Abstract: Electricity has become not only an essential element to people’s everyday life but also the most important power source to most industries and businesses. The continuously increasing demand of electricity consumption has resulted in a consistent expansion of power grid as it was seen in the past few decades. This in turn has dramatically increased the cost of electricity during the same period in Australia. In contrast, the recently recorded low economic activities and significant growth of rooftop photovoltaic has led to a reduction in the forecasted electricity demand in Australia. This has resulted a reduced number of network augmentation projects for most electric utilities across the country. Instead, the substation refurbishment work has become the focus for most electric utilities in the foreseeable future. Such sharp turning point of trend has placed an enormous challenge in front of electric utilities on how to make the power system operation more cost effective and preserve a high level of reliability and security. In response to the challenge, the integration of advanced technologies with the existing power system has been recognised as a viable solution. The international standard IEC 61850 for substation communication system has gained momentum globally to be implemented in power utility automation systems. The flexibility and vendor independent feature of the standard inspired a range of innovative approaches for power grid projects including substation refurbishment work. This research aims to develop and verify a vendor independent device, which is named as substation event monitor, with the capability of interfacing the legacy and existing substation automation system equipment to the modern intelligent electronic devices (IEDs) over Ethernet network in a non-intrusive and cost effective manner. The substation event monitor is also equipped with the ability of providing synchronised time information at the accuracy level of ±1 microsecond over the same communication infrastructure via IEEE 1588 standard, also called the Precision Time Protocol (PTP). The created device is suitable for substation refurbishment work and has the potential in many other utility applications, such as network state estimation and substation commissioning. This thesis takes a bottom-up approach to the form of information on the construction and verification of substation event monitor. It begins with the provision of the critical review on the detailed knowledge of both international standards of IEC 61850 and IEEE 1588. This work was needed because there is lack of concise, publicly available and informative material on these complex standards for power utility engineers. The thesis is then expanded with the in-depth design information on the developed prototype of substation event monitor. Finally, the verification results of the prototype device were produced at both component level and system level in this thesis. The provision of the comprehensive knowledge of the prototype device will deliver confidence to utility engineers in considering the adoption of substation event monitor as a low cost, non-intrusive, IEC 61850 compatible and synchronised IED that meets the needs of substation refurbishment work and other potential power utility applications.
