Presentation Description: There are two main differences between Condition Monitoring Systems (CMS) and Advanced Analytics (AA). The first difference is hardware requirements: CMS requires additional sensors to be installed in the turbines, while AA is based on existing data sources—primarily SCADA data.
The second main difference is possible outputs. CMS can more accurately detect and diagnose issues related to excessive vibrations of main bearings and gearbox. However, CMS are more limited in scope, and do not generally address performance monitoring/optimization, turbine control validation and other elements addressed by AA.
Considered separately, the relative cost benefits of the two techniques depends on the targeted outcomes, and on the costs of sensors and the corresponding calculations. Since results from the two methods are complementary, there can be substantial added value from a combined approach. AA can extend existing CMS using analytics of turbine performance, control, and availability which are not considered by CMS.
For example, improved preventative maintenance with CMS can reduce maintenance costs related to main bearing and gearboxes. AA can help reduce maintenance costs on these components plus help with maintenance costs on other turbine components and on the Balance of Plant. The most important argument for a combined approach is that it has been demonstrated that AA can also increase revenue not only through reduced maintenance costs but through improved performance.
understand the two main differences between Condition Monitoring Systems (CMS) and Advanced Analytics (AA).
determine the relative cost benefits of the two techniques--both when used individually and when combined--based on targeted outcomes and on the costs of sensors and the corresponding calculations.
