Abstract

Increasing population growth has pressed the need to conserve potable water and protect the water bodies by keeping the rivers/ water bodies clean. Treatment of effluent is typically made by effluent treatment plant which often employs variable frequency drives (VFD) at different stages of treatment. Typically an effluent treatment plant is grid connected, bulkier and erected near industrial hubs of a large city. However, electricity unavailability in remote locations restricts installation of effluent treatment plant (ETP) at localised level. This paper proposes small capacity generation system to cater the electricity requirements of effluent treatment plant and making it energy self-sufficient. The proposed generation system employs Run-off river fed induction generator (IG) with power electronic load controller and caters a VFD fed pumps, lighting, heating appliances for the ETP. Rigorous phasor analysis, mathematical modeling and system simulations have been made which may offer minimum hardware approach at near constant frequency by effective power matching. The hardware prototype of the proposed system has been developed and experimental validation has been made using low cost DsPIC microcontroller. Performance of the system has been validated both through Matlab simulations and experimental results. The result establishes the effectiveness of the proposed control.

Abstract

Ground station antennas find their application in communication with satellites. An antenna communicates with the spacecraft by sending command signals and receiving the data from the spacecraft. Antenna dish rotates with respect to elevation axis and whole antenna structure rotates on circular track which is an azimuth axis (Gawronski, 1998).This paper discusses performance evaluation of two control algorithms on Antenna Control Servo System namely conventional PID algorithm and model based LQG algorithm. Power Pmac controller along with Power Pmac IDE and Pmac Servo Analyzer are used for implementing control algorithms. Results have been tested for single motor single drive position control system with step and ramp inputs .

Abstract

Being an integral part of any engineering system, electrical machines are used in all industries. Among all these machines, very common type of machine is induction motors. Motor faults can lead to untimely shutdown of machines and consequently lead to loss of productivity. This can be avoided by the proper detection of fault in the incipient stage itself which requires a detailed analysis of the fault and clearly understand its effect on the motor. This paper presents a method to analyses the frequently occurring rotor bearing fault on an induction motor. The fault analysis is conducted using two parameters: Stator current and voltage by Motor Current Signature Analysis and the motor flux distribution using ANSYS® Maxwell 2D.

Abstract

In this paper Speed regulation of Brushless DC motor with PI speed controller is investigated and achieved for single speed transmission which is used to drive the electric vehicle. Speed regulationof the BLDC motor is achieved not only by using the inner current control loop but also by the outer current control loop by the PI controller through sensing the speed drive cycle.Analysis of the controlling schemes modelled in MATLAB/Simulink environment using Simulink shows that the small overshoots occur not only at fully charged battery but also at 80% and 50% state of charge.

Abstract

An appreciable and significant measure of interest is currently growing up for power dc-dc converters, modernly in the industries and the civilized society and associations. In present day’s the dc-dc converters are one of the most preferred and recommended choice for the use of medium and high power utilization functions in order to achieve the objective of electronic power conversion. High voltage AC-DC, DC-AC and DC-DC converters being the essential fundamental unit of the HVDC transmission system in order to coordinate and fulfill the requirements of the power generating stations, AC grid and loading stations. Modular multilevel converter (MMC) holds some remarkable features such as modular design, scalability, reliability, tolerance of failures and larger step up and step down ratio, that make it an essential and meaningful topology for HVDC system. This paper gives an evaluation and assessment over various configurations of higher voltage DC-DC MMCs; it’s working along with characteristic attributes. Furthermore it explains the modulation and control technique considered for DC-DC MMCs.
