Genset speed control at NHS Hospital

Markets: Case studies for the Healthcare market
Application: Standby GeneratorsLocation: London, UKEngine: Perkins 4016 TAG4

IPU were recommended to the client for the required work by another of IPU’s customers. After experiencing problems with their original Woodward system, they needed a system that delivered the reliability they sought.


Challenges faced

The client reported major speed controlling issues with the original factory-fitted Woodward digital governor system. This left the hospital relying on a rented genset for 18 months for emergency standby power.

When IPU’s Engine Control engineers arrived on-site it was discovered the engine was one of the biggest built by Perkins: the 4016 TAG4. This turbo-charged V16, 61-litre engine uses common rail injection. It is at the limits of what can be controlled by electronic governing.


Solutions delivered

IPU supplied a GAC ACB2001 Actuator and an ESD5330 Electronic Engine Governor as the governing system. This system was powerful enough to control the genset successfully with no reported failures.

Follow-up checks verified that the genset had been operating correctly in STOR mode since October 2015, successfully exporting 1.1 MW of electrical power to the grid on a twice weekly basis with no reported failures.
