Temperature compensation in the NRG BP60 barometric pressure sensor

Published

on

The NRG BP60 is a drop-in replacement for the BP20 Barometric Pressure Sensor. There are several improvements introduced in the BP60, but perhaps the most important is the introduction of native temperature-compensation.

The BP60 continuously measures the temperature of the air volume that is being sampled inside its housing by its barometric pressure sensing element and factors this internal temperature into the sensor’s barometric pressure output. The temperature sensing element has a very low thermal mass, which allows it to react to changes in internal temperature almost immediately.

The performance improvement can be dramatic in situations with rapid temperature swings, including diurnal cycles such as the one shown in the example below from NRG’s internal BP60 field test. At the beginning and end of the time series, the BP20 (dashed yellow) agrees with the cohort of three BP60s fairly closely (approx. ± 1 hPa). However, during the daytime, there is a pronounced divergence, with the BP20 reading approximately 5 hPa higher than the BP60s as the temperature increases about 20°C over a five-hour period, from just over 2° to 22°C (solid teal). The BP60 cohort continues to read within ± 0.5 hPa throughout the same period.

The BP60’s onboard temperature compensation improves the sensor’s overall measurement accuracy relative to the legacy BP20, enabling improved estimates of future air density and annual energy production, and more reliable forecasts on operational solar and wind farms as well as in general meteorology use cases.

Second Wind Turbine Technical Training by TWRE and Nordex Acciona has been achieved in İzmir between 20-22 October.

TWRE, Turkish Women in Renewables and Energy, was founded in 2018, in order to create a network for women who take part in energy industry development and transition, as a platform for “Gender Equality” in the energy sector in Turkey. 

TWRE, which has more than 1300 members and thousands of followers today, held the second Wind Turbine Technical Training in Izmir on 20-21-22 October 2020 together with one of the world’s biggest wind turbine manufacturers Nordex Acciona. In the program, which was initiated to train white and blue-collar women for the wind energy sector, 10 young female candidate who are graduates of vocational high schools, senior students and recent graduates of electrical, mechanical, construction, meteorology and energy system engineering of universities from İstanbul, İzmir and Ankara, had the chance to have a detailed theoretical and practical training for 3 days this year. 

On the first day of the program, wind turbine types, turbine mechanical and electrical system components, SCADA system, Delta4000 turbines were explained in detail. 

On the second day of the program, a visit to Nordex İzmir Office and Training Center provided a practical view of the theoretical training and system components. During the site visit held on the last day, PİTANE RES N117 Gama, YUNTADAĞI RES N90 Beta ve Gama, AKÇA RES Delta4K turbines were visited and operational observations were made. 

TWRE Founder President Ms. Sedef Budak’s comments on the program were: “We are very pleased that such a valuable training has become traditional, it was very important for us that young women take part in the transition of energy and guide their careers in the field of renewables. We thank a lot to Nordex Turkey for their support.”

Leosphere launches Windcube: Power to customers with data and analytics

Published

Windcube Insights is the first out-of-the-box software solution to leverage lidar and turbine data for cost-efficient power performance testing

Leosphere, a Vaisala company that specializes in developing, manufacturing, and servicing turnkey wind lidar (light detection and ranging) instruments for wind energy, aviation, meteorology, and air quality, today announced the launch of Windcube Insights at Wind Operations Europe 2020 in Munich. Windcube Insights is a proprietary data analytics software designed specifically for the Windcube Nacelle (previously called Wind Iris) nacelle-mounted lidar that simplifies the wind turbine power performance testing process.

“This new tool empowers operators with International Electrotechnical Commission (IEC)-compliant data to verify that turbines are performing as promised so they can maximize the energy output of their wind farm,” said Alexandre Sauvage, CEO of Leosphere. “The easy-to-use software allows operators to perform power performance testing and suggest operational optimization — quickly, accurately and efficiently.”

Windcube Insights enables true and fully transparent data analysis and reporting for Windcube Nacelle customers — all within a web-based user interface. The software is the first in the industry to enable the upload of both Windcube Nacelle lidar and supervisory control and data acquisition (SCADA) turbine performance data with a simplified data synchronization process.

The method of operation:

  • A variety of standardized lidar and turbine data filters are available and fully configurable by the user, simplifying preparation of the data sets.
  • The software leverages those data sets to calculate and display the power curve, and the complete set of IEC requirements can be applied with embedded guidelines that reference the proper IEC standard sections, making the service fully transparent and understandable.
  • The production data, along with standardized uncertainties, are calculated and can be exported in the form of a traditional report table.
Wind Turbine Power Curve Determination Value

The handling of IEC standard requirements for issuing a power performance test (PPT) is complex, requires deep expertise, and represents a potential source of error. However, such testing is necessary for regulatory compliance, warranty verification and turbine performance verification during both the development and operations phases. Determining the power curve of a wind turbine in accordance with recognized standards is valuable because the power curve is one of the most important characteristics of the economic value of a wind project.

The Windcube Nacelle lidar measures the wind conditions at hub height ahead of the turbine, enabling operators and wind turbine original equipment manufacturers (OEMs) to efficiently and accurately assess performance and optimize design and production efficiency. When fully integrated within the wind turbine, Windcube Nacelle enables load reduction, design costs reduction, and continuous production gains.

Seeing the global energy demand accelerate at its fastest pace in more than a decade, wind energy and other clean energies are increasingly becoming further engrained into the world’s equation for energy demand. Since 2010, the size of the global wind power market has increased by 35%, and the global market is expected to approach USD 125 billion by 2030.

“Without Windcube Insights, lidar users would have to build their own software programs to analyze the data being collected by the nacelle lidar and the wind turbine,” said Sauvage. “We’ve simplified the process of applying filters, calculating the uncertainties described in recognized IEC standards and displaying data, ultimately creating a simple way to support the utilization of nacelle-mounted lidar following IEC standards and industry best practices. Windcube Insights is just another example of Leosphere’s commitment to innovation and to making our customers’ lives better by introducing tools to help them maximize efficiency and productivity.”

Vaisala, a global leader in weather, environmental, and industrial measurements, acquired Leosphere in 2018.
