TCM® Site Server

The unique software platform for managing TCM® installations

The TCM® Site Server is the backbone of the TCM® solution.  It collects and consolidates 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.

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.

The alarm filter will allow you to sort through the alarms, so that you can take action on the most important fault.TCM® Site Server

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.

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.

With TCM® Site Server Masks, you set the boundaries!

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:

Component Requirement
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
Network 100 Mbit
Storage RAID storage technology
Storage space Typically 5 GiB per turbine (depending on configuration)


TCM® Monitoring System

The Site Server has an Availability Map found under the ‘‘Administration’’ page, which shows weekly availability or ‘‘online connectivity’’ 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)
