Solutions for Advanced Process Control

Complex Challenges

The requirements to conventional power plants have risen in recent years. This has led to new and complex challenges regarding efficiency increase and profitability.

Some of the particular challenges are:

  • Changing coal types on the world market
  • Load sequence requirements by feeding renewables
  • Higher availability and service life

Intelligence for process control  

These and other challenges can be managed by increased process monitoring in combination with intelligent process management.

Not just the sum of the experiences

Intelligence results from experiences. When further experiences are added to the knowledge already acquired, intelligence grows. Therefore System Technologies has developed a software that learns constantly, that autonomously finds the overall optimum in the process and continuously and autonomously adjusts its strategy to it. Acquired knowledge is saved and adjusted to process changes self-sufficiently without further external support. This allows for intelligent and fast reactions.

Increased efficiency by intelligent optimization

  • Increasing the process monitoring and thus improving the descriptiveness of the process
  • Continuous control of the local fuel/air ratios depending on fuel qualities, mill status, and boiler status
  • Autonomously self-adjusting and continuously improving control strategy
  • The result: increased efficiency with less undesired effects due to improved fire control
