Operating cogeneration units with high availability

Small but safe power packs for domestic use

A combined heat and power unit (CHP) is a modular system for the extraction of electrical energy and heat. This is operated at the point of heat consumption. It is based on the principle of combined heat and power. Combustion engines, e.g. diesel, vegetable oil or gas engines, gas turbines and Stirling engines can all be used as drive for the power generator. As with generators, the electrotechnical monitoring is based on the insulation level or on the existing fault current, depending on the supply system (IT, TN). The frequency and the voltage also need to be within a specific range in order to be able to be fed into the general power grid.
