Application of power system stabilizers for enhancement of power system stability in single machine infinite bus and multi machine infinite bus by fuzzy logic controller

The power system is a dynamic and highly integrated system. Due to the large scale interconnections and highly nonlinear systems that operate in an uncertain environment where load, generator output, and operating parameter change continuously. So that it is constantly being subjected to low-frequency oscillation due to disturbance. These low-frequency oscillations cause a loss of synchronism and a breakdown of the entire system. The main function of the automatic voltage regulator is to monitor the output voltage of the generator and continuously maintain the constant terminal voltage of generator and hence it improves the transient stability of the power system. A power system stabilizer is used to generate a supplementary control signal for the excitation system in order to damp the low-frequency oscillation. The traditional solution to this problem is the application of a conventional power system stabilizer. The conventional power system stabilizer which uses lead-lag compensation where the gain setting design for the specific operating conditions is giving poor performance under different loading conditions. It is very difficult to design a stabilizer that could present good performance in all operating points of the electric power system. To overcome the drawback of the conventional power system stabilizer numerous techniques have been proposed. When the effect of power system stabilizers in damping of low-frequency oscillations in a multi-machine power system with different load combinations. If various load models considered are constant impedance load, a mixture of constant impedance, and constant current load and mixture of constant impedance and constant power load. The fuzzy logic power system stabilizer for stability enhancement of multi-machine power system. In order to accomplish the stability enhancement, speed deviation, and acceleration of the rotor of the synchronous generator of the multi-machine power system were taken as the input to the fuzzy logic controller.

Enhancing QoS in MAC layer for IoT enabled multihop mobile networks

Mobile Adhoc Networks (MANET) within the Internet of Things (IoT) framework is one of the most important wireless networks in which mobile nodes are interconnected and transmit packets in a distributed way to provide various IoT oriented services. The heterogeneity characteristic feature of IoT poses technical challenges on the MAC layer such as the increasing network traffic load, heterogeneous Quality of Service(QoS) demands. To overcome these problems, a superframe structure is designed that helps to prioritize voice and data packets and that helps to improve the performance in MANET. Within each superframe, voice packets access the channel in a contention-free period (CFP) for its transmission and data packets content for channel access in a contention period (cp). so, the maximal QoS performance is achieved by adapting to the network traffic load variations and that supports the heterogeneous QoS demands. In addition to the large coverage area, the multihop connection is enabled that helps to reduce the energy consumption of the nodes

Beam steering antenna array for multiband applications

A beam steering is mainly used in the Near field communication(NFC) devices and radio communication system. Beam steering is the process of changing the direction of the main lobe of the radiation pattern which is done by switching antenna components or by changing the phase of the signal. Low loss phase shifters can be used to perform beam steering ,by which the direction of main lobe can be controlled at THZ . The switched line phase shifters are the commonly used one which is designed by using 2 transmission lines are reference line and delay line.

A statistical approach on experimental study for determining switching frequency of retro reflector sensor using PLC

Automation is a multidisciplinary platform that involves controls and drives. Though drives and controllers build automation together without sensors it is not possible. Sensors are the vital device that interacts with the physical environment and responds to the system in the form of input. These inputs are further processed based on the predetermined programming in controllers to give the respective output via drives. Industrial sensors are broadly classified as a retro-reflective sensor, capacitive sensor, photoelectric sensor, ultrasonic sensor, and a magnetic sensor. The reliability and switching frequency of the sensor is the key factor to determine the performance of the system. In this paper, a detailed study on one such key factor named switching frequency is taken for experimental study with retro-reflective sensors. The significant study of the switching frequency and the comparison of the performance the statistical methods like descriptive statistics, correlation, and chi-square test are used.

Importance of model studies in finalizing the hydraulic design of energy dissipator and plunge pool downstream of spillway- A case study

For a number of decades, the art of hydraulic modeling has been an important tool in solving complex hydraulic problems. It entails, with a degree of sophistication that varies with the objective of the investigation, the use of a scaled model for replicating flow and fluid transport processes in diverse natural flow systems and for evaluating the performance of hydraulic structures. A lack of understanding of physical processes or complex boundary conditions in many fluid mechanics/ hydraulics problems which are not amenable by numerical or analytical techniques is investigated by physical models. Physical model studies are indispensable tools to optimize various dam components and appurtenant structures. The present paper includes one case study of a dam project in which the importance of hydraulic model studies conducted on a 1:70 scale 3-D comprehensive model for evolving the hydraulic design of spillway, energy dissipator arrangement, and plunge pool downstream of the ski-jump bucket has been discussed.
