Automation for the hydropower industry

In addition to primary technology, secondary technology is a key competence for a leading supplier of electromechanical products and services for hydropower stations.

In the same way as primary technology, power station automation is aimed at increasing output and decreasing costs. Whether it is newly constructed or modernized, each hydropower station requires specially adapted architecture meeting its specific requirements.

HYDRO offers modern automation solutions from an extensive portfolio

  • Automation & control
  • Excitation
  • Power plant management
  • Monitoring & diagnosis
  • Protection
  • Synchronization
  • Turbine governors

A milestone in the design of secondary technology solutions for hydropower plants was the creation of the integrated Neptun system. Neptun consists of all secondary equipment of a hydropower plant, from turbine governor, to excitation and protection systems, to local and superordinating automation and control systems. Close attention is paid to the systematic application of international standards and seamless system functions, while the individual requirements of stand-alone devices are also taken into account.

The advantages that customers gain from an integrated automation concept

  • Lower investment costs
  • Simplified start-up
  • Short standstill times during system replacements

Modernization and replacement projects must take the history of the station into account, which is reflected in different products, functions, cables, and sensors used over the different time periods. These projects typically require a step by- step approach. Modernizations as well as new construction of large systems are characterized by a large extent of complex hardware architecture, differing communication systems, and integration of the latest technologies. In small hydropower stations, cost-optimized hardware architectures with functional integration are typical features.

Each operational and maintenance concept takes a number of modern technologies and products into account. The global use of mobile phones, internet, and GPS are state-of-the-art. Any modern automation concept can utilize these technologies for optimization and simplification of maintenance.
