Wind Turbine Guide - Advanced Eco Solutions
Wind Turbine guideWind turbines are a fantastic option for you if you have the wind resource, here is a guide to makinggood decisions for you around wind. We will use products which we sell to show the differentoptions as we have a comprehensive range in wind.Key1.2.3.4.5.6.7.Reasons for installing windTypes of wind turbine technologyGuide to the components used in wind turbine installationsCouncils, Lines companies and Power companiesSite informationEconomicsSummary1. Reasons for installing windThere are three reasons people install wind turbines1. They want to reduce their existing power bill2. They want to use it as supplementary generation on their house or vessel3. They want to use it as a marketing tool for their business stating that they are committed togreen technologyOffsetting your existing load is done by installing a wind turbine which produces enough energy tosend any excess electricity back to the power grid. You use a grid tie inverter “converts wind energyto Mains power” to produce power credits on your energy meter. There are no batteries in gridconnect systems normally so the system will shut-down when the mains power is disconnectedSupplementary generation is a small low voltage generator which charges battery packs. Thesenormally supplement power generated from solar panels.Using wind as a marketing tool or a point of difference means there are other financial benefits tothe installation of a system. Commercially the site might not stack up as a generator on its own butthe turbine may add a point of difference for the business.
2. Types of wind turbine technologyVertical Axis wind turbineLeading edge windHorizontal wind turbinesVertical axis wind turbines rotate on thevertical up and down plane like an egg beater. Ourrange for this type of turbine is 600watt, 1KW and4KWOur Turbines rotate at a maximum of 120 revolutionsper minute. This type of design is extremely quiet asthey spin slow, have six tips where the noise isgenerated also reducing noise levelsVAWT because of the low noise levels are ideal for alltypes of wind generation.Wind DirectionLeading edge wind turbines have the bladesdownwind from the Pole. This makes the design andmaintenance simple and leads to some innovativedesigns. We supply units from 600watt to 2KWThey are great for rural systems and somecommercial sites. The 600watt units are ideal formarine useWind DirectionStandard Horizontal Axis Wind turbinesare the main wind turbines used historically.They come in sizes from 200watts-10KW and upto utility sizes 1-5Megawatts. They are efficientcollectors of wind energy and are ideal for ruraland marine use.We have turbines for our customers from200watts to the 10KW turbine pictured left

Mechanical components1. Polea. Mono poles are large poles without any support wiresb. Guyed poles have a thinner centre pole and a number of supporting wiresconnected for smaller turbines2. Foundations are designed to support the pole, guyed poles will have four or five supportingbases either drilled or poured foundations. Each foundation is engineered to meet local windloadings and must meet NZ standards. These generally need a building permit3. Pole lifts. Some poles can have mechanical lifting mechanisms as seen above4 Councils Lines companies Power companiesEvery council has different rules interpretations and guides within their district plan. Putting up awind turbine in some areas may need resource consent if your pole is over 7 metres, some areasthat’s 11 or 13 metres.A building permit will be needed for the foundation. Involved in this will be engineer’s drawings forthe foundation specifically for your soil type and wind Zone.Lines companies will need information drawings and connection information on the inverters. Theywill need the certificate of compliance from the electrician and declarations of conformity.Power retail companies need the compliance number from the lines company. They then send outsomeone to install a meter for you.AES has systems in place so all these details are handled simply and easily
5. Site informationThis is the critical part of the whole wind process. The amount of wind determines the overallsystem budget, it also determines if the whole process is worthwhile. We have in a lot of caseschange potential wind jobs to solar as they haven’t the wind resource to cope with the potentialload.Step 1 How much wind do I have?We use three systems to determine the potential wind energy at your site.1. Measure (recommended) we use power predictor wind monitors on site at a cost of 310 a unitplus GST to measure and record your wind energy for a month to a year. If we do a month weanalyse data from other local wind stations to give us a guide on the amount of likely wind wewill get over the course of a year2. Trees (Griggs Putnam index attached) determines the average wind by the deformity of the treeslocallyTop View ofIndexSide View of Plant Description of Deformity Wind SpeedOIIIIIIIVVVIVIIPlantNo DeformityNo SignificantBrushing and SlightFlagging7-9 Miles perHour9-11 MPHSlight FlaggingModerate Flagging11-13 MPHComplete Flagging13-16 MPHPartial Throwing15-18 MPHComplete Throwing16-21 MPHCarpeting22 MPH3. Where do we site the turbine? We use some simple mapping tools to see the effect of placingturbines on site, its useful for trees structures and terrain info
Step 2 How Much energy do you use?We also determine the amount of energy you use on site, either by your power accounts or adetermination of what potential appliances and energy loads you have on site. We have anevaluation spread sheet to make this process easyStep 3 Match the load wind speed and turbineMatch the load, wind speed to a turbine and price the system. We have a good idea of what areasare suitable for wind. We however cannot right off any site because there is significant wind inplaces from the top to bottom of New Zealand. Using simple analysis is the easiest option.6. EconomicsThe amount of wind you have determines the amount of energy produced by the wind turbine.A 4kw wind turbine in 5m/s wind for grid tie will produce less than 500 watts on average whereas at7m/s it could be closer to 1KW or 24kwhrs of energy a day.The associated costs of wind turbines, the foundations, Electrics, Poles, Wind Turbine, Consents,Assembly and installation can add up to a significant sum.Factors that contribute to the take-up of wind turbines verses other generation High wind area 8m/s wind and aboveSupplementary to other generationSome infrastructure already availableUse of larger wind turbines 10KW plusLook and aesthetic of the turbine as well as what the turbine representsWind Turbines add to some people the appeal of independence and in some areas reasonablegeneration, if the numbers and wind speed line up we have the wind solutions to meet your budget.7. SummaryWind turbines are a fantastic source of energy if the resource is available. Arguably they can lookgreat as well and gives you the independence of relying less on the power utilitiesIf the costs seem prohibitive we have cost effective solar solutions for most applicationsPlease contact Advanced Eco Solutions for more information

Wind energy is generated by a wind turbine which converts the kinetic energy of wind into electrical energy. The system mainly depends on speed of the wind to enhance the performance the turbine in mounted on a tall tower. Wind energy conversion system has a wind turbine, permanent magnet synchronous generator and AC-AC converter. As wind .

the adoption and adaptation of agile software development practices. This model was found especially useful when the project context departs significantly from the “agile sweet spot”, i.e., the ideal conditions in which agile software development practices originated from, and where they are most likely to succeed, “out of the box”. This is the case for large systems, distributed .
