초록 ▼

An electrical power generating arrangement (for example, in a combined heat and (CHP) system in is which fixed frequency AC electric power for supply to the mains or grid is output from a frequency converter supplied with a variable frequency AC power input from an electrical generator driven by an internal combustion engine. The speed of the engine is varied by operation of a throttle controlled by a controller containing a predetermined engine map representing variation of engine speed as a function of the variation in electrical power output from the frequency converter to meet the demand of an external electrical load. On the load demand changing, the controller signals the frequency converter to give a changed new power output to meet the changed demand. The controller consults the map to determine the new engine speed corresponding to the new power demand and operates the throttle to cause the engine to run at the new speed.

대표청구항 ▼

An electrical power generating arrangement from which an electrical power output is to be connected to electrical mains, said electrical power generating arrangement comprising: a reciprocating internal combustion engine; an electrical power generator rotatably driven by rotary drive from said reciprocating internal combustion engine; frequency converter means for converting variable frequency AC from said generator to a substantially fixed frequency AC for delivery to said electrical mains; and control means including an engine map for controlling an engine speed of said reciprocating internal combustion engine, for varying the engine speed as a function of the electrical power output to be delivered from said frequency converter means, and for operating in accordance with said engine map which represents the engine speeds as a function of the electrical power output from said frequency converter means, said engine map calculated using values of thermal power input to said reciprocating internal combustion engine and electrical power output from said frequency converter means to determine engine efficiency at varying engine speeds, said engine map providing a particular engine speed corresponding to a particular electrical power output from said frequency converter means, and said particular engine speed being an engine speed at which said reciprocating internal combustion engine is operating at substantially optimum efficiency to produce said particular electrical power output from said frequency converter means.
