Operation Management
Our experience:
We started the operation management of hydro-electric plants in 1985 and the operation management of wind parks in 1998.
Christoph Eckert, general manager of RENERTEC GmbH and head of RENERTEC`s management service for energy-producing plants is well experienced in the management of hydro-electric plants and wind parks. Practical and further studies have enlargened his mechanical qualification, resulting in comprehension know-how of any energy-producing plant and equipment especially for wind and hydro power plants. Considerable experience has been acquired in the operation of equipment supplied by manufacturers such as Enercon, GE Wind, REpower and Fuhrlaender and Ossberger. Constant contact is maintained with the service departments of these suppliers regarding monitoring, performance improvement and maintaining the latest technical standards.
The thesis for his graduation as engineer sponsored by one of Europe's leading wind turbine park planner and operator, analyses the operating efficiency and availability of a 10 units turbine wind park (stall turbines, each 1 MW rated, pole switched)
Gerhard Eckert, RENERTEC`s managing director is well experienced in project management and supply of nuclear power stations in more than 30 years, he also developed successful concepts of preventive maintenance thereof. His knowledge and experience of many years of work in the energy generation sector is at the disposal of technical management at all times.
Our philosophy:
- intensive, committed service and online-monitoring of wind turbines by qualified staff
- continous effort to reduce defect-related downtime
- staff schooling in plant engineering techniques and their further development.
Our service:
- analysis of fault data and their distribution to identify trends with monthly reports to owners illustrating wind park operating characteristics and revealing system faults
- 24 h remote monitoring of the technical state of generating plants
- technical plant inspection/expert knowledge
- insurance negotiation
- optimization of plant availability and efficiency, involving regular presentation of performance graphs/power curves and fault occurrence data (particularly important during the period of warranty)
- regular contact and meetings with service departments to co-ordinate and monitor operation and maintenance with the aim of optimising availability and efficiency. Exchange of information deriving from fault data analysis and performance graphs
- creation of wind park data archives
- exchange of information on systems engineering and weak points of it
- organisation, co-ordination and service of regular rotor, transformer and general technical maintenance
- Service repairs of plants in co-operation with their owners.
