DESIGN AND IMPLEMENTATION OF AUTOMATIC CHANGE OVER USING PLCMohamed Riyasudeen
Power failure or Power outage is the main issue regarding the
continuity of supply to be maintained like in industries and factories with
constant power failure are not efficient. The supply of electricity for
industrial, commercial and domestic use is highly unstable. This gives rise
to the frequent use of alternative sources of power supply to meet up with
the energy demands. The introduction of these alternative sources of
supply brings forth the challenge of switching smoothly and timely
between the mains supply and the alternative sources whenever there is a
failure on the mains source.
The changeover system mainly reduces the problem regarding
manual switching. This paper can be represented by the construction and
design of PLC based auto-changeover system. The main aim of this project
is to supply uninterruptable power to the Industries, Hospitals, Education
Centres, etc.., by automatic change over control system through PLC

Internet of Things is a concept where each device is assign to an IP address and through that IP address anyone makes that device identifiable on internet. Basically it started as the “Internet of Computers.” Research studies have forecast an explosive growth in the number of “things” or devices that will be connected to the Internet. The resulting network is called the “Internet of Things” (IoT) [1]. The recent developments in technology which permit the use of Bluetooth and Wi-Fi have enabled different devices to have capabilities of connecting with each other. Using a WIFI shield to act as a Micro web server for the Arduino which eliminates the need for wired connections between the Arduino board and computer which reduces cost and enables it to work as a standalone device. The Wi-Fi shield needs connection to the internet from a wireless router or wireless hotspot and this would act as the gateway for the Arduino to communicate with the internet. With this in mind, an internet based home automation system for remote control of home appliances is designed.

FOUR QUADRANT SPEED CONTROL OF DC MOTOR USING AT89S52 MICROCONTROLLERJournal For Research
Speed control of a machine is the most vital and important part in any industrial organization. This paper is designed to develop a four quadrant speed control system for a DC motor using microcontroller. The motor is operated in four quadrants i.e. clockwise, counter clock-wise, forward brake and reverse brake. It also has a feature of speed control. The four quadrant operation of the dc motor is best suited for industries where motors are used and as per requirement they can rotate in clockwise, counter-clockwise and also apply brakes immediately in both the directions. In case of a specific operation in industrial environment, the motor needs to be stopped immediately. In such scenario, this proposed system is very apt as forward brake and reverse brake are its integral features. Instantaneous brake in both the directions happens as a result of applying a reverse voltage across the running motor for a brief period and the speed control of the motor can be achieved with the PWM pulses generated by the microcontroller. The microcontroller used in this project is from 8051 family. Push buttons are provided for the operation of the motor which are interfaced to the microcontroller that provides an input signal to it and controls the speed of the motor through a motor driver IC. The speed and direction of DC motor has been observed on digital CRO. Microcontroller programming has been written in assembly language by using notepad and it has been converted in hex file by using micro vision Kiel. The burning of programming in the 8051 microcontroller chip has been done by using positron boot loader software.

High Speed SRM Using Vector Control for Electric VehicleAsoka Technologies
The high speed motor is effective to realize downsizing motor in an electric vehicle (EV). Switched Reluctance Motor (SRM) is possible to the high speed drive because the rotor structure has simple and robust. However, the vibration and the acoustic noise are large from the drive principle. Moreover, the conventional complicated current excitation results in the difficulty of the torque controller design. To overcome these problems, the vector control has been proposed for SRM drive. However, the vector control has not been applied to the SRM in the high speed drive. In this paper, the drive conditions such as switching frequency, bus voltage for driving the SRM in the high speed region are clarified. It is shown that the proposed SRM can be driven by the vector control in the high speed region and can realize low vibration.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
