Conveyor belts are used in industries such as electro-mechanical and mechanical assembly to transfer goods from one position to another or from one procedure to another. In coal mining industries, controlling the speed of a conveyor can be achieved by controlling the speed of its drive unit. The Programmable Logic Controller (PLC's) commonly used programming language has the trapezoidal chart language, Ladder Diagram (LD), the Smooth Functional Diagram (SFC), and the Function Block Language (FBD). The four-level leather belt conveyer control system belongs to the model of sequential control and therefore mainly uses the SFC to program. A Programmable Logic Controller (PLC) is used to implement the control strategy. A PLC is a microprocessor-based control device with the original drive of complementing relay logic. The latest PLCs have progressed past just a robust stage into a new realm of high computational control and processor speediness. These, along with the PLC's extremely elastic arrangement, make it an ideal stage for uses far beyond its conventional ones. The main aim of this paper is to design a PLC conveyor belt control system for silo operation that has three various modes, namely continuous mode, manual mode, and fill by pass mode. The conveyor belt plays a very effective role as it reduces the time required to complete a large amount of work and increases productivity with high efficiency. It also saves money and costs, reduces the required manpower, is characterized by ease of maintenance and handling, and offers many other benefits.
The Single Linear Induction Motor (SLIM) is a specialized electrical machine that produces linear motion instead of the rotary motion produced by a traditional rotary induction motor. SLIM's accurate dynamic model is required to analyze the performance of the motor under different operating conditions. Dynamic modelling of SLIM using the traditional DQ- axis equivalent circuits is difficult due to the time-varying parameters such as end effect, air gap flux, saturation, and half-filled slot. The two methods for modelling SLIMs were compared, namely the conventional method and the split method. The results of the comparison showed that both methods provided similar results, but the split method offered a more detailed analysis of the components and provided deeper insight into the behavior of the motor. The choice between the two methods depends on the specific requirements and objectives of the analysis. In this paper, the dynamic model of SLIM is modelled using conventional and split methods in MATLAB/SIMULINK. The results of the two modelling methods are compared with each other, and it is concluded that the splitting method provides better transient performance than traditional D-Q axis methods.
The performance of a perovskite photovoltaic cell based on an active layer of molybdenum trioxide and methyl ester was studied, and the results are described in this research. The FTO/MoO3/perovskite layer/PC60bm-Au is a "Fluorinedoped Tin Oxide: Molybdenum Trioxide: Perovskite Layer: PC60bm (a polycarbonate-based material) and Gold" structure that was subjected to electrical simulation using the General-Purpose Photovoltaic Device Model (GPVDM) software. The effect of series resistance and layer thickness on Power Conversion Efficiency (PCE) and Fill Factor (FF) in a Perovskite Solar Cell (PSC) based on an absorbing layer was examined using the GPVDM program. Adjustments were made by varying the values of series resistance and layer thickness. The results demonstrate that changing the value of series resistance and layer thickness can boost Power Conversion Efficiency (PCE). In this case, it resulted in an increase in Power Conversion Efficiency from 17% to 21% and an improvement in Fill Factor from 66% to 72%.
Harmonics have become an important issue as the number of non-linear elements and electronic devices coupled to electrical power systems increases by the day. A Fixed Capacitor Thyristor Controlled Reactor (FC-TCR) is widely used in power systems to continuously control reactive power. This paper presents the harmonic analysis of a three-phase FC-TCR under different operating conditions using the Dynamic Harmonic Domain (DHD) technique. The existing Harmonic Domain (HD) method is widely used to obtain the steady-state harmonics in the power grid. It is not possible to calculate transient harmonics using the harmonic domain method. The dynamic harmonic domain technique also provides a solution for the transient condition. The three-phase FC-TCR is simulated in a MATLAB environment and calculates transient harmonic quantities such as apparent power S(t), reactive power Q(t), real power P(t), and distortion power D(t), RMS values, and distortion factors of the three-phase FC-TCR when subjected to voltage disturbance.
Extreme weather events, such as hurricanes, heat waves, and winter storms, can have a significant impact on power systems, leading to power outages and disruptions in service. This review aims to optimize power system operations to enhance resilience and minimize the impact of extreme weather events. The review will include the development of advanced modelling and simulation tools to analyze the impact of extreme weather events on power systems. These tools will be used to evaluate the performance of different power system configurations and identify vulnerabilities. Additionally, the review will investigate the potential of distributed energy resources, such as micro-grids and energy storage systems, to enhance power system resilience. The effectiveness of different control and protection strategies will also be evaluated. The review will provide valuable insights for power system operators and regulators in the planning and operation of power systems to withstand extreme weather events. Ultimately, the review will contribute to the development of a more robust and resilient power system, ensuring reliable and safe power supply to customers.
