Brochure SitrackVibes - Wind

2. The MPW1000 system is a powerful tool
devoted to the wind power generation industry
that allows controlling the operating status of
tower, blades, generator, gear boxes, and
auxiliary parts in real time. The main purpose is
to improve the efficiency of production
processes based on synchronous and
asynchronous machines.
The MPW1000 system performs an incipient
and automatic analysis of signs operating in a
threshold prior to their occurrence. The system
works automatically and on an on-line basis on
machines under operation allowing failures to
be detected earlier and thereby reducing
operating and maintenance costs significantly.
The MPW1000 system provides unique
protection characteristics to monitor the
mechanical, wind, and electric performance of
the machine independently during startup,
loading, and rated power stages. This system
shutdowns the machine if an anomaly that
could damage its structural integrity is detected.
It acts earlier than other protection systems
available on the market.
The benefits resulting from using this system are:
• Early detection of incipient failures and anticipation of their consequences
• Optimization and effectiveness of maintenance activities using the predictive failure
system
• Optimization of the productive process
• Reduction of carrying costs and of spare part costs and reduction or removal of
fines imposed by control entities due to the suspension of machine operation.
• Reduction of unplanned stops and idle times
• Significant reduction of catastrophic failures

3. Basic System Diagnosis

etc.)
Synchronous Machines Diagnosis

• Synchronous generator status
• Inverter status
Asynchronous Machines Diagnosis
• Gear box status
• Generator status (bearing, poles,
etc.)
Protection and Optional Features
• Mechanical protection (vibrations,
non-allowed speeds)
• Electrical protection (load rejection)
• Starting diagnosis
• Seismic response
• Detector of crack progress on blades
• Detector of ice accumulation
• Virtual machine diagnosis

4. Diagram of the System
Instrumentation
The MPW1000 system uses signals from sensors located within the machine and process
signals. The system supports sensors existing at the power station and additional sensors
are installed as required. Signals from various sensors are used, including:
• Accelerometers
• Proximity sensors
• Pressure sensors
• Temperature sensors
• Humidity sensors
• Process variables

5. Protection
Sitrack Vibes offers a windmill specific
protection system that is capable of
detecting the abnormal behavior of
machines during startup, speed increase
to rated speed, synchronization with the
electric network, loading, and rated
power stages.
This is a unique system that protects the
machine during startup phases detecting
vibration levels caused by wind,
mechanical, and electromagnetic forces.
If a hazardous abnormal behavior is detected during these stages, a stop unit alarm is
sent.
This protection system includes self-calibration features so it can be adapted to every type
of machines.
Local Monitor
Monitoring, analysis, and diagnosis functions are carried out by a local monitor installed at
the power station. This monitor receives field signals and performs data conditioning,
filtering, and acquisition tasks.
Information is processed using an
industrial computer placed within
the monitor. Algorithms and
analysis models for machines are
the sole property and design of
Sitrack Vibes.
The local monitor generates on-line information on the status of the machine, as well as
alarm and temporary reports.
This information is sent to the local control room of the power station and to Sitrack Vibes.

6. Control Room and Local Analysis
The local control room shows the diagnosis on the machine status in real time. Alarms and
reports that contain all the signals and parameters measured are also provided.
Additionally, temporary signals, spectra, and historical trends can be analyzed.
Software suites including specific analyses are offered. They allow conducting the
following activities:
• Visual supervision and analysis of the machine vibratory behavior in real time
• Comparative supervision and analysis of the dynamic behavior of the rotating set
during startup
• Real-time analysis of the generator air gap
• Monitoring of generation power in each unit
• Monitoring of weather variables
• Monitoring of blows and cracks

7. Sitrack Vibes Facilities
Sitrack Vibes servers are located in
the city of Mendoza. They are
equipped with the elements and
tools required to post-process
signals received and to store reports
and inform alarms.
On-line information on machinery
status as well as report and
historical alarm information can be
accessed through the Web.
Sitrack Vibes facilities also
accommodate a 24/7 monitoring
room. When an alarm is generated,
it is received and processed by
Sitrack Vibes operators, who inform
it to the contact persons previously
defined by the client by telephone,
fax, or e-mail.
Sitrack Vibes has a mechanical analysis service led by expert engineers. This service
ensures that machines are monitored every day and that analyses and trends on incipient
failure signs are prepared.
This customized service is provided optionally and operates in parallel with the on-line and
automatic analysis and diagnosis features of MPW1000.
