NEPTUN Power Plant Management

Your Target

For single power plants as well as for power plant cascades, power production has to be maximised whereas the costs have to be reduced to a minimum.

Modern power plant management systems have to fulfil these tasks in a very efficient way. Beside the plant's operational requirements (e.g. maintenance cycle) the system has to take into account a number of external regulations (water management, contracts, environmental regulations).

Production planning requires different modules for forecasting and optimisation. 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 - maximising of energy production - the system has to support the operators in all different operating conditions (e.g. normal operation, flood and disturbances). At the same time the system has to contribute to the reduction of operation and maintenance costs.

On the basis of the existing infrastructure, an easy integration into the power plant's environment must be possible.
