Release Information

You can find the current and past release information for our platform below. There is more to come! Enjoy the platform. 

December 2019

The WinJi development team has been working hard before the holiday season. With the new features, you can find answers to the following questions:

  1. How can I set up an alarm to let me know about KPI anomalies in my portfolio?

  2. Can I verify whether the wind speed measurements in a park are correct?

  3. What turbines are performing best/worst and with what efficiency distribution?

Please find the answers below: 

1. KPI Alarm Email
Not known to all our customers: An automated email service tracking the most important KPIs is available.

Contact us to set it up for you.

 

 

         

2. Wind Speed Validation

You can find the new feature to validate wind speed measurements under the "Condition Monitoring" menu after choosing a park.

It is a very important feature since a lot of analyses are based on wind speed.

Technical details

The anemometer measurement is evaluated at 4 different fixed operating positions at: 

  • given blade angle in wind region 2,  and

  • rotorspeed

If at least 3 operating positions measure too low or too high wind speeds, we recommend to check the sensor regarding calibration issues.

3. Turbine Efficiency Distribution and Outliers

Use the new graphical view by choosing a park and navigating to "overview"  under the "benchmark" menu. Toggle between table and graphical view with the arrow on the top right corner. 

The efficiency distribution per turbine is evaluated over the past months.

Analysis of Wind Turbine Efficiency

November 2019

Our goal last month was to enable you to answer the following questions using the TruePower platform.

 How can I …

  1. …find out more detailed information if I see a red traffic light in either the portfolio or park overview?

  2. …get downtime analysis at a deeper level than the existing categories?

  3. …compare the power curve of a specific turbine to a benchmark power curve of the same turbine type?

  4. …see the optimisation potential of our parks?

  5. …see the energetic availability per park?

New features and optimisations allow you to answer these questions:

  1. Click on the arrow above the traffic lights to jump to the corresponding graphs.

  2. In the downtime analysis, switch between a category, subcategory and errorcode view by clicking on the arrow in the top right corner.

  3. Check out the new view comparing the power curves of: a) the turbines of your park, b) the OEM and c) other turbines of the same type in the WinJi platform

  4. Columns showing the optimisation potential (in MWh and %) are added to the park as well as portfolio benchmark views. Both the optimisation potential and the difference between expected and real energy production are now shown in the header.

  5. On the Portfolio level, you can now find an overview graph on the energetic availability of your parks.

October 2019

Our goal last month was to enable you to answer the following questions using the TruePower platform.

  1. How can I identify the most important issues at a glance in our portfolio?

  2. How can I optimise my existing turbines to improve my revenues?

  3. How many losses do I have per turbine and park, why and when?

  4. What are the main anomalies in the machine behaviour for predictive maintenance and to avoid future problems?

  5. Which OEM provided you with the best turbines? In which country are they working best?

New features allow you to answer these questions:

  1. Survey the new Traffic Light view on the portfolio level and use the colour code to get insight on Operation Status at a glance, Energy Efficiency (over 7 and 30 days) and Energetic Availability of your portfolio. 

  2. Get the AI-based Yaw Optimisation module from WinJi. It provides you with an optimal setpoint for each individual turbine across 12 wind sectors.

  3. Use the “Loss Drivers” menu to quantify your losses based on WinJi's downtime categories presented in gross and net view. The remaining control logic losses provide insights on the optimisation potential through yaw and pitch control. Use the “Condition Monitoring” menu to check machine parameters over time and compare your turbines at the same working conditions. 

  4. Use our optimised trend view to see power or rotor speed at a fixed air density and wind speed over time in order to correlate technical parameters to drops in performance. 

  5. Use the OEM and Country benchmark to find the over- or underperforming turbines and parks in your portfolio with ease.
