Piller UK - CHP in Island Operation

UBT+ units - CHP - IP-System & solutions - Rotary UPS - Diesel Rotary Piller UK

Release the true potential from your CHP in Island Operation

Grid Stabilisation Case Study

Requirements

  • Site import capacity limited «4.5MW which is less than a third of maximum site demand
  • Attenuation of Fault current contribution to grid due to limited capacity in the local area
  • Integration of CHP to reduce emissions from plant utilising gas engines
  • Connection includes a 1MW export capacity allowance

Considerations

System integration must allow parallel operation with grid while limiting any potential fault current contributions but still allowing the export of excess generation.

The CHP utilises gas engines which require stable loads. The system application is a production facility with potentially large step loads which could cause instability issues and potential tripping.

System still to be able to function when in island mode to maintain stable operation of the gas engines without the stability of the grid.

Offer potential ride through to allow alternative embedded diesel generation to be used in the event of CHP failure.

Solution

2 x 2250kW Piller UBT+ units with 42MJ of ride-through energy operating within 11kV network as a parallel pair to offer power conditioning of the incoming supply, isolating harmonics and disturbances on the grid from the critical site supplies.

The UBT+ module integrates between the mains supply and the site generation. This offers a form of isolation between the site generation and grid achieving attenuation of faults between systems.

The stored energy within the UBT+ Kinetic Energy storage can be rapidly deployed via bi-directional converters to stabilise the frequency of the 11kV site network during loads steps in island operation. The technology allows for easy export of power while providing ultimate power protection to site critical loads with embedded gas generation.
