This paper introduces a design and implementation of three methods to control a two SMs using Programmable Logic Controller (PLC). These methods are: wave, half, and full Stepping Excitation Method (SEM). The speed, number of rotations, and direction (Bidirectional) of SMs are manipulated in each one of these methods. Experimentally, Siemens LOGO! 230 RC (as a basic PLC unit), with the aide of Digital Module LOGO! DM8 230R (as an expansion module) has been used in our work. LOGO! Soft Comfort Version 8.2 has been used to build our algorithms for the speed, displacement of rotations, and direction control of SMs. Function Block Diagram (FBD) semantic design program is employed to achieve the proposed PLC controller programs for SMs. This paper highlights the simplicity of possibility to control the SMs by using any type of the SEMs based on PLC . Using the PLC will save electronic components used in the drive circuit because it is not required any interface circuit linking the PLC and the SMs, as a result this will minimizing the cost and develop the whole reliability of the controller.

It has being increased constantly with the expansion of energy consumption via traditional energy sources which are depleting. The world has needed to turn to alternative energy, which is represented by renewable energy. The most important and most efficient of these is solar energy, and to get the maximum value of this energy with the highest efficiency, there should be direct monitoring of the performance of these solar panels. So, in this study, the Internet of Things (IoT) was used as a remote monitoring system to obtain the main factors like load current, terminal voltage, consumption power, temperature, humidity, and light intensity. The values were real and accurate, depending on the use of Adriano and sensors to measure the above-mentioned determinants and then using Wi-Fi technology to send the data that was processed in the circuit. Then the thing speak platform was used to display, analyze, and stor...

Microcontroller mega type Arduino used as a controller for producing the gate pulses. The optimized switching angles determination results in wide range of output voltage. Depending on number of switching angles, the lower order harmonics (LOHs) can be eliminated to improve the output voltage waveform. A comparison study using MATLAB/Simulink for sinusoidal-PWM and SHE-PWM techniques, which shows for the same LOH in the output voltage waveform, the SHE-PWM has less number of pulses per half cycle than sinusoidal-PWM strategy. The reduction in number of pulses results less switching losses. The simulation done using ten switching angles to drive R-L load. A prototype of SHE-PWM inverter with R-L load is used to validate the simulation results.

As a result, it's one of the primary causes of excessive energy costs and power outages. This paper aims to present a simple, cost-effective, and accurate PF metering and monitoring system implemented using an Arduino microcontroller with a novel methodology different from other papers. The proposed method is to design the software code instead of using external components of Zero-Crossing Detectors (Z-CDs) for both voltage (V) and current (I) signals, and instead of using Exclusive-OR (X-OR) gates also. Determining the phase-angle and PF in an efficient manner can be useful in many approaches to electrical systems: 1-for synchronization of parallel connections of alternators; 2-for directional protection systems; 3-for PF correction and load management; and 4-for designing watt/ene...

The thesis details the conceptualization and execution of two distinct architectures for PV applications. The first architecture focuses on a data monitoring apparatus for PV panels, utilizing a PLC S7-1200 programmable logic controller and incorporating five different data visualization methods. This system includes various sensors and instrumentation to monitor the performance of solar panels, such as temperature, current, voltage, and irradiance sensors. The second proposed architecture involves using the PLC S7-1200 to regulate a DC-DC boost converter while interfacing with the SCADA interface. The DC-DC converter transforms the variable voltage output from the PV array into a consistent voltage suitable for different applications. The system utilizes a PID controller and a PWM controller to continuously adjust the PWM duty cycle value of the boost converter based on feedback from sensors and predefined setpoints. The SCADA interface facilitates performance monitoring and provides a user-friendly interface for system control. The PLC S7-1200 serves as the central controller, programmed using the TIA Portal V17 software, and collects data from the solar panels through analog input modules. The collected data is processed, analyzed, and stored in a database for further exploration and visualization.
