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 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。
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。
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,首先柴油发电机组自动合闸,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 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.
