Re: 1.5 MW WTG SPC reports

Hollis:

I am forwarding this to our Controls Group people who are working on a manual
with full description of all sensors, locations, identification, names, etc.
I am asking them to complete your list and get back with you. I should know
next week how long this will require.

Regards

KLC

Subject: 1.5 MW WTG SPC reports

Tom/Kevin,

In the development of the 1.5 MW WTG Statistical Process Control (SPC)
reporting tool we have some additional questions regarding the data which
comes to us from VisuPro. In the attached spreadsheet you will find a
listing of most of the channels which VisuPro uses to record data. With some
exceptions, each channel should correspond to a transducer on the turbine.
The channel name and number can be found in the left columns as they are
presented in VisuPro. The "Alias" column is my attempt to better understand
the channel and put a more meaningful label on the channel for presentation
to the field personnel. Wherever there is a blank it means that I do not
have a good explanation of the channel and need more information.

You can ignore the grey shading. It is just an indicator as to whether the
particular channel is currently included in the existing version of our SPC
analytic. The more interesting column is the "Include" column which is our
future plan regarding inclusion of the particular channel in the next
revision of the analytic.

Please do provide comments regarding simplified label names. Also please
note that I need further clarification on cells with comments inserted (look
for the red traingle in the top right corner of 3 of the cells).

The other thing I would really like to have is a picture, or drawing, of the
exact location of each of the transducers we are planning on including. This
would give myself and the field personnel great insight as to what the
measurements really represent.

Thanks,
Hollis
