Objectives The learning objectives are: To evaluate the year-round performance of this distribution automation technology, in terms of communications performance; behaviour during faults; and impact on CI/CMLs To consider the suitability of the communications technology for any other applications of high data rate digital radio communications in the utility sector, at the frequencies allowed in the UK To quantify the commercial benefits of Intelliteam technology for the distribution business and so provide the information needed to determine whether it is advantageous to deploy it elsewhere on the network The project will succeed if: The suitability of the new radios for providing protection functionality can be determined The performance of the technology over a 12 month period of operation can be measured and evaluated An analysis can be made of the performance of the communications sufficient to inform an assessment of their suitability for general utility applications An evaluation can be made of the benefits in terms of CI/CMLs
Abstract Many faults affecting overhead networks are transient in nature, and Distribution Network Operators (DNOs) can address this by deploying Pole-Mounted Autoreclosers (PMRs) that detect the fault, interrupt the supply and then reclose. This allows transient faults to self-clear without extended outages to the customers fed by that section of network. Standard PMRs have no situational awareness of their network position in relation to customer load, so when they trip and lockout (stay open as the fault is permanent) they remain open until reclosed by manual switching, either locally or remotely. They don’t have the functionality to understand the surrounding network and whether it could be reconfigured to minimise the outages experienced by local customers. This means that customers are subjected to longer outages while the faulted section of network is tracked down. This project aims to better understand what advanced PMRs can achieve when combined with distributed intelligence, to see whether customer outages can be reduced. Under a previous IFI project (2007_07 Distribution Automation) 32 pole-mounted Intellirupter PulseClosers, supplied by S&C Electric, were installed on eleven distribution feeder lines on the 11kV network on the southern and western half of the Isle of Wight. This project was intended to evaluate their advanced functionality, including the Intelliteam automatic post-fault circuit restoration capability which minimises the interruption of supply to customers caused by faults. Intellirupters are designed to work in teams which are actively co-ordinated so as to identify and isolate the section of a circuit on which a fault occurs, quickly and automatically restoring power to other segments of the line, and restoring the entire line when the fault clears. This advanced functionality requires high data rate peer-to-peer digital radio communications to be established between the pole-mounted devices and the substations at each end of the lines concerned. The radios installed at the outset did not deliver sufficient communications capacity and reliability to complete the evaluation of the Intelliteam functionality. New radios installed in February 2015 during the IFI project 2011_16 Advanced Radio Control, provided higher performance on one circuit, demonstrating that it is now possible to complete the deployment and evaluate the advanced functionality, The methodology of this project is therefore the deployment of commercially supplied hardware, some of which (Intellirupters) is proven in other countries, and some (the new digital radios) is on its first deployment at scale; a consultant-led analysis of the radio performance; and a consultant-led statistical analysis of the effect on our network and the quality of service performance as measured by the metrics Customer Interruptions (CI) and Customer Minutes Lost (CML).Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
