Effect of Genetic PID Power System Stabilizer for a Synchronous Machine”,
Get PDFABSTRACT This paper focuses on the use of advanced techniques in genetic algorithm for solving power system stabilization control problems. Dynamic stability analysis of power system is investigated considering Proportional-Integral-Derivative power system stabilizer for modern power systems. Gain settings of PID-PSS are optimized by minimizing an objective function using genetic algorithm (GA). The operation of a Genetic PID with PSS controller is analyzed in simulink environment. The development of a Genetic PID with power system stabilizer in order to maintain stability and enhance the performance of a power system is described widely. The application of the Genetic PID with PSS controller is investigated by means of simulation studies on a single machine infinite bus system. Controller design will be tested on the power system to prove its effectiveness. Analysis reveals that the proposed PSS gives better dynamic performances as compared to that all of mentioned methods. The superior performance of this stabilizer in comparison to PSS and without PSS proves the efficiency of this new Genetic PID Controller with PSS controller. The comparison studies carried out for various results such as speed deviation, field voltage, rotor angle and load angle in Simulink based MATLAB environment
Particle Swarm Optimization Based PID Power System Stabilizer for a Synchronous Machine
No full textThis paper proposes a swarm intelligence method that yields optimal Proportional-Integral-Derivative (PID) Controller parameters of a power system stabilizer (PSS) in a single machine infinite bus system. The proposed method utilizes the Particle Swarm Optimization (PSO) algorithm approach to generate the optimal tuning parameters. The paper is modeled in the MATLAB Simulink Environment to analyze the performance of a synchronous machine under several load conditions. At the same operating point, the PID-PSS parameters are also tuned by Ziegler-Nichols method. The dynamic performance of proposed controller is compared with the conventional Ziegler-Nichols method of PID tuning controller to demonstrate its advantage. The analysis reveals the effectiveness of the proposed PSO based PID controller

Get PDFThe main aim of this research work is to develop and design a proto type model for a pick and place robotic vehicle with a soft catching gripper that can be controlled by android OS for remote operation. At the transmitting end using android application device, commands are sent to the receiver to control the movement of the robotic vehicle. Meanwhile at the receiving end four motors are interfaced to the microcontroller where two for them are used for arm movement while the other two are for the body movement. The android application device transmitter will acts as a remote control while the receiver end Bluetooth device is fed to the microcontroller to drive DC motors via motor driver IC for necessary work. Remote operation is achieved by any smart phone with AndroidOS; upon a GUI (Graphical User Interface) based touch screen operation. DOI: http://dx.doi.org/10.11591/telkomnika.v14i1.737
Logixpro Based Scada Simlations Model for Packaging System in Dry ICE Plant
Get PDFSupervisory Control and Data Acquisition (SCADA) systems control and monitor industrial and critical infrastructure functions, such as electricity, gas, water, waste, railway, and traffic. The main objective of this work is to develop SCADA simulation model for packaging system in dry ice plant. Dry ice is an important refrigerant for keeping foods cold and preventing bacterial growth during shipment. Dry ice used for cooling or freezing foods must be very clean and considered food grade to ensure that food it may touch will not be contaminated. Some recent developments for its use include using the pellets in blasting or cleaning and its increasing use in transporting medical specimens, including hearts, limbs, and tissues, for reattachment and transplantation. The manufacturing process of dry ice has not changed significantly in many decades and is a relatively simple process of pressurizing and cooling gaseous carbon dioxide. But because of its growing demand, packaging becomes vital. An attempt has been made to develop and automate LOGIXPRO based SCADA simulations for dry ice plant to improve packaging and extensively reduce operating labor costs
GSM based dual power enhanced LED display notice board with motion detector
No full textIn this paper, a new improved Light Emitting Diode (LED) Display notice board with GSM technology has been created to plugs in all the drawbacks in existing framework. The proposed model has an excellent display notice board to display notices or messages at places that require real-time visibility, thereby transferring messages by Short Message Service (SMS) through cellular device. The proposed work in this paper elaborately narrates the procedure to construct a display notice board that has the quality of displaying messages in continuously running mode, and enabling the user to alter the ongoing message using SMS instantaneously. This system also has the feasibility to bind with other devices such as PC or laptop. The best feature of proposed system is the dual system for changing messages. And also utilizes two way power supply such as Renewable energy (Solar Power) and AC power. This feature enables the proposed model to work under any situations which overcomes the drawback in the existing display notice boards. Additionally, a motion detector has been included which turn ON or OFF the system automatically if any motion is not sensed.</jats:p

Designing Beyond Hot and Cold - Exploring Full-Body Heat Experiences in Sauna
No full textPublisher Copyright: © 2024 Copyright held by the owner/author(s). Publication rights licensed to ACM.The design of thermal experiences, often only associated with hot and cold sensations, encompasses a much wider range of qualities that can evoke emotional and sensory effects on users extending beyond this basic binary nature. Through a phenomenological study of a traditional Finnish sauna, we delve into how individuals perceive and express full-body heat sensations using both verbal and non-verbal methods and infer dimensions and parameters of heat that can inform future thermal experience design. Findings from participants' expressions lead to formulating experiential dimensions such as the dynamic nature of heat, the aesthetics of discomfort, considerations of texture and heaviness, interoception, and personal memories that expand our understanding what heat as a design material consists of and the various possibilities it may hold. Furthermore, we propose three thermal parameters of motion, timbre, and distribution which can contribute to designing more intricate heat experiences and pave the way for further research in temperature interfaces.Peer reviewe
