Abstract: The concept of co-generation means the combined production of electrical energy and of thermal energy based on the same primary energy source. The thermal energy can be used for heating, or for cooling. The real-time process control system, based on a modern architecture of software tools, is composed by classical algorithms running on a network of PLC-s and controlling algorithms implemented în a process computer. Some of them are typical numerical algorithms, and the others are adaptive control algorithms.

The purpose of the automatic control of the entire co-generative power plant is the optimization of the co-generative electrical energy provided in the national energy system and the thermal energy provided to the consumers.

Keywords: Electric power systems, real time systems, process control, optimization, control of distributed parameter systems, simulation, co-generative gas power plant.
