TCM® Site Server
The TCM® Site Server is the software platform for managing TCM® installations. The TCM® Site Server is the backbone of the TCM® solution—collecting and consolidating data from the M-Systems (TCM® hardware front-ends) mounted in the wind turbine nacelles. The Site Server software requires an acquisition of the M-System.
The alarm filter will allow you to sort through the alarms, so that you can take action on the most important fault.
The TCM® Site Server can be situated in the location of your choice e.g. in the control room of a wind farm substation or at your corporate headquarters. The only requirement is that you have an Internet connection. When you are ready to take your TCM® solution to the next level, consider the TCM® Enterprise Server for instantaneous monitoring of multiple TCM® Site Servers.
How does the TCM® Site Server work?
The TCM® Site Server offers the complete monitoring solution for your site, offering an interface for investigation (data mining) and eliciting alarms for abnormal conditions.
The TCM® solution from Gram & Juhl involves a server for reliable data processing and storage. The TCM® Site Server is the backbone of the TCM® intelligent monitoring system – collecting, managing and consolidating data from many M-System front-ends. The M-System firmware analyzes vibration signals from the drivetrain, structural vibration signals from the M-sensors and other processing parameters such as wind speed, temperature, ice detection and oil quality.
The M-System directs the results of these analyses to the TCM® Site Server. The TCM® Site Server then analyzes these measurements via specially calibrated masks. These masks monitor the noise levels inside the drivetrain and when digressed, send alarms to the CMS operator keeping you informed of up-to-date conditions within the turbine.
Monitoring with masks
A “mask” is Gram & Juhl’s term for a limiting line, the transgression of which can activate certain alarms, i.e. blue, yellow, and red. Alarms are collected by TCM® Site Servers and Enterprise Servers and subsequently presented to CMS operators.
Masks can be applied to any configurable measurement, and are effective thresholds for signaling an impending failure.
How are these limits defined?
Initial default values for yellow and red masks are generated by the system using defined parameters and measurement statistics recorded during a period of time when the turbine is still known to be operating soundly. The initial default settings generated by the TCM® system are based upon our long-standing experience in signal processing and the research of many experts in the field including Robert Bond Randall. Not only have these thresholds been defined conceptually, they have been put to the test in the turbines themselves. We are well-versed in the complications that arise when certain signal amplitudes are overstepped.
The parameters defining the mask lines are user selectable;
users may change the default values generated by the TCM® system
once they have built-up their experience with alarm handling.
TCM® Site Server Hardware
The TCM® Site Server application is meant to run over long time spans (years). Accordingly, it demands professionally supported hardware and is either physical or virtualized and is not included in the Site Server package.
The TCM® Site Server system requirements are:
|Operating System||Windows Server 2012 R2|
|Processor||1.4 GHz or more|
|Memory||8 Gib RAM as minimum requirement|
|OS Disk Space||32 GiB or more|
|Storage||RAID storage technology|
|Storage space||Typically 5 GiB per turbine (depending on configuration)|
Monitor TCM® System Uptime
The Site Server has an Availability Map found under the ‘‘Administration’’ pane, which shows weekly availability or ‘‘online connectivity’’ for a selected component (ie. M-System or sensor). The Availability Map shows weekly availability for a selected component (ie. M-System or Sensor).
Availabilities are displayed on a color scale ranging from red to green.
M-System availability is measured in “nines” and ranges from 0 (bad) to4 nines (good).
Sensor availabilities range from 0 (bad) to 100 (good)
