The Aspiravi Group develops, invests, realizes and operates wind projects in Belgium, the North Sea and abroad to create a sustainable future for the next generations. Aspiravi owns and operates a diverse and growing portfolio of wind farms. At the end of 2014 the portfolio consists of 480 MW of Enercon, Senvion, Siemens and Vestas turbines.
Ventolines, Netherlands-based service provider in the wind energy, has chosen the Breeze system for wind farm management and analysis. A portfolio of turbines ranging in size, age and brand will be installed in the Breeze system.
This final e-book of the 3-part series focuses on measuring change in power performance. There is a brief review of the Power Curve, Annual Energy Production and common methods of measuring the absolute level of power performance. The alternatives for measuring change in power performance for a specific site are narrowed down. An in-depth case study is performed, presenting the methodology and results of the Side-by-Side Testing method. Using only SCADA data for the analysis, the effect of a blade add-on upgrade is evaluated. The analysis is based on a relative power relation between a test and reference wind turbine.
A notification is an e-mail sent from Breeze to notify a user of specific events that occur in the wind farm. Notifications are configured using notification schemes. A notification scheme can be configured to send notifications whenever a turbine status is registered. The notifications are very flexible and can be configured in many different ways.
The first Breeze Customer Day has just come to an end and we are more than happy with the outcome. With the fast pace of innovation, we want to make sure users of Breeze are getting the most out of the service and that is what the Breeze Customer Day is for. This year's event featured an introduction and training on the main features of Breeze, from power curves to scheduled downtime to sharing data via API and reports as well as discussions of best practices, new ideas and “the big picture” as a group. We are looking forward to see you soon again! Click the article for more photos from the event.
Sometimes you can see that turbines have information code 9997 – Data communication unavailable: Turbine – Breeze. This is a general code that means that Breeze doesn’t receive data, specifically the signals “wind speed” and “power”. In this part of Breeze Academy we describe what code 9997 means and how to handle it in Breeze.
