The objective of this thesis is presentation of work on project of the realization of control of cogeneration system for Slovenian energy company. On this project I was working as programmer for automatization of cogeneration system. In the thesis I will present realization of project goals. Goals were PLC programming, implementation of supervisory system and preparation of project documentation.
In the first part of the thesis I will present theoretical points of cogenerations, components for automatization and used communication protocols. Theoretical part is based on available literature.
In the second part of the thesis I will describe realization of control and present supervisory (SCADA) system that I made. For this project goals were to program a control of cogenerator power and boiler using Siemens S7-1200 controller. In the system of cogeneration sensors are used for measurement of system parameters, that are used for calculation of system efficiency and control parameters.
