Abstract
The thermal output of a combined heat and power generation system is regulated by varying the speed of rotation while maintaining the position of the control means of the thermal engine in its maximum efficiency range. For that purpose, the thermal engine in its full load position or efficiency optimum is brought to a lower or higher speed of rotation exclusively by respectively reducing or increasing the electric current fed into the mains, so that the efficiency of the thermal engine is not substantially affected. The electric current may be maintained at the desired frequency by frequency converters.
Claims5
A method for controlling a thermal output of a combined heat and power generation system having an internal combustion engine coupled to an electrical generator and load control means, the generator being electrically connected to en external net via an AC/DC/AC transformation by means of a frequency converter, the method comprising the steps of
- maintaining a throttle of the internal combustion engine in an essentially open position, and;
- controlling the amount of electric power discharged to the external net so as to vary the speed of rotation of the internal combustion engine in order to achieve a desired thermal output of the generation system.
