Developing State Space Models for Power Tapping and Injection in Capacitor-Coupled Substations within Transmission Networks | Chapter 8 | Current Approaches in Engineering Research and Technology Vol. 9

The Capacitor Coupled Substation (CCS) is an emerging technology designed to tap electrical power from high-voltage (HV) transmission lines and convert it to distribution-level voltage using coupling capacitors. CCS has gained attention due to its potential for cost-effective power supply, especially in sparsely populated areas. A notable feature of CCS is its ability to perform both power tapping and power injection, with applications such as feeding microgrid-generated electricity back into the main transmission network. This dual functionality has motivated numerous studies, focusing on its integration into transmission networks and its impact on stability, including multiple CCS units operating in tandem. With its ability to control voltage stability through capacitive reactive power, CCS technology is seen as a feasible option for rural electrification.

This paper develops a state-space mathematical model for the CCS system under power tapping and power injection conditions, providing a framework for analyzing such systems’ behavior and performance, particularly in rural electrification scenarios and renewable energy or microgrids integration. The use of state-space formulation simplifies the complexity of multiple variables inherent in CCS systems, offering a streamlined method for effective control and design of CCS operations.

Investigating the Use for Solderless Assembly for Electronics of Some Electrically Conductive Composite Materials | Chapter 11 | Progress in Chemical Science Research Vol. 7

 Solderless congregation for electronics is a new paradigm proposed to solve the questions resulting from contradictory existing trends: the ban of the lead for one EU RoHS Directive led to an increase of the energy use and cost of the electronic products, but to a shame of reliability; therefore, an increase in wastes that comes in contradiction accompanying the depletion of materials for the VCRs industry. The increase standard for electronic products on account of an expanding IoT manufacturing requires increased dependability. In a particular approach that tried expected both natural, i.e. using generally existing photoelectric assembly line equipment, and causing trouble, i.e. manufacturing the whole assembled photoelectric module in one district, it turned out that new materials were wanted. Another electrically conductive substance is wanted to avoid the electrochemical process of copper dethroning. The paper describes the judgments of a study on two electrically conductive composite materials, as well as a plan for qualifying them for use in the result of solderless electronic modules worthy handling ultra extreme-frequency and cook signals. A practical solution search out compare the frequency act of two identical test makeups, one made for one electrically conductive composite material, and the other by copper. The approximate analysis disclosed that electrically conductive adhesives perform kind of better at high recurrences than copper in terms of insert loss and return loss in the range of 0 to 10 GHz; the sticking is a good substitute for fasten alloy to connect temperature-delicate components operating at frequency range.

Recent Development of Intelligent Shunt Fault Classifier for Nigeria 33-kV Power Lines | Chapter 9 | Newest Updates in Physical Science Research Vol. 9

 This research describes a novel way to employing artificial neural networks (ANNs) to improve transmission line protection. The suggested technique feeds four different neural network structures instantaneous voltages and currents on a transmission line during normal and fault conditions. The structures are then expertly merged to provide a system that can more effectively detect and diagnose shunt problems. The report goes into great detail about the design process as well as the many simulations that were run. The accuracy and mean square error (MSE) of the created system are examined, and the findings reveal that this approach is capable of identifying and classifying all probable shunt faults on the 33-kV Nigeria power lines in less than 1ms with a high level of precision. When evaluated under various shunt fault types with varying resistances and distances, the system's performance demonstrates that it can be used to improve distance line protection in 33-kV Nigeria power lines.
