The installation of the electric field with a frequency of power line is described in this paper. The modelling we preferred in this work has parallelepipeds analogous to the human body. The power line derived by the finite element is presented for the electric field distribution. The human body is considered a model to allow stream density that can permit the values for the strength of fields with some standards. Read More Read Less

Abstract We need a stable power system operation for reliable and quality power distribution. The system operation mode is prone to disruptions such as short circuits, and outages of large generating units and transmission lines, which cause parameter changes in the electric systems. The changes may lead to the emergence of electromechanical oscillations in synchronous generators reflected in the fluctuation of... We need a stable power system operation for reliable and quality power distribution. The system operation mode is prone to disruptions such as short circuits, and outages of large generating units and transmission lines, which cause parameter changes in the electric systems. The changes may lead to the emergence of electromechanical oscillations in synchronous generators reflected in the fluctuation of the parameters such as rotational speed, active and reactive power, voltage, and power output. In this process, it is possible to expect oscillations that can compromise the stable operation of the synchronous generator and the power system. The ideal method is to reduce the oscillations to use a stabiliser of the power system as an integral part of the excitation systems of generators. The excitation system can help the power oscillation stabiliser to complete the task. In the current work, we design the contemporary power system stabilizers and tested it using a finite illustration to measure the transient stability. Read More Read Less

Abstract In this paper, we conducted energy efficiency research in selected Small and Medium Enterprises of some industries. We aim to introduce energy efficiency in the industrial system. Finding suitable solutions to minimise energy consumption to reduce CO2 emissions is imperative. It is possible if the thermoelectric way generates electric energy.

We aim to introduce energy efficiency in the industrial system. Finding suitable solutions to minimise energy consumption to reduce CO2 emissions is imperative. It is possible if the thermoelectric way generates electric energy. We have detected the technical failures in the analysis, which may help optimise the energy use in small and medium enterprises. We advocate utilising this study’s applications in other industrial systems when the proposed energy efficiency is optimum. Read More Read Less
