Evaluating the accuracy of condition-monitoring systems

摘要

There are many different condition monitoring systems available that provide information on the current health of your wind turbine. Unfortunately there is no yardstick to evaluate and compare the performance of these different systems. Germanischer Lloyd maintains a certification process for vibration-based and oil debris condition-monitoring systems (CMS) based on a specification, but the process does not directly address performance. While there are several facets to CMS performance, such as timeliness of detection and what action to take based on the information provided, system accuracy is the least understood.
