Rapid Reserve Generation from a Francis Turbine for System Frequency Control
energies Article Rapid Reserve Generation from a Francis Turbine for System Frequency Control Dean R. Giosio 1,*, Alan D. Henderson 2, Jessica M. Walker 1 and Paul A. Brandner 1 1 Australian Maritime College, University of Tasmania, Launceston 7250, Tasmania, Australia; [email protected] (J.M.W.); [email protected] (P.A.B.) 2 School of Engineering & ICT, University of Tasmania, Hobart 7005, Tasmania, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-3-6324-9489 Academic Editor: K.T. Chau Received: 24 February 2017; Accepted: 31 March 2017; Published: 7 April 2017 Abstract: The increase in contributions from non base load renewables, such as wind and solar, can have adverse effects on the stability of an electrical grid. In this study, the possibility of rapidly loading a Francis turbine from a tail water depression (TWD) mode for providing additional system frequency control is investigated. Based on the analysis of full-scale TWD test results and key findings from the transient testing of a micro-hydro scale turbine unit, a detailed description of the TWD transition process is given. The formulation of an improved turbine model for use in one-dimensional hydro-electric plant models is presented with simulation results compared to full-scale data. The analytical model, which calculates output power according to the conservation of angular momentum and identified sources of loss, is used in parallel with full-scale and model scale test observations to elucidate the events and mechanisms occurring during this proposed transition. The output response, in terms of active power, was found to be highly dependent on guide vane opening rate in both full-scale and model tests. -
Water Management in the Anthony–Pieman Hydropower Scheme
Water management in the Anthony–Pieman hydropower scheme Pieman Sustainability Review June 2015 FACT SHEET Background The Anthony–Pieman hydropower scheme provides a highly valued and reliable source of electricity. The total water storage of the hydropower scheme is 512 gigalitres and the average annual generation is 2367 gigawatt hours. Construction of the Anthony–Pieman hydropower scheme has resulted in creation of water storages (lakes) and alterations to the natural flow of existing rivers and streams. The Pieman Sustainability Review is a review of operational, social and environmental aspects of the Anthony–Pieman hydropower scheme that are influenced by Hydro Tasmania. This fact sheet elaborates on water management issues presented in the summary report, available at http://www.hydro.com.au/pieman-sustainability-review Water storage levels in the Anthony–Pieman Water levels have been monitored at these storages since hydropower scheme their creation in stages between 1981 and 1991. The Anthony–Pieman hydropower scheme includes eight Headwater storages: Lake Mackintosh and Lake water storages, classified as headwater storages (Lakes Murchison Mackintosh and Murchison), diversion storages (Lakes Lakes Mackintosh and Murchison are the main headwater Henty and Newton and White Spur Pond) and run-of-river storages for the Anthony–Pieman hydropower scheme. storages (Lakes Rosebery, Plimsoll and Pieman). Lakes The water level fluctuates over the entire operating range Murchison, Henty and Newton and White Spur Pond do not from Normal Minimum Operating Level (NMOL) to Full release water directly to a power station; rather they are Supply Level (FSL) (Figures 1, 2). used to transfer water to other storages within the scheme. -

Implications for Tasmanian Electricity System of The
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. -
Groundwaters in Wet, Temperate, Mountainous,Sulphide-Mining Districts
Groundwaters in wet, temperate, mountainous, sulphide-mining districts: delineation of modern fluid flow and predictive modelling for mine closure (Rosebery, Tasmania). by Lee R.

Evans Date: ii Abstract There are as yet few studies of the hydrogeology of sulphide-mining districts in wet, temperate, mountainous areas of the world. This is despite the importance of understanding the influence of hydrogeology on the evolution and management of environmental issues such as acid mine drainage (AMD). There is a need to determine whether the special climatic and geological features of such districts result in distinct groundwater behaviours and compositions which need to be considered in mining impact studies. -

Conditions Favouring Growth of Fresh Water Biofouling in Hydraulic Canals and the Impact of Biofouling on Pipe Flows
Conditions Favouring Growth of Fresh Water Biofouling in Hydraulic Canals and the Impact of Biofouling on Pipe Flows By Xiao Lin Li BEng(Hons.) Submitted in fulfilment of the requirements for the Degree of Masters University of Tasmania October 2013 Declaration of Originality This thesis contains no material which has been accepted for a degree or diploma by the University or any other institution, except by way of background information and duly acknowledged in the thesis, and to the best of candidates knowledge and belief no material previously published or written by another person except where due acknowledgement is made in the text of the thesis. …………………………………… Xiao Lin Li Date: 12/10/2013 Statement Concerning Authority to Access This thesis may be made available for loan and limited copying in accordance with the Copyright Act 1968. …………………………………... Xiao Lin Li Date: 12/10/2013 ii Abstract Abstract Biofouling increases frictional resistance and slows the water flow in fresh water canals and pipes. It results in up to 10% reduction in the flow carrying capacity in hydropower canals in Tasmania, Australia. This project investigated the effect of colour on the growth of biofouling in open channels and the impact of biofouling in pipes and penstocks. The effect of substratum colour on the growth of biofouling was studied by submerging mild steel plates painted with four different coloured epoxy coatings in fresh water. The plates were placed in a concrete lined canal for a period of time to allow biofouling to grow. Results show that black was the favoured colour for the growth of biofouling whereas the white plates developed the least amount.
