Small Wind Training and Testing Facility

Welcome to the Small Wind Training and Testing Facility data page! This page is still under development but when finished you will be able to view and download data collected and stored from all the instruments and sensors currently installed at our facility on campus, including:

Weatherbug Data

You can retrieve weather data from our Weatherbug station in several different ways:

  • Real-time weather data measurements from the Weatherbug station at JMU. This gives you an indication of current weather conditions
  • Hourly-averaged daily data for the past 120 days. When represented in this format you can observe how weather conditions have changed during the day. Data more than 120 days old are discarded and are not accessible.
  • Daily-averaged monthly data has been recorded from the Weatherbug data since June 27, 2013. On this page, you can observe the average weather conditions for every day and how daily weather conditions at this station have varied over that month
  • Our Weatherbug camera provides real-time video from our camera at the facility of the parking lot just outside the SWTTF

You can also download the WeatherBug App to access this data from JMU or any other Weatherbug station to see their current wind speeds and other weather conditions.

Outback Power Status

The Outback Power Data allows you to view in real-time the solar energy output and the total energy going into and coming out of the facility’s inverters. You can view information about the battery bank and the facility using the inverter data tab, including:

  • Outdoor and Indoor Temperatures
  • Humidity, Pressure and Rain
  • Wind and Average Wind
  • Gust and Interval Gust
  • Solar Output

MetOne Data

The MetOne data tab contains all the data recorded from the anemometers and wind vanes attached on the turbine tower. Wind speed, wind gust, and wind direction measurements are recorded every half hour at the 10-meter, 20-meter and 30-meter levels. These data can be used to analyze the wind resource at the facility, including common analyses like monthly averages, diurnal cycles and wind roses.

Westridge Power Meter

The Honeywell data tab gives you an interactive display of energy data acquired from the Honeywell WEB-201. This data gives you information over the past week about:

  • How much power is being drawn from the JMU electricity grid?
  • How much power is being sent back to JMU from the facility?
  • How much electricity the SWTTF’s turbine/s and solar panel/s have generated?
  • How much of this energy has been sent to the JMU electric grid?
  • How much energy is required from JMU if not enough electricity is being generated to meet the facility’s load?
