IHKW Heidenheim – Superordinate Main Control Technology
Location: Heidenheim, Germany
System/Technology: Siemens PCS7 incl. F-Systems
Services: Commissioning, Project management, Basic-engineering and pre-engineering, Detail engineering
Industry Branch/Type of Plant: Green Energy, Power Generation, Power plants
Client: EnBW
Project description
INP International Projects was awarded the contract to outfit the combined heat and power plant Heidenheim at the factory premises of the company Voith with the control system Siemens PCS7 as the superordinate main control system (2 gas boilers, 5 combined heat and power units as well as all associated ancillary equipment).
INP International Projects will also provide all of the scheduling here - with a dialog - of the existing S5 controls, the integration of superordinate S7 BlackBox controls in the new control technology as well as the re-commissioning of the system based on substantial technical changes and important control technology improvements intended to increase the degree of automation. In this way, an operation can be achieved in the future without ongoing monitoring. Of particular note here is the realization of the superordinate control regulation of the boilers, the CHP and the entire hot water and steam network for the automatic heating or current-controlled operation of the combined heat and power plant and thus the assurance of the district heating supply of the Voith plant as well as several companies based in Heidenheim.
