Neptun - power plant management

Power production must be maximized, while the costs should be reduced, both for single power plants as well as for power plant cascades.

Modern power plant management systems perform these tasks very efficiently. Beside the plant's operational requirements (e.g. maintenance cycle), the system has to take account of a number of external regulations, such as water management, contracts, and environmental regulations.

Due to the growing number of solar and wind power plants, optimum delivery of control energy (secondary control, tertiary control) is also gaining importance.

Production planning requires different modules for forecasting and optimization. Information has to be provided to other applications (e.g. commercial and administrative software tools) via standard interfaces.

All these different requirements require a modular overall concept.

Besides its main task - maximization of energy production - the system has to support the operators in various other operating conditions (e.g. normal operation, flood and disturbances). At the same time, the system has to contribute towards reducing operation and maintenance costs.

It must be possible to integrate the system easily into the power plant’s environment on the basis of the existing infrastructure.
