The project developed and trialed a method of mapping ecosystem functions in South East Queensland using biophysical data layers in preference to land use surrogates. Biophysical data and surrogates were identified for 19 ecosystem functions and maps were produced for each. Data layers for each ecosystem function were standardized for mapping purposes using existing expert advice or data quantiling. Two versions of the total ecosystem function overlap maps were also produced, showing areas of high ecosystem function that have the potential to contribute to high ecosystem service provision. This method was successfully used to replace land use surrogates in most cases, and produced maps that planners and decision makers considered credible. The mapping exercise allowed an ecosystem services framework (the SEQ Ecosystem Services Framework) to be embedded in a statutory planning document, used in a State of the Region Report and to influence planning decisions at a local government level. © 2013 by the author(s).

Modern circuit breakers (CBS) may be susceptible to catastrophic failure possibly because they are designed to be more highly stressed than earlier CB designs with multiple interrupters per pole. Improved performance is obtained with dielectrically well-designed interrupters by taking advantage of advanced controlled switching to achieve a reignition-free window during opening to minimize the risk of nozzle puncture. On occasion, CB owners may wish to check whether equipment is performing satisfactorily and whether controllers are producing reliable and repeatable stress control. The monitoring of voltage waveforms during switching using established methods will provide information about the magnitude and frequency of small reignitions and restrikes. However, waveform measurements at a moderately high signal frequency require plant outages to connect specialized equipment. A nonintrusive measurement technique has been developed to measure the high- and low-frequency voltage waveforms occurring during reactor switching operations without the need for an outage. Results of tests performed in the laboratory and in a 275-kV substation demonstrating the capability of this new method to detect reignitions are presented. © 2012 IEEE.

Rock mass is a highly complex entity where the strength and deformation behaviour can be significantly affected by its secondary structures such as joints, fissures and bedding planes. Whilst many research works have been conducted to study the behaviour of a specific rock mass, a thorough understanding of its strength and deformation behaviour incorporating different joint sets has not been established. In this study, a comprehensive numerical modelling using a three-dimensional distinct element code, 3DEC, was undertaken to study the strength and deformation behaviour of a mudstone, locally found in Melbourne, in unconfined and confined states. The initial unconfined model established for intact mudstone was calibrated against the well-established laboratory-based empirical strength relationships and subsequently compared with some strength test data available for field samples. The intact unconfined model was then extended to study the strength behaviour in the confined state. The results obtained from this confined intact model were compared with existing strength criteria and were found in good agreement. The confined model was extended further to investigate the effects of joint sets and dip angles on the rock mass strength and deformation behaviour by incorporating two different joint configurations (one-joint and two-joint) with varying dip angles (0°-90°). This study found that the rock mass strength in a confined state varied significantly between the two joint configurations. © 2011 Saudi Society for Geosciences.

Transmission smart grids will use a digital platform for the automation of high-voltage substations. The IEC 61850 series of standards, released in parts over the last ten years, provide a specification for substation communication networks and systems. These standards, along with IEEE Std 1588-2008 Precision Time Protocol version 2 (PTPv2) for precision timing, are recommended by both the IEC Smart Grid Strategy Group and the National Institute of Standards and Technology Framework and Roadmap for Smart Grid Interoperability Standards for substation automation. IEC 61850, PTPv2, and Ethernet are three complementary protocol families that together define the future of sampled-value (SV) digital process connections for smart substation automation. A time synchronization system is required for an SV process bus; however, the details are not defined in IEC 61850-9-2. PTPv2 provides the greatest accuracy of network-based time transfer systems, with timing errors of less than 100 ns achievable. The suitability of PTPv2 to synchronize sampling in a digital process bus is evaluated, with preliminary results indicating that steady-state performance of low-cost clocks is an acceptable \pm300 ns but that corrections issued by grandmaster clocks can introduce significant transients. Extremely stable grandmaster oscillators are required to ensure that any corrections are sufficiently small that time synchronizing performance is not degraded. © 2012 IEEE.

This letter presents a technique to assess the overall network performance of sampled value process buses based on IEC 61850-9-2 using measurements from a single location in the network. The method is based upon the use of Ethernet cards with externally synchronized time stamping, and characteristics of the process bus protocol. The application and utility of the method is demonstrated by measuring latency introduced by Ethernet switches. Network latency can be measured from a single set of captures, rather than comparing source and destination captures. Absolute latency measures will greatly assist the design testing, commissioning and maintenance of these critical data networks. © 2010-2012 IEEE.

Experience has shown that HV equipment in a switchyard, particularly oil-filled instrument transformers, can fail explosively following dielectric breakdown. Failure of HV equipment can cause injuries to personnel in the vicinity due to fire and explosion, and therefore utilities implement various risk mitigation procedures. © 2012 IEEE.

In Australia, grid integration of renewable energy (RE) resources has been very popular due to public awareness of climate change and favorable government policies. The initial mandatory renewable energy target (MRET) has been successful and there has been a revised target (RET) set for next decade. On the other hand, there are some regulatory and technical issues posing hindrances to the development of renewable resources. This paper discusses the opportunities and problems associated with renewable energy integration into Australia's National Electricity Market NEM. Issues such as the regulatory frameworks, access standards as per National Electricity Rules (NER), connection process, and transmission pricing frameworks are discussed. © 2015 IEEE.

Ethernet is a key component of the standards used for digital process buses in transmission substations, namely IEC 61850 and IEEE Std 1588-2008 (PTPv2). These standards use multicast Ethernet frames that can be processed by more than one device. This presents some significant engineering challenges when implementing a sampled value process bus due to the large amount of network traffic. A system of network traffic segregation using a combination of Virtual LAN (VLAN) and multicast address filtering using managed Ethernet switches is presented. This includes VLAN prioritisation of traffic classes such as the IEC 61850 protocols GOOSE, MMS and sampled values (SV), and other protocols like PTPv2. Multicast address filtering is used to limit SV/GOOSE traffic to defined subsets of subscribers. A method to map substation plant reference designations to multicast address ranges is proposed that enables engineers to determine the type of traffic and location of the source by inspecting the destination address. This method and the proposed filtering strategy simplifies future changes to the prioritisation of network traffic, and is applicable to both process bus and station bus applications. © 2011 IEEE.

The Australian energy market operator is expecting a significant increase in wind power generation to meet the Australian renewable energy target of generating 20% of renewable energy by 2020. Along with other states, Queensland is expecting a large penetration of wind power, particularly in its northern region. In the presence of such large scale wind generation, it is important to examine its effect on stability of the Queensland network. In this paper, small-signal stability of the Queensland network has been investigated considering future wind power penetration. The wind farm is simulated by an aggregated doubly fed induction generation model. The work mainly focuses on inter-area modes. Wind power is accommodated by considering load growth and generator displacement individually for getting a useful insight into its impact on damping performance of the grid. For completeness of the study, generators equipped with stabilizers have also been displaced. The influence of wind power on system damping performance is studied and presented through eigenvalue analysis. It has been found that during the peak load condition, the inter-area Central Queensland - North Queensland (CQ-NQ) mode is largely influenced when system load is scaled up to accommodate wind power. It has also been observed that displacement of synchronous generator with stabilizers from CQ region does not have much influence on CQ-NQ inter-area modes while keeping Callide-C unit in service. © 2013 Elsevier Ltd.
