Figure: Load Demand Swapping example
The system is shown in previous figure. The InteliMains controller assumes the role of master in
priority swapping and swaps engine priority based on user defined power bands. There are 4 available
customizable power bands. The power band #5 is fixed – all available gen-set in power gen-set are
running.
Power bands are changed up if:
(Nominal power of all gen-sets in a particular band - Total generated power by gen-sets in power
management) < Reserve for start
or down if:
(Nominal power of all gen-sets in next lower band - Total generated power by gen-sets in power
management) > Reserve for stop
The site contains 3 gen-sets, G1 is 200kW, G2 is 500kW and G3 is 1000kW. The reserve for start is
adjusted to 50kW and for stop to 70kW. Following table describes available power bands:
