Adjust the delay if required (since the start of the engine
can take up considerable time, 0.5s should be sufficient)
Toggle on the protection for the interconnected VPIO input
(e.g. BI VPIO-1 1 is interconnected with BO VPIO-1 1)
Set the type of the
protection to Off load
Peak shaving based on Active and Apparent power (SPtM or SPI appl.)
The Peak shaving function is active only in AUT mode in parallel to Mains operation. Peak shaving is based
on Object P or Object Q (consumption of load). If load consumption increases over
ProcCtrlSingle:PeakLevelStart or ProcCtrlSingle:PeakKVAStart for period longer than
ProcCtrlSingle:PeakAutS/S or ProcCtrlSingle:PeakKVAS/S del the gen-set group is started (BO Sys
start/stop is activated). If load consumption decreases below ProcCtrlSingle:PeakLevelStop or
ProcessControl:PeakKVAStop for period longer than ProcCtrlSingle:PeakAutS/S del or
ProcCtrlSingle:PeakKVAS/S del the gen-set group is stopped. Both Peak shaving based on kW and kVA
can work simultaneously (SYS START/STOP is activated if at least one condition is fulfilled). Peak shaving
based on Apparent power is available in InteliGen-NT Basebox, InteliGen-NTC Basebox and InteliSys-NT
only.
