ABSTRACT:
An electrical power generating arrangement (for example, in a combined heat and power system) in which electric power for supply to mains or grid is output from a generator driven via a continuously variable transmission (C.V.T.) by an internal combustion engine having a throttle. The throttle opening and ratio of the C.V.T. are controlled by a controller comprising a computer programmed with an engine map which is consulted by the computer when there is a change in an external electrical load power demand. For any load, the map indicates at which speed the engine should be run for optimum engine efficiency, the throttle opening is varied to attain that speed, and the controller varies the ratio of the C.V.T. to a value consistent with the desired engine speed.
