Network Hardware

  • Connectivity between the CMS, located in the nacelle, and the tower base (TON) which will then connect to other WTs and to the Farm Area Network (FAN).

  • Selected hardware will provide support for the following network architecture:

    • Located in nacelle, tower base & Remote Operations Center.​

    • The WT network interconnects using fiber optic cable.

    • A ring topology is implemented to provide network redundancy.

    • Where required, redundancy protocols are implemented.

Wind-Turbine Condition Monitoring System (CMS)

  • The Yanos Technologies Condition Monitoring System (CMS) continuously measures, and processes signals produced by transducers mounted on specific components in the WT.

  • The data is transmitted to a Remote Operations Center (ROC) using fiber optic technology.

  • Each dedicated CMS contains resident software to provide signal processing of measured analog and digital parameters for a single WT.

  • Each CMS transmits the processed data in calibrated engineering units to the host computer system.

  • Each CMS is configured to continuously monitor parameters and transmit alarm conditions, in real time, as defined by the WT OEM and the end-user.

Vibration Monitoring

  • Vibration parameters are derived from amplified piezoelectric accelerometers.

  • Tower structure sway will be monitored using a 2-axis accelerometer in place of two individual transducers.

    • Main bearing​ - turbine main bearing.

    • Low speed stage - planetary gear/bearing.

    • Intermediate stage - planetary gear/bearing.

    • High speed stage - high speed gear/bearing.

    • Generator inboard - inboard bearing.

    • Nacelle transverse - tower sway perpendicular to the turbine centerline.

    • Tower axial - tower sway parallel to the turbine centerline.
