Configure Application > Configure Controller > Load Share Control
The easYgen utilizes a peer relationship between units to control
the system. This permits for parallel applications of up to 16 gener‐
ators.
Refer to Ä Chapter 3.3 "CAN Bus Interfaces"
on page 80 for information about the CAN bus connec‐
tion.
The parameter "Active load sharing factor" determines if and how a
generator performs real power or frequency control when paral‐
leled with other generators in an isolated operation. This parameter
is defined as a percentage.
In the figure below (Fig. 101) 10 % means increased real power
control and 99 % increased frequency control. This parameter
should be configured with the same value for each generator.
In the illustrated control system, it must be noted that each control
calculates the mean utilization factor of all controls from the data
transmitted via the CAN bus and then compares this with its own
utilization factor. The utilization factor is compared with the refer‐
ence variable and results in a new reference variable setpoint. Fre‐
quency and real power control are carried out simultaneously in
these controls (corresponding to the reference variable).
Frequency control is carried out via the measured voltage/fre‐
quency of the voltage system. The MPU is used merely for moni‐
toring functions, or is available as a control value to the secondary
controller.
