ADVANCES IN REMOTE SENSING & MONITORING


A key factor in allowing wind turbine owner operators to make decisions on the running of turbines is the data availability real time. The ability to make crucial decisions on maintenance should be based on accurate sensor data measurements.


Sensor data as connected to turbine gearboxes and generators, bearing systems and shafts allows the measurement system to send data to remote location servers which in turn perform runtime algorithmic calculations and make automated system level decisions and inform staff on these decisions.


By example gearbox deterioration or ‘wear’ through mechanical issues and oil characteristic changes are measured and predicted real time. The measurement of ferrous and non- ferrous metal particulate gives the system a clear indication of a failure progression.


Wear debris measurement sensors get typically installed between the off line pump and filter on the gearbox and in effect this makes the filtration system metal content quantifiably measured and when the particles within the oil lubrication system are quantified and sized this information is collated or ‘fused’ with other sensor parameters and a clear indication emerges on the overall gearbox condition. Other sensor data is collected and analysed at the same point in time allowing improved machine health decisions to be made.


TECHNOLOGY SELECTION


The M-HAS system allows the data from multiple sensors to be collected, presented and processed showing the operator immediate issues or concerns on individual turbine systems.


The adjacent list shows the type of multi sensor data that are frequently used to determine an improved picture on the health of the machine…


• Oil condition and indications on changes in oil due to moisture, changes in viscosity and cleanliness


• Gear and shaft vibration levels at critical points such as the bearings and the gearbox gears


• Mechanical wear through metallic debris in oil for bearings and gears and showing the increase in counts with a progression of machine fatigue wear


• Generator measurements such as temperature and vibration


SPECIFICATION


Instrumentation is selected fit for purpose for measurement and collection of data which when Turner staff analysed in time provide a solution to identifying the customer’s problematic plant issues and servicing needs. These instruments also are typically performance proven sensing technologies and were introduced into the system for ease of installation and integration.
