Mission-critical Multiple Gen-sets Standby

In datacenters, hospitals, banks or other mission-critical installations, the security of the power supply plays a key role. Every second of power loss may have severe consequences. Therefore, N-1 or even higher redundancy criteria is a requirement, to insure that the power will, in all circumstances, be provided for the vital functions of the installation.


The mains power in mission-critical installations is often supplied through two or more mains incomers to 'keep the lights on' even in case of an incomer failure or planned maintenance. However, failures of the superior power distribution system can never be avoided, therefore standby generators are used as a standard solution. These mission-critical sites are complex installations and it is not allways easy to fulfill the requirements, therefore the system and its components need to be very flexible, allowing the system designers space for the correct engineering solution. As long as the standby system is expected to run in islanded mode, redundancy and remote supervision is a must.

ComAp Solution

ComAp’s InteliGen NT and InteliSys NT controllers offer large scale of very complex features. A large choice of auxiliary I/O modules, communication and monitoring capabilities and a intuitive user and configuraiton interface empower engineers to face even the most challenging requirements of security of power supply in mission-critical applications. SCADA, configuration, and commissioning tools or fleet monitoring through WebSupervisor make ComAp the first choice for mission-critical solutions.

Mission-critical Multiple Gen-sets Standby
  1. Application for faster start-up sequence of multiple generators. No need to synchronize generators by standard way and wait until all of them are synchronized on the same bus.
  2. Suitable for standby applications, eliminates possible blackout time, ideal for systems running on UPS.
  3. System available at full capacity in 8-10 seconds from start command. Start-up time remains constant even if the number of generators is increased to 10, 20 or 31.
  4. To avoid delaying availability of the system due to slow-starting generators or other problems, any engines that fail to reach running speed within a specified time are “rejected” from the scheme and, if able, are left to perform traditional synchronizing after the majority of sets have become available.
  5. Traditional synchronizing available to allow for slow-starting generators. Automatic switching to traditional synchronizing in case insufficient sets are available to meet load’s requirements.
  6. The soft magnetizing of feed transformers – solves the problem where grid supply is not capable of supplying the inrush and decreases the overall cost of the installation.
