Abstract
M.Ing.
A performance indicator, such as the power efficiency characterisation, is used to
characterise many different systems and is a benchmark for efficiency
characterisation. Power is an instantaneous measure that only characterises a specific
operational condition of a system. Therefore, it is accurate and sufficient for characterising systems with (as far as possible) constant operational conditions that
do not fluctuate on a frequent basis. To characterise the overall performance of a
system with fluctuating operational conditions another method is required to
measure and calculate the overall system efficiency ...
