“…Due to the high costs, it is impractical and unaffordable to position all buses with μPMUs, contributing to the need to assess the optimum location in the distribution system with small numbers of μPMUs. To reduce the number of μPMUs and SSSD, we have used the improved IENS model [51], which improves the observability of the distributed network, as shown in Fig. 3, by utilizing the measurements smart meters and pseudo measurements of the load powers in the distribution systems.…”

This paper proposes a SUGPDS model based on Detection and Isolation algorithm and smart sensors, namely micro phasor measurement unit, smart sensing and switching device, phasor data concentrator, and ZigBee technology, etc. for the identification, classification, and isolation of the various fault occurs in the underground power cable in the distribution system. The proposed SUGPDS is a quick and smart tool in supervising, managing, and controlling various faults and issues and maintaining the reliability, stability, and uninterrupted flow of electricity. First, the SUGPDS model is analyzed using a distributed parameter approach. Then, the proper arrangement of the system required for the implantation of SUGPDS is demonstrated using figures. The Phasor data concentrator plays an essential role in developing the detection and classification report for identification and classification. Finally, smart sensing and switching device installed at a different location isolated the faulty phase from a healthy network. This approach helps to decrease power consumption. Hence, SUGPDS has super abilities compared to the underground power distribution system. The effectiveness of the proposed method and model is demonstrated via figures and tables.

“…The proposed method uses a nonlinear programming algorithm, and obtains the minimum cost combination of µPMUs and PFMS and their placement in distribution networks. Moreover, the optimal placement of µPMU based on information evaluation and node selection strategy (IENS) by using greedy algorithm is presented in [2]. It uses the smart meters and pseudo-measurements of loads to reduce the number of µPMUs.…”

The Micro-Phasor Measurement Unit (µPMU) or distribution-level PMU (D-PMU) is a measurement device that measures the synchronized voltage and current values of electric power distribution networks. The synchronized data obtained by µPMUs can be used for monitoring, diagnostic, and control distribution network applications, so that operators can understand the dynamic states of the distribution network in real-time. In this paper, we review the state-of-the-art µPMU research which includes a list of µPMU applications, monitoring and diagnostic functions, control applications, and optimal placement of the µPMU. In addition, we analyze the benefits of µPMUs in distribution networks; in particular, their reliability and resiliency, cost savings, and environmental and policy benefits.

Introduction: Aspects of power system protection which contributes to mal-operations and blackouts can be improved by supervision of system behavior and response based analysis rather than condition-based or event-based analysis using wide area measurements based on synchrophasor technology. The paper explores the application of micro-Phasor Measurement Unit for time synchronized real-time distribution network monitoring and agile decision support schemes for system prognosis and control. Case description: The scheme is proposed as part of a project on "Power System Voltage Stability Analysis using synchrophasors in Distribution System of Kerala Grid" at Kerala State Electricity Board Ltd. An actual grid occurrence during the severe tropical cyclone Ockhi, is considered as the base case which motivated the work. Discussion and evaluation: A voltage stability index (VSI) based special protection scheme (SPS) for radial distribution network at a proposed smart city is presented in the present study. The proposed special protection scheme on actual implementation can use data from proposed local micro-Phasor Measurement Unit. The PMU is proposed to be placed at one of the key nodes of the distribution system network in the city. Conclusion: The VSI is derived using local phasor values and is used to initiate a Special Protection Scheme for N-1 contingency at the key node, so as to ensure availability of the most essential feeder which provides supply to a hospital campus housing several health institutes of prime importance. The voltage stability index derived is tested and SPS is validated using real-time grid data.
