Droop/Isochronous Load Sharing on an Isolated Bus 

Droop/Isochronous combines the first two modes. All generator sets in the 
system except one are operated in the droop mode. The one unit not in droop is 
operated in the isochronous mode. It is known as the swing machine. In this 
mode, the droop machines will run at the frequency of the isochronous unit. The 
droop and speed settings of each droop unit are adjusted so that each generates 
a fixed amount of power as illustrated in Figure 5-3. The output power of the 
swing machine will change to follow changes in the load demand. 

 

Figure 5-3. Droop/Isochronous Load Sharing 

 
 
Maximum load for this type of system is limited to the combined output of the 
swing machine the total set power of the droop machines. The minimum system 
load cannot be allowed to decrease below the output set for the droop machines. 
If it does, the system frequency will change, and the swing machine can be 
motorized. 
 
The machine with the highest output capacity should be operated as the swing 
machine, so that the system will accept the largest load changes within its 
capacity. 
 

Isochronous Load Sharing on an Isolated Bus 

Isochronous Load Sharing is the most common means of paralleling multiple 
generators together to a common load on an isolated bus. The EGCP-2 uses 
Isochronous Load Sharing control when operating in a Multiple Unit mode with 
the Load Control Mode in either Normal or Soft Transfer. Isochronous load 
sharing operates all generator sets in a system in the isochronous mode. Load 
sharing is accomplished by using the load sensor of the EGCP-2 to bias the 
speed reference of the isochronous governor. The EGCP-2 load sensors are 
connected by inter-control RS-485 network. In the case of the EGCP-2 control, 
Isochronous Load Sharing is done digitally via this network. Any imbalance in 
load between units will cause a change to the regulating circuit in each governor. 
While each unit continues to run at isochronous speed, these changes force 
each machine to supply a proportional share of power to meet the total load 
demand on the system.
