的连续性，常用机组本身应考虑设置备用机组，当进行机组故障检修或停机检查时，使发电机组仍然能够满足对重要用电负荷不间断地持续供电。

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.

柴油发电机并市电模式下，当市电停电时，市电开关自动跳闸，这时市电开关内送出一个市电失电信号和市电开关跳闸信号，同时到各台机组的控制器上，如果控制器处于自动状态时，控制器收到启动信号后，延时几秒钟后（0-30S可调）启动机组预供滑油系统，使机组预润滑，再延时几秒后（0-30S可调）启动机组，各机组运行正常后，电压、频率都一致。台机组自动合闸，另一台机组经过自动同步追踪系统自动追踪，同步合闸，并网运行，机组并网成功后，各机组通过自动负载分配器自动进行负载分配。

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.

当市电来电时，市电转换开关柜送出一个市电有电信号和市电开关合闸信号到各发电机控制器上，各发电机便分闸延时停机，从而实现自动开机、自动并网、自动卸载停机。

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.

柴油发电机并机模式下，如果控制器处于自动状态下，控制器收到启动信号后，各台机组启动，台机组自动合闸，当此机组正常运行后，另一台机组自动根据母排电参数进行追踪同步合闸。并机后，各机组通过自动负荷分配器自动进行负载分配及无功分配。启动信号消失后，机组自动卸载停机。

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.
