GENERATOR GRADIENT CONTROL
Ultracapacitor solution balances gradients and smooths genset power.
Benefits of the Skeleton solution
- VSG can achieve immediate response<20 msec on load variations with high gradients
- Engine can run at the most beneficial operating speed
- Increasedengine life through less wear and tear
- Uninterruptible power supplyin case engine is off
Challenge
High degree of random load variations
Background
- Random high load variationscan cause problems for Variable Speed
- Generators to continuouslysupply power with high gradients
Key challenges
- High degreeof random load variations
- Maintaining stabilityof power generation
- Operating efficientlyand improving fuel economy
- Longerrestart time
Known consequences
- Generator power gradients outside the limits
- VSG is not able to meet the load demand
- Shorterlifetime of engine
Solution
UCAP balance gradients and smooths genset power
What we offer
- Ultracapacitor solutionconnected to the DC link of power conversion system
- Ultracapacitors deliver necessary powerto compensate the load variations and smooth out genset power
- Ultracapacitors are the only viable technologyto provide high power and high duty cycle
