Project description

INP International Projects was primarily awarded the contract to equip the Heidenheim CHP plant on the Voith factory premises with the Siemens PCS7 control system as the superordinate main control system (2 gas boilers, 5 CHP plants and all associated auxiliary systems).
In the course of the project, extensive adjustments were made to the machine and plant technology.
INP provided the complete redesign – including the replacement of outdated components, the integration of subordinate plant areas into the new control technology and the development of the necessary control algorithms for automatic operation. The plant was recommissioned on the basis of significant process engineering changes, such as the integration of a large-volume hot water storage tank, the replacement of steam boilers with hot water boilers and significant safety improvements to increase the degree of automation.

This means that, in future, economically viable operation can be achieved without permanent monitoring of the system.
Particularly noteworthy here is the implementation of the higher-level control system and the automatic operation system, which automatically operates the boiler, CHP units and the entire hot water and steam network. With the automatic heat- or electricity-controlled operation of the CHP plant, the system makes a decisive contribution to the district heating supply of the Voith plant and several companies located in Heidenheim.
