Method of controlling and regulating a power plant, and power plant for implementing the method

Abstract

In a method of controlling and regulating a power plant (50), in which power plant (50) thermal power is generated in a combustion chamber (35) from a gaseous fuel and the thermal power is at least partially converted into electrical power in conversion equipment (36), and in which power plant (50) the fuel for the combustion chamber (35) is produced in a fuel producer (31) from a feed product with the application of thermal and/or electrical power, which is removed at the outlet of the conversion equipment (36), and said fuel is passed on to the combustion chamber (35), optimal stability with a simultaneously wide control dynamic range are achieved in that the production of the fuel in the fuel producer (31) is stabilized by a first control loop (31, 51, 53, 60), and the conversion of the fuel into electrical power in the conversion equipment (36) is stabilized by a second control loop (36, 33, 55, 56, 58), and in that the power plant (50) as a whole is kept within a predefined operating range (a, b) by coupling the two control loops.
