Because of the size of the load and the operating state of the generator set, it is sometimes necessary to use parallel machines. For example, in order to increase the flexibility of the backup power supply, or because the load is too large, two or more units can be considered for parallel use as the backup power supply. In some cases, due to the large proportion of inductive load in the load, the power required for startup is large, but the power is small during normal operation, resulting in low-load operation is very unfavorable to the unit, then consider using parallel startup load. , the mode of stand-alone operation after startup.
According to the size of the load, the unit will be automatically paralleled or disconnected and then shut down, so as to achieve better economic benefits and maintain a good operating state of the unit to achieve flexible power supply.
1. Parallel voltage type 50Hz: 380V-440V; 60Hz: 190V-240V, 380V-480V
2. The parallel capacity is large and the quantity is large. The minimum power is from 10 kVA -3800kVA. Up to 256 units
3. The power supply mode is flexible. The relevant number of units can be started and operated according to the actual load demand
