With the growing adoption of solar photovoltaic (PV) systems, developing effective fault detection techniques is crucial to ensure high efficiency and reliability. This paper presents a wireless PV fault detection system where the solar field is divided into sectors, each containing multiple PV cells. After applying test signals, each cell's/panel status is identified as normal operation, short circuit, open circuit, or misalignment. The test data is encoded into protocol frames using binary encoding and Hamming error correction coding implemented in Field Programmable Gate Arrays (FPGA). This enables single-bit error detection and correction during wireless transmission. NRF24 modules transmit the encoded data between the solar field and the central control station. The received data is Hamming decoded, and the protocol frames are extracted to identify and localize faults to specific cells/panels. Experimental validation on a 4-module laboratory setup demonstrates 99.2% fault detection accuracy with an average detection time of 77.7 ms. The system achieves a 4.3 dB coding gain in wireless transmission through Hamming (14,10) error correction. Statistical analysis confirms system reliability with significance at p < 0.001. This wireless monitoring approach offers centralized identification of faults across distributed solar installations, improving operational efficiency and system reliability.

The turbulent airflow caused by vehicular movement on highways is a source of kinetic energy for wind energy (WE) that can be utilized to power highway lighting and communications. The purpose of the current work is to design, install and measure the extent of benefit from small wind turbines along a Highway (HW) in one of the governorates of Iraq - Dohuk. In this investigation, wind speed measurements are close to a significant HW on the Dohuk-Zakho-Iraq (DZI) Road. The three positional characteristics are examined for the wind turbines' optimal position. These factors are heights above ground level, lateral distances from the road shoulder, and the wind turbines' highway-facing orientation. It is possible to supply electrical power for side lighting of external roads via vertical axis wind turbines (VAWT), which are produced from disturbances in air movement. In addition, a battery pack has been used to store energy to sustain fluctuations caused by stopped vehicle traffic and to ensure load operation in the event of a wind turbine stop. A 500W capacity vertical axis windmill is being worked on. The suggested landscaping technique has generated exceptional and long-lasting effects for a price of under 350 US dollars.

This paper presents a proposed design and analysis of a three-phase squirrel cage induction motor when changing of internal characteristic design for the three-phase induction motor. Two situations have been applied to enhancing the performance of the three-phase induction motor. The first situation has been implemented by changing the magnetic flux density (MFD) via the build of the six-phase for the same induction motor. The second situation has been implemented by changing core materials of the rotor part of the induction motor, like aluminum (AL) and cast iron (CI). The finite element method (FEM) has been used to analyze the rotor part, also to obtain the representation and simulation of the realty cylindrical rotor part of motor. The frequency domain (FD) analysis using to obtain the results within the environment of the COMSOL multiphysics 5.5 version

Nowadays power systems are huge networks that consist of electrical energy sources, static and lumped load components, connected over long distances by A.C. transmission lines. Voltage improvement is an important aspect of the power system. If the issue is not dealt with properly, may lead to voltage collapse. In this paper, HVDC links/bipolar connectionswere inserted in a power system in order to improve the voltage profile. The load flow was simulated by Electrical Transient Analyzer Program (ETAP.16STAGE.16)program in which Newton-Raphson method is used. The load flow simulation studies show a significant enhancement of the power system performance after applying HVDC links on Kurdistan power systems.The bus voltages are significantly increased after connecting High Voltage Direct Current.

Prosthetic devices are necessary to help amputees achieve their daily activity in the natural way possible. The prosthetic hand has controlled by type of signals such as electromyography (EMG) and mechanomyography (MMG). The MMG signals have represented mechanical signals that generate during muscle contraction. These signals can be detected by accelerometers or microphones and any kind of sensors that can detect muscle vibrations. The contribution of the current paper is classifying hand gestures and control prosthetic hands depends on pattern recognition through accelerometer and microphone are to detect MMG signals. In addition to the cost of prosthetic hand less than other designs. Six subjects are involved. In this present work is the devices. In this study, two of them are amputee subjects. Each subject performs seven classes of movements. Pattern recognition (PR) is used to classify hand gestures. The wavelet packet transform (WPT) and root mean square (RMS) as features extracted from the signals and Support vector machine (SVM) as a classifier. The average accuracy is 88.94% for offline tests and 84.45% for online tests. 3D printing technology is used in this study to build prosthetic hands.

This paper presents a comprehensive analysis of power quality for static synchronous compensator on the distribution power system (DSTATCOM) when different types of energy sources are used to supply the DC link channel of DSTATCOM. These types of power supplies have a different effect on the compensation of DSTATCOM due to operation nature of these sources. The dynamic response of the DSTATCOM has investigated that produced by individual and hybrid energy sources to evaluate the influence of these sources in terms of time response, compensation process and reduce the harmonics of current source. Three cases have been considered in this study. First the photovoltaic (PV) cells alone, second the battery storage alone, and third a hybrid coordinated design between (PV cells with battery storage) is used. A boost DC-DC circuit has connected to a photovoltaic cell with maximum power point tracking (MPPT) while DC-DC buck-boost circuit is used with a battery. High coordination between PV and battery circuits in the hybrid system is used to improve the performance. A synchronous reference frame (SRF) with a unit vector has used to control the DSTATCOM. The simulation results show that the hybrid design has a superiority response compared to the individual sources.

This paper presents, a Particle Swarm-Optimization (PSO) using Teaching Learning-Based Optimization (TLBO), and Antlion Optimization (ALO), for tuning PI controllers of the voltage regulator and current regulator for the control circuit of Static Synchronous Compensator (STATCOM). The type of STATCOM used is a 48-pulse Neutral Point Clamped (NPC) gate-turn-off thyristor (GTO)-based Voltage Source Converters (VSC). STATCOM is compensating power of up to ±10 MVAR. STATCOM control is provided based on a decoupled current strategy (d-q) using the current direct and quadrature components.

The strategy of enhancing power quality in the face of system fluctuations using STATCOM with multi-supply sources Photo-voltaic cells (PV) and the battery system on the capacitor channel of VSC converters, to provide the required power of compensation. The dc to dc boost converter has been used to regulator the power of PV cells, and the dc-dc buck-boost converter circuit has been used to regulator the power of battery energy storage. Happenings of energy quality during network perturbation or disturbance, like feeder, tripping and reclosing, and load switching were analyzed with the participation of STATCOM, so the multi-source (PV and battery) system with STATCOM suppresses these problems. A modified IEEE 12 bus test feeder with STATCOM has been used for the case study. The design and analysis have been carried out using m-file and SIMULINK for MATLAB 2015b
