Wind Turbine

WIND ENERGY A RENEWABLE AND CLEAN ENERGY SOURCES.

Smart Wind Turbine Monitoring is easily installed on new or existing units.

Pure I/O: Wind Turbine Online Monitoring System.

Our monitoring device uses two different type of Communication, because of the physical layout of the Wind Turbines a mesh network is a powerful way to route data. This methodology extends range capabilities by allowing data to hop from node to node, using IEEE 802.15.4 operates in bands 900 MHz: Frequency-Hopping Spread Spectrum (FHSS), with a secure 128-bit AES encryption. The secure route data from the mash network communicates to cellular CAT-M1 technology - providing a totally separate from Legacy Systems such as SCADA, DCS, and PLC. Not impact your security policies. The Pure I/O Smart Wind Turbine Monitoring System hardware is designed not only to gather data, but combining with OPEX 3000 application can make decisions that will inform the end-user in presenting equipment condition and its critical components or systems. The OPEX 3000 capability allows the end user to understand the lifecycle (frequency) of key components (parts), to maintain the highest level of the equipment and its performance. By presenting the data to the end-user he/ she can understand critical information about equipment condition and health, such as: Gearbox, Generator, Hydraulic System, Lube Oil System, etc. The lists below identify monitoring points that have a major influence on the performance of the Wind Turbine and its condition.

Portable Handheld Capabilities for wind turbine inspection

OPEX 3000 system has embedded a handheld data collection application that allows the end user to develop its own routine for Wind Turbine inspection. The application allows multiple types of handheld data collectors and does not force the user into dependency on one type of manufacturer. This innovative application which automates periodic inspections and diagnostic activities such as PdM type rounds: Tower, Generator, GearBox, MCC, and Overall equipment Inspection for Thermograph, Vibration, acoustics, oil sampling, off-Line Testing etc. Using these low-cost electronic data loggers with bar coding capability allow field personnel to collect, store, and analyze the data that has been routinely collected. Once the data is collected in the field, it is uploaded to the central database for processing, analysis, and data warehousing. Using a standard Internet browser, site personnel can then gain access to equipment status, condition monitoring data, trends, alarms, exceptions, and reports for evaluating equipment condition. The benefits include: an increase in productivity, better utilization of data for decision making, easy access to information and trends, and automatic alarming (via email) for out-of-spec conditions. The OPEX 3000 system is designed to facilitate the integration of information collected regarding equipment health, and provides a cost-effective process for disseminating and sharing information within the organization to make operating and maintenance decisions.

Basic Functions

Main Drive Mechanism: Temperature

  • The ability to have previous value displayed.
  • Alerts when a value exceeds limits.
  • Helps the inspector to determine if data is within a normal range.
  • Data Validation for each monitoring point.
  • Allows inspectors to attach comments and/or create exceptions.
  • Field request generated Work Order.
  • Helps the inspector to determine if data is within a normal range.
  • Comments can be predetermined based on equipment category.
      1. By handheld bar code flip cards.
      2. By drop down list.

      On-Line Monitoring Capabilities

      Avoid Costly Gearbox Failures | Extend Generator Life | Reduce Maintenance Cost | Avoid Unscheduled Downtime .

      Radio Mesh network nodes combined with cellular communications to the InterNet.

      Mesh networks are decentralized in nature; each node is capable of self-discovery on the network. Also, as nodes leave the network, the mesh topology allows the nodes to reconfigure routing paths based on the new network structure. The characteristics of mesh topology and ad-hoc routing provide greater stability in changing conditions or failure at single nodes.
