By precisely identifying the costs early in the process, you minimise the risk on your project significantly. Armed with our Electrical PreDesign report, customers are well placed for discussions with their own in-house power system experts, external power system consultants and transmission system operators. The report - reinforced with a presentation by our specialists and a detailed Q&A session – also describes optimal control strategies for use with Vestas’ Power Plant Controller. Making profitability predictable By identifying early grid code issues and simulating extreme operating conditions, Vestas’ Electrical PreDesign provides the surest way of building a grid compliant, productive and highly profitable wind power plant. By combining our experience of grid connections and turbine technology, along with our cutting-edge capabilities in turbine generator modelling, we can provide a highly accurate simulation of the wind power plant.

It contains comprehensive diagrams and simulated results. The report typically includes: Steady State Analysis An integral part of Electrical Predesign, is a Steady State Analysis, entailing load flow studies, short-circuit analysis in addition to power and energy loss calculations. Transient Analysis We conduct a comprehensive transient analysis consisting of capacitor switching studies, low voltage ride through as well as fault ride through analyses, and reactive power compensation final sizing. Low Voltage Ride Through and Fault Ride Through To maximise your turbines’ uptime and protect your equipment, it is useful to ensure that the wind power plant remains connected during low voltage phases or during faults at the point of common coupling. Voltage Control – a dynamic approach Many modern grid codes require dynamic response to voltage changes at the point of common coupling. This means that the reactive power response of the wind power plant must meet the appropriate ‘rise’ and ‘settle’ times for the grid. Frequency Control Conducting frequency control provides the ability to control the active power output as a function of frequency excursions for contributing to keeping the power system stable. Voltage Dip and Over Voltage Analysis Transformer energisation, reactor and bank switching studies. Protection studies As part of a the protection studies, we are performing complete relay setting and coordination of the wind power plant, arc flash analysis, power flow and short circuit currents as well as protection settings. Power Quality Analysis To ensure high-quality power, Electrical PreDesign contains harmonic penetration analysis, filter design and flicker calculation.2011-03-14T10:54:21+01:00http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/PowerPlantSolutions/ElectricalPreDesign/?Page=9http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/PowerPlantSolutions/ElectricalPreDesign/?Page=9Securing Optimal Electrical Balance of Plant Design, Scope of Supply and Dynamic Performance of The Wind Power Plant – Through Steady State Analysis and Transient Analysis.

Electrical PreDesign – keeping our customers ahead of the field Electrical PreDesign is not the only support package available to customers as Vestas offer a comprehensive set of support packages to support your wind power plant projects. Partnerships begin at the start of the project when, the benefits of competing locations are being assessed, and continue when planning the layout of the chosen site and the right mix of turbines to install. With the siting work in hand, our dedicated global team of power system engineers, control engineers, PhDs and other electrical experts model and simulate the plant design against the site specific grid codes and point-of-common coupling requirements for documented technical solutions. Our in-house supercomputer is among the most powerful in the world, offering invaluable data made up from fleet-wide monitoring, industry tools and unique Vestas tools. In addition, we have designed two specialist packages to ensure your business case is powered for success – SiteHunt® and SiteDesign®. In fact, Electrical PreDesign takes advantage of the extensive amounts of data gathered through these tools. SiteDesign® – data-based decision-making Once you have chosen a suitable location for your wind power plant, our SiteDesign® service allows you to reliably assess and configure the site to maximise the output and value – based on operational costs as well as actual energy production. It gives an accurate and reliable way to identify the most appropriate turbines, and the most suitable locations for individual turbines on the site. This makes SiteDesign® a crucial step in assessing the project’s potential – and reducing your overall cost of energy. The Power of Partnership At Vestas, we believe in the power of partnerships. The earlier we become involved in your wind power project, the sooner we can share our vast experience and powerful tools to your benefit. We can add value, save time and strengthen your business case at every step of the journey, from site selection and development to operations and maintenance. And Electrical PreDesign plays a crucial role in early discussions, helping to set your vision on the fast-track to profitability. SiteHunt® – finding a faster route to market Going even further in strengthening the business case certainty of our clients, we will do our utmost to help them bring their wind projects to market in the shortest possible time. A critical consideration is the ability to identify the most suitable location for your wind power plant, which is where SiteHunt® comes in. SiteHunt® is an advanced analytical tool that examines a broad spectrum of wind and weather data to evaluate potential sites and establish which of these provides optimum conditions for your project.2011-03-14T10:54:21+01:00http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/PowerPlantSolutions/ElectricalPreDesign/?Page=12http://nozebra.ipapercms.dk/Vestas/Communication/Productbrochure/PowerPlantSolutions/ElectricalPreDesign/?Page=12Vestas Wind Systems A/S Alsvej 21 . 8940 Randers SV .
