The control system of plants, which requires precise and reliable process information, has usually strong repercussions on efficiency and in thermal plants consequently on emissions. Virtual sensors are used for calculating system parameters, based on digital models of the corresponding parts of the plant. Starting with few state variables which can be defined or derive from trustful physical measurements, the virtual sensor system determines other desired parameters.
Especially if a large number of continues measurements are required, for example the measurements of gas flow in single pipes in a network, virtual sensors improve the accuracy and stability of the control system. A virtual sensor system can also provide fault detection to indicate defective physical sensors or leakages by supplying alternative values. Your further benefits are fewer costs for physical sensors and their maintenance in your system as well as the possibility to conduct virtual measurements in locations which are difficult to access.
