Example of event frames in a wind power generation company
Take the example of a wind power generation company that has different types of windmills across different locations and uses PI AF to organize their data. Their asset framework structure is based off a base element template of type "windmill", and has various child templates based off OEM, model, and megawatt ratings. The wind operator may want to win favorable warranty contracts by showing that the blades are operating safely. Or, the operator may need to monitor parameters such as oil bearing pressure, maximum voltage, power-factor, or performance of electronic and mechanical brakes in the minutes before process trips occur. In all these cases, you can associate event frames with the specific event frame attributes.
The sample windmill element may include these asset attributes and associated event frame attributes:
|
Asset attribute |
Event frame attribute |
|---|---|
|
RPM |
Instantaneous and maximum speeds |
|
Voltage |
Maximum voltage |
|
Power |
Power at current time |
|
Yaw |
Yaw at current time |
|
Pitch |
Pitch at current time |
|
Oil bearing pressure |
Maximum oil bearing pressure |
Since all types of turbines share many identical attributes, you can create just one event frame template and use it to monitor similar events across the different assets. For example, you may be interested in the RPM attribute to capture a speed-based event. Using the special notation .\Elements[.]|RPM in the template enables you to use the template on any windmill, and access the attribute of the particular referenced element.
Example of event frames using Asset Analytics
