Towards a cooperative life cycle documentation for distributed renewable energy power plants

Requirements analysis of IT-support for daily operation of power plants for renewable energy (viz. solar, wind, and biochemical) shows a need for new, primarily cooperation-supportive functions, especially in the area of maintenance and repair. One central consideration is the need for a so-called digital logbook, a complete and consistent central pool of all data and documents generated in the course of a power plant's life cycle. In this article, we describe an excerpt of a reference data model for such a logbook, showing how model concepts fit multi-party cooperative error detection and repair processes. Thereafter, we present an IT-architecture for logbooks as federated data service. In our work, we discuss and incorporate present results in international ISO and IEC standardization relevant to renewable energy power plants.
