Enejoreenejor@cstp.nasrda.gov.ngFolashade M. Dahunsifmdahunsi@futa.edu.ngKayode F. Akingbadefakingbade@futa.edu.ngIbigbami O. Nelsonionelson2000@gmail.com<div><span lang="EN-US">This study compares the result of the PID controller to the LQR controller when used in the on-orbit stabilization of a satellite in the low earth orbit. The results from the PID controller show that the controller is too weak when used alone as the controller could not stabilize the system after 500 s which is not even allowable in practical application. For the LQR controller, a performance metric was set which is: i. the settling time is to be ≤ 10 seconds, ii. Maximum power consumption ≤ 1.5 Watts and iii. Zero (0) steady-state error / final value. The LQR controller meets system performance by achieving a settling time of roll (peak amplitude=0.26 s, settling time=10.0 s), Pitch (peak amplitude=0.395 s, settling time=5.52 s), Yaw (peak amplitude=0.350 s, settling time=5.52 s) and Total power consumption are 1.26 watt with a maximum torque of 3.22 mNm. Because power consumption and precision are critical in satellite applications, particularly military surveillance satellites. As a result, for an aerospace engineer to achieve their space mission, for instance, space mission like low earth orbit surveillance satellites, flexible solar panels, a high accuracy pointing accuracy, it will be impossible to adopt a PID controller except the engineer is ready for the complexity of design filters and compensators. An LQR design in this study can take care of all this complexity with minimum power consumption.</span></div>2023-05-19T00:00:00-04:00Copyright (c) 2023 Emmanuel U. Enejor, Folashade M.

After the excavation of SF6 and reports on its application in electric power equipment and recently related literature, inspiring the author to summarize - the unique characters of SF6 and the arc suppression and operation principle, and explained some proper terms on the nameplate of the circuit breaker, all those combine an article, which can be prone to understand, at the same time it is easy to navigate of international journal on the website. In addition, for the abnormal situation of the connecting circuit breaker between the two busses in the substation, the "time constant" formed by the equivalent resistance and inductance value of the DC component of the zero-sequence fault current is related to the breaking time of the circuit breaker. Finally, combined above mentioned character with the points that must be paid attention to maintenance and being repaired on SF6 breaker in during, those things will be compiled into an article, which can be used as a reference for technical personnel in the field of power engineering.</span></div>2023-05-11T00:00:00-04:00Copyright (c) 2023 Ming Jong Linhttps://ejece.org/index.php/ejece/article/view/507Design and Viability Assessment of Grid-Integrated Solar PV System for Electric Power Supply Enhancement: A Case Study of Idofian, Nigeria2023-02-24T12:40:23-05:00Jelili Aremu Oyedokunoyedokunjelili@yahoo.comEmmanuel Taiwo Fasinaoyedokunjelili@yahoo.comBankole Adebanjioyedokunjelili@yahoo.com<div><span lang="EN-US">Recently, the demand for electric power supply has tremendously increased and the Nigerian government is unable to meet this demand, with conventional energy generation, due to myriads of issues in the electricity sector. A 2 MW grid-integrated solar photovoltaic system design is carried out in this work using Idofian, Kwara State, Nigeria, as a case study. The feasibility study for the Solar PV system along with the load estimation for the study area were done using RETScreen software. The simulation results revealed that the design is feasible for Idofian township, with an annual energy yield of roughly 2,853 MWh, of about 17% of Idofian's annual (daily) electricity consumption. Solar PV electricity generation saves around 1,182.7 tonnes of CO<sub>2</sub>. The plan, if adopted, will go a long way toward alleviating Nigeria's electricity shortage.</span></div>2023-05-19T00:00:00-04:00Copyright (c) 2023 Jelili Aremu Oyedokun, Emmanuel Taiwo Fasina, Bankole Adebanjihttps://ejece.org/index.php/ejece/article/view/513Human Physiological Condition Monitoring System based on Microcontrollers2023-03-11T09:57:07-05:00Amitave Sahazxzhering@163.comXiuzai Zhangzxzhering@163.comBappi Chandra Sahazxzhering@163.comSunit Mistryzxzhering@163.com<div><span lang="EN-US">With the rise in living standards, people are increasingly focusing on their health, and monitoring their physiological condition has become a popular trend. Sudden illnesses or hidden chronic conditions can cause abnormal fluctuations in temperature and heart rate, which can be difficult to detect without continuous monitoring. The main objective of this project is to develop a cost-effective and efficient system to monitor vital signs such as heart rate, body temperature, and steps taken, based on systematic experimental studies. The system utilizes a pulse sensor DS18B20, and ADXL345 to monitor the heart rate, body temperature, and motion status of the human body. The circuit and the HC-05 work together to transmit the detected data from the sensor to the MCU, which further transmits it to the LCD1602 or mobile phone interface for real-time display. The system provides a user-friendly interface and real-time monitoring, making it easier for individuals to keep track of their health status. This paper presents an innovative approach to human physiological condition monitoring using a microcontroller-based system, which has significant potential for improving healthcare by enabling early detection and prevention of medical conditions, ultimately leading to better quality of life.</span></div>2023-05-13T00:00:00-04:00Copyright (c) 2023 Amitave Saha, Xiuzai Zhang, Bappi Chandra Saha, Sunit Mistryhttps://ejece.org/index.php/ejece/article/view/526Power System Stability Improvement Based on Virus Particle Swarm Optimization Algorithm2023-04-05T07:35:10-04:00Payam Qaderi Babanpayamb4@gmail.comFarzad Mirfmir@cougarnet.uh.eduFarshad Ebrahimifebrahi3@cougarnet.uh.edu<div><span lang="EN-US">This article discusses the development of a Power System Stabilizer (PSS) utilizing the Virus Particle Swarm Optimization Algorithm (VEPSO) to enhance power system stability. PSS is commonly used in the industry to suppress power system oscillations. The proposed algorithm was implemented on a Single Machine Infinite Bus (SMIB) system, and the PSS controller coefficients were optimized using VEPSO. The system was simulated under a specific disturbance in the generator input power, and the generator's dynamic responses were presented. The VEPSO algorithm's results, such as faster convergence, were compared to the ICA algorithm. The simulation results demonstrate that the recommended PSS significantly improves the power system's oscillation damping performance.</span></div>2023-05-23T00:00:00-04:00Copyright (c) 2023 Payam Qaderi Baban, Farzad Mir, Farshad Ebrahimi
