the science
At the core of Melogale™ is a sophisticated downtime analysis tool, aiming to give a clear picture of all turbine activity from commissioning to the present day. This includes:
Software pre-processing
- Identification of turbine failure timings
- Meteorological analysis
- Grid availability
- Application of pattern-matching algorithms to SCADA data
Operator post-processing
- Alterations to meta-data according to on-site reporting
- Categorisation of failures according to subsystem and contractual definitions
- Derivation of new algorithms to improve pattern-matching
- Verification and cross-checking of available data
Finally, meteorological analysis is applied to give an accurate, benchmarked picture of gains and losses so that every last kilowatt-hour of the budget can be traced.
Product features include:
- Post-construction Yield Analysis, by re-evaluating projected yield figures for sites with reduced uncertainty, which can permit a release of equity as well as refining annual budgets to reflect the known performance of a site
- Downtime Analysis providing in-depth information of events leading to the loss of production, correlated with meteorological data, allowing prioritisation of maintenance operations, early identification of serious faults and improved decision making
- Budget Deviation Analysis evaluating site operations against the projected budgets for the site along with associated uncertainty reported for turbine downtime, turbine performance and wind distribution
- Warranty Calculations enabling site owners to derive complete and accurate warranty claims
Product accreditations include:
- Actively supporting an installed capacity of almost 200MW at a number of sites across the UK
- Downtime Analysis for Improved Decision-Making presented at CanWEA 2006 and EWEC 2007
