Research conducted by our team focused on the development of a complete annealing unit, using modern technologies and components, such as a programmable logic controller, an industrial computer and microcontrollers, ensuring an intelligent way to control power semiconductor elements (SSR relays), with regard to minimizing retroactive effects on the supply network. This modern configuration offers a number of new possibilities of annealing unit control, including its remote control with the use of Internet connection. Another important part is the industrial PC with touch control. Together with the visualization system, it provides a comfortable environment for clear and simple input of parameters and commands to control the annealing process. Algorithms for two control methods were implemented, i.e. phase and full-wave control. The newly developed full-wave switching algorithm ensures an even distribution of performance with regard to load. Using this control method nearly eliminates retroactive effects of current harmonic components. Therefore, this newly developed annealing unit may also be used in public power distribution systems, as long as required compatibility standards are observed.
