With Scientific Automation, Beckhoff seamlessly combines the functionality of conventional control technology such as PLC, motion control and automation technology, with precise and fast measurement technology and engineering algorithms. The scientific automation can be implemented on a standard, integrated platform and, thanks to the modularity of the systems, optimally adapted to the respective application and easily expanded at a later stage. The scientific automation solution provides users with a compact and cost-effective alternative to make energy consumption highly transparent. This in turn is a prerequisite for maximising energy efficiency and can serve as the basis for future smart-grid applications.
The stations become devices in the data network of a smart grid through the flexible expandability of the PC-based control technology. Integrated energy measurement enables users to extend energy and state monitoring with remote control protocols. The integrated measurement systems, in office buildings, factories, substations in a distribution grid, wind farms, cogeneration or biogas plants, can be made ‘smart’ with retrofits. In this way, an office building can generate negative balancing energy by means of a heat pump ‘charging’ a heat store, for example. Positive balancing energy could be generated via a stand-by unit that is activated by the grid operator. Integrated energy measurement is capable of realising this kind of balancing energy at sites that are configured as virtual power stations and equipped with embedded PCs.
- Industrial productivity has increased to a level where the potential for further improvements is limited.
- Energy efficiency offers that potential for improvements.
- Scientific automation - the integrated energy measurement approach - opens up larger potential for efficiency improvements.
