ICRA has designed and installed a system for data acquisition in power plants via computer. Values for the production of electricity, gas and communal heating are processed in real-time taking into account weather data (in Phase I) as an input to model and trend calculations for peak loads with display in colour in the control rooms. It proposes increase / decrease of energy production via data loggers in phase II. A closed-loop control of the power supply station(s) is intended in phase III.
