  • Wind Turbine Write Up
    Jankowski 1 Wind Turbine Write up By: Matt Jankowski EDSGN 100 Sec 014 Windmill Background Wind turbines are an essential tool for capturing natural energy and are very simple to understand the mechanisms behind. It’s as simple as instead of using electricity to create wind, such as a fan or an AC unit, wind turbines use wind to create electricity. Humans have used wind to power mechanisms and toys for decades, such as setting sail on a sailboat to flying a kite on a windy day. Then we took those ideas and turned it into a way to create energy. The rotor blades on windmills act as the blades on a helicopter and are set at 20 degree angles, which will produce the most rotor rotation. When the wind blows, it catches on the blades and causes the rotor to spin. The rotor is either directly connected to or connected through a series of gears to a generator. The generator runs, produces electricity and stores it to be used. My Windmill My solidworks model consists of eight different parts, assembled together to make a free-standing horizontal windmill. First, I started by connecting the base and the lower mast with three mates: concentric, coincident and front plane-front plane coincident. I then added the upper mast and swivel shaft, using three mates to add them to the assembly. Next, three blades, the hub and the main shaft were added. To assemble the blades into the hub, I had to make three mates: concentric, coincident, and a 20 degree angle between the right plane and the flat surface of the blade.

Guy Barnett, MP Minister for Energy Department of State Growth 4 Salamanca Pl Hobart TAS 7000 Dear Minister Barnett Re: Response to the Draft Tasmanian Renewable Energy Action Plan Goldwind Australia (Goldwind) is pleased to present this response to the Tasmanian Governments Draft Renewable Energy Action Plan. Goldwind has over ten years’ experience of building renewable energy projects across Australia, with 562MW operating including the 144MW Cattle Hill Wind Farm in Tasmania, 960MW of wind farms currently under construction and a further 1.3 GW in the immediate development pipeline. As an experienced renewable energy developer, Goldwind shares the vision expressed in the Tasmanian Renewable Energy Action Plan and applauds the goal of achieving a 200% renewable energy target by 2040. We consider this long-term vision will bring substantial economic, social and environmental benefits for Tasmanian. We have made several suggestions that Goldwind considers would help achieve the stated goals in an efficient and effective manner. These are detailed in our submission, which is attached as Attachment A. We will continue to pursue opportunities for further renewable energy generation in Tasmania.

    Backroad Connections Pty Ltd ABN: 64 090 245 382 [email protected] (0407) 486-651 www.backroad.com.au Implications for the Tasmanian electricity system of the proposal to restore Lake Pedder July 2019 Overview The paper analyses the implication for the Tasmanian electricity system of the proposal by the Lake Pedder Restoration Committee (LPRC) to restore the original Lake Pedder. It provides information on the current contribution of the Gordon Scheme to Tasmanian electricity generation and energy storage and provides some information and estimates on alternatives to replace this generation if the original Lake Pedder was restored. Background The original Lake Pedder was flooded in 1972 as part of an expansion of the Tasmanian hydro-electric scheme. The flooded area created is still officially known as Lake Pedder although the LPRC prefer the name Huon- Serpentine Impoundment. In this paper we will use the term ‘new Lake Pedder’. The new Lake Pedder at 242 sq km is vastly bigger than the original Lake Pedder at 10 sq km. The new Lake Pedder does not have its own hydro-electric generation. Its purpose is to trap and raise the level of the water that would otherwise flow down the Huon and Serpentine rivers. The water is raised to the level where it flows through a channel created at McPartlan Pass into the Gordon Dam and contributes to the storage and generation of the Gordon Scheme. As a result the level of the new Lake Pedder does not vary more than a few metres. This makes it more visually attractive and more suitable for recreational use than the adjacent Gordon Reservoir.

  • Wind Turbine Report
    Wind Turbine Report Horizontal Axis Wind Turbine( HAWT ) -What is wind Turbine? -A wind turbine is a device that converts the wind's kinetic energy into electrical energy. -What is it looks like? - (↓The picture of wind turbine listed below↓) I did a wind-turbine assembly in solidworks, and the following pictures basically show each part of the structure of a wind turbine. (Base↑) (lower mast↑) (upper mast↑) (hub↑) (blade↑) (Nacelle↑) Assembling the parts shown above, I got the wind-turbine assembly, which looks like the picture below. (←My turbine in Solidworks) (↑Multi-view graph for mu wind turbine↑) Darrieus wind turbines -What is the Darrieus wind turbine? -The Darrieus wind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from the energy carried in the wind. The turbine consists of a number of curved aerofoil blades mounted on a vertical rotating shaft or framework. The curvature of the blades allows the blade to be stressed only in tension at high rotating speeds. There are several closely related wind turbines that use straight blades. This design of wind turbine was patented by Georges Jean Marie Darrieus, a French aeronautical engineer; filing for the patent was October 1, 1926. There are major difficulties in protecting the Darrieus turbine from extreme wind conditions and in making it self-starting. -What does it look like? -The photo of Darrieus wind turbine and my solidworks picture of Darrieus wind turbine are listed below. -What are the advantages of Darrieus wind turbine? - (1) The rotor shaft is vertical. Therefore it is possible to place the load, like a generator or a centrifugal pump at ground level.

  • Dear Ms Gardner
    Select Committee on Wind Turbines Submission 208 - Attachment 1 [Reference No] Ms.Ann Gardner By email to: Dear Ms Gardner, Thank you for your email to the Chair of the Clean Energy Regulator, dated 18 November 2014, making a formal complaint about noise and vibration from the Macarthur Wind Farm. The matters raised by you are more appropriately addressed to the Victorian Department of Transport, Planning and Local Infrastructure (formerly known as the Victorian Department of Planning and Community Development). They are not matters that fall within the powers of the Clean Energy Regulator (the Regulator) under the various Commonwealth legislation administered by the Regulator. The Clean Energy Regulator is an economic regulator. With respect to the Renewable Energy Target, the Regulator regulates both the supply of certificates (by ensuring the integrity of their creation by renewable power stations) and the demand and surrender of those certificates (by ensuring liable electricity retailers surrender the correct number of certificates). The Clean Energy Regulator is only empowered to administer relevant Commonwealth laws (eg to ensure that a wind farm operator complies with its responsibilities under relevant Commonwealth legislation that the Regulator administers). It cannot interfere in state-based activities. If a wind farm is not complying with State/Territory laws (eg as to planning requirements and noise control etc), it is a matter for the relevant State/Territory a.uthority to address. The Macarthur Wind Farm is an accredited power station under the Renewable Energy (Electricity} Act 2000 (the Act) and the Renewable Energy (Electricif:W Regulations 2001 (the Regulations). Once an eligible power station has been accredited, it remains accredited unless the Regulator decides to suspend the accreditation under Division 11 of Part 2 of the Act {being sections 30D and 30E and the circumstances prescribed for the purposes of subsection 30E(5) in regulation 20D of the Regulations).
