The Quality of Electric Power Supplied into the Grid by Co-Generation Units

Published by Jiri JANSA, Petr MOLDRIK, Daniel MINARIK, VSB – Technical University of Ostrava Abstract. This paper deals with the utilisation of firedamp for combined heat and electric power generation. The firedamp is gained from hard-coal mines and can be combusted in a co-generation units with gas-engine. This process involves more efficient utilisation of firedamp.Continue reading “The Quality of Electric Power Supplied into the Grid by Co-Generation Units”

Usage of Existing Power Plants as Synchronous Condenser

Published by Alexander DEECKE, Rafael KAWECKISiemens AG, Power and Gas, Instrumentation and Electrical Abstract. Due to the continuously increasing amount of renewable energy being generated and the simultaneous reduction in rotating masses, the demand for grid-stabilizing measures is growing. To solve the problem different possibilities are known, one of them is the reuse of fossileContinue reading “Usage of Existing Power Plants as Synchronous Condenser”
