Estimating energy production

by Alan Axworthy, Director, Application Engineering Estimating the amount of energy a wind turbine will generate in a year is a key factor in determining the viability of any wind development project. To do that responsibly, it is important to understand wind characteristics, especially its variable nature. Equally important, however, is an understanding of site and operational issues that affect the ultimate, bottom-line net usable energy production from a wind turbine installation. Wind Characteristics When it comes to generating electricity, the single most important characteristic […]

Foundation Overview for the NPS 100 and NPS 60

by Alan Axworthy, Director, Application Engineering The design of the foundation for a Northern Power® 100 wind turbine (NPS™ 100) at a specific site is the responsibility of the project developer. Because soil conditions can vary dramatically from installation to installation, the project developer must conduct a geotechnical investigation at each site to determine what conditions exist. Those conditions must be taken into account by a competent structural engineer, licensed to practice in the jurisdiction of the site, in his design. The loads that are […]

Only NPS offers Britain a 10-Year Performance Guarantee

By Iain Hardie, Sr Sales Manager UK & Ireland Earlier this week, Northern Power Systems announced its new wind turbines will be backed by its 10-Year Performance Guarantee Programme (PGP) in the United Kingdom, the only 10-year guarantee programme for small wind turbines available in Britain. Reinout Oussoren, our VP of Global Sales, commented about the new programme, “This type of performance guarantee programme is normally only seen with utility scale projects and is the first of its kind offered for wind turbines up to 100kW […]

Reactive Power Compensation: Using a Northern Power® NPS 100™ or NPS 60™ wind turbine to manage power factor

by Alan Axworthy, Director, Application Engineering Electrical systems using alternating current are subject to situations where voltage and current get out of step with each other… they get “out of phase.” When voltage and current are out of phase, the power produced – the product of voltage times current – is affected. Apparent power, what is metered and what we typically pay for, is composed of real power, that provides useful work, and reactive power, that only exists to balance out the misalignment between voltage […]
