Detection of Diesel Generator Coupling Failure

Project Title: Detection of Diesel Generator Coupling Failure

Project Description:

A fault detection system is required for the drive coupling of an experimental 40kW diesel generator. Sensors for measuring the rotational speed of the unit are fitted on the generator, not the diesel engine. Consequently, in the event of the coupling shearing, as has happened previously, the plant control system causes the unit to overspeed. A statistical model is required of the engine speed that will be compared with the measured speed of the generator to check for excessive shear in the drive coupling.

Product Details:
A fault detection program will be developed that can be incorporated into the control system, and will initiate an emergency shutdown procedure in the event of coupling failure. Residuals of the model will be monitored with statistical process control tools to allow a distinction to be made between sensor noise and an assignable fault condition.

Resources Required:
PC + mathematical analysis software such as Matlab
