With the original controls supplied, the generator controllers provide such features as local and remote starting, remote communications over custom networks and SCADA systems, multiple generator synchronizing and paralleling (load-sharing), generator to utility synchronizing and base-loading (load-govern), with varying limits on flexibility and valuable features. Most of the OEM solutions are designed to only interface with their own corporate built machines.
When the systems are upgraded to ComAp InteliGen, the system maintains all of the original upside, with many features and available flexibility not offered by the OEM.
So, obviously I am advocating ComAp and specifically the InteliGen, InteliSys and InteliMains products. One will ask why, so the highlights are as follows:
Taking a closer look at the control systems from the OEM:
Typical OEM controllers require a mixture of digital and analog interface wiring, over separate sub-systems, versus a control area network (CANBus). In a typical generator to utility paralleling installation some 30 individual conductors are needed for signal and control between each generator and the "master" control system, not to mention another 12 or so wires between the engine generator controllers. Then add in Modbus (232/485), Ethernet (TCP/IP), LonWorks and other "system networks" to the control wiring interface as well as network data converters and bridges.
Analog Wiring Control
Historically, the signal to share load, between machines, and control a load set-point against the infinite bus runs has been performed with analog bias wiring. This bias is highly susceptible to electrical interference (noise), voltage drop over wire length or dissimilar control voltages as well as technical and human error. CANBus control is not so heavily influenced and the technician error is non-existent.
Typical OEM control solutions do not employ a single platform control for both the generator, mains (utility), tie-breaker and feeder breaker control. What does this mean?
In closing, now is the time to consider an upgrade to your power system, power plant, distributed generation assets and even stand-alone machinery. We add value, features and functionality that simply isn't available from the manufacturer.
For the future, and your next power generation asset order, demand the ComAp solution upfront. Doing this will add features your system and make it very simple to incorporate changes without extra engineering services and complex system redesigns.
We offer solutions based services and provide the know-how to perform these conversions, and in several cases we have kit-solutions available to update and upgrade your generator controllers to ComAp.
