Human machine interface for a SCADA system applied on a district heating power plant

District heating is largely used today in many Romanian cities. But, having an efficient heating system on such a large area means introducing an adequate command, control and measuring system, too. Due to the continuous limitation of resources and also due to the high price of the energy, the measurement and the management of the heating agent is a real priority for the power plants and also for the heating distribution companies from Romania. There is a huge trend in the Romanian district heating industry to introduce as many as possible IT and TC solutions, or excellent measuring capacities. This paper presents human-machine interface, conceived by the authors and applied in the case of the small Power Plant located in Freidorf-Timişoara. Starting from computer science, computer graphics and thermal engineering, to electronics and electrical engineering as well ergonomy, this paper is a true example of a multidisciplinary research.
