  1. General OverviewPower Plant Information System “KISSY“ Dipl.-Ing. Werner Hartwig 11th September 2008

  2. Basics and Purpose • Basics Definitions for Performance Indicators like forced outage rate • Purpose Providing a System enabling to a Tool for analysing the Performance for developing a better Operation Regime

  3. 11.09.2008 Performance & Monitoring Losses in Energy Conversion • avoidable losses, influenced by technical devices • - non avoidable losses, not influenced by technical devices • heat efficiency fed • with fuel in KJ/s • usable net electrical • output in KW • - heat efficiency in • KJ/s removed with • cooling water • - other losses in KJ/s

  27. Examples for KISSY Application • Redundancy Feedwater Pump • Damages in Gas /Steam Turbine • Transformer for strategic decisions on • Plant Concept • Maintenance • Spare Part Management

  28. EvaluationofnecessaryRedundancies major root causes are not the pump and motor auxiliary systems !

  29. Evaluation of Gas Turbine Failures caused by Design  out of Control …can be optimised by Operation Mode

  30. Evaluation of Steam Turbine Failures caused by Design  out of Control can only be controlled by maintenance

  31. Evaluation of Transformer Failures caused by Design  out of Control - Monitoring
