OPTIMIZATION OF COLD STARTS IN THERMAL POWER STATIONS, IN PARTICULAR IN STEAM-ELECTRIC POWER PLANTS OR IN COMBINED CYCLE POWER PLANTS (CCPPS)
First Claim
1. A thermal power plant, comprisingan additional thermal energy storage device that is intrinsically in the power plant and is adapted to supply energy during starting up of the thermal power plant for heating components and/or media of the thermal power plant, andan additional electrical, chemical or mechanical energy storage device that is intrinsically in the power plant and is adapted to supply energy during starting up of the thermal power plant for feeding into an electrical energy distribution network.

Abstract
A thermal power plant, in particular to a steam-electric power plant or a combined cycle power plant (CCPP), and a method for operating a thermal power plant is adapted to accelerate, or to technically and/or economically optimize the start-up of the thermal power plant, in particular to accelerate/optimize a cold-start phase of the thermal power station. The thermal power plant has an auxiliary energy store integrated into the power plant. The store, during the start-up of the thermal power plant, delivers energy for heating/pre-heating components and/or media of the thermal power plant, or supplies an electrical power distribution network.

6. A method for operating a thermal power plant, comprising
during starting up of the thermal power plant, supplying energy by an additional electrical, chemical or mechanical energy storage device of the thermal power plant that is intrinsically in the power plant and that supplies the energy which is fed into an electrical energy distribution network during the starting up of the thermal power plant, and supplying energy by an additional thermal energy storage device of the thermal power plant that is intrinsically in the power plant and that supplies the energy with which components and/or media of the thermal power plant are heated during the starting up of the thermal power plant.
