Speed Control System for BLDC Motor by using Direct Back EMF Detection Mathod

BLDC motors are used in many industrial and traction applications due to high efficiency, low maintenance and high torque. For good performance of BLDC motors, the accurate knowledge of the rotor position is required. The need for the rotor position information in BLDC motors have been satisfied by use of some form of rotor position sensors. But to reduce cost, complexity and also to improve reliability of the system, sensor less drive system is preferred. In this paper, the development of sensor less control system for BLDC motor using a direct back EMF detection method is presented and simulation for proposed system is done with the help of MATLAB SIMULINK.

Design and Simulation of Automated Packaging Machine Process Control by Using PLC

Industry automation becomes the global trend in manufacturing and packaging process is one of the uses in industry. Modern industrial plants require the automatic process control system to control the desired process. The programmable logic controller PLC is very useful for the industrial automation in the modern business world. Industrial automation plays an important role in increasing the yield of a product. And then, among the controlling systems, the PLC control system has more applications than the other numerical control systems. It can be observed that a circuit has a fault by checking the control panel board. Troubleshooting can be done quickly visual observation. The main idea of the paper is to automate the process for packaging the detergent that weights 85 kg. Programmable logic controller SIEMENS SIMATIC S7 300 CPU 214C 2PN DP AC DC relay was used to control and automate this machine by ladder logic diagram software. In this paper, TIA portal V 13 software is used as programming software.

Design of Grounding System for Substation

This paper presents 230 66 kV, substation grounding system and calculation results of required parameters. The grounding system is essential to protect people working or walking in the vicinity of earthed facilities and equipments against the danger of electric shock. This paper provides the floor surface either assures an effective insulation from earth potential or effectively equipment to a close mesh grid. Calculations of grounding grid system in the substation area which the top soil layer resistivity is less than the bottom layer resistivity, can lessen the number of ground rod used in the grid because the value of Ground Potential Rise GPR is insignificantly different. Essential equations are used in the design of grounding system to get desired parameters such as touch and step voltage criteria for safety, earth resistance, grid resistance, maximum grid current, minimum conductor size and electrode size, maximum fault current level and resistivity of soil. Calculations of three separate earthing body earth, neutral earth and main earthing are described.

Design and Implementation of Electronic Payment Gateway for Secure Online Payment System

In e commerce, main problem is to be more secure for payment systems and disputation between online merchant and customer. To solve this problem, this paper presents design and implementation of Electronics Payment Gateway for online payment system. In this system, a customer's financial information credit or debit card information is sent directly to a Payment Gateway also called Trusted Third Party, TTP instead of sending it through an online merchant. The Payment Gateway can support more secure for online payment system. In this system, Secure Socket Layer SSL with Rivest Shamir Adleman RSA is used to enhance more secure connection in payment process. In secure online payment system, end to end encryption is required to maintain the integrity of transactions carried out online. RSA is more secure because its factors are large integers and key size is large, which increases the security. The electronic payment gateway provides the confidentiality by using RSA for online payment transactions and trusted third party to recover the disputation between online merchant and customer.

Performance Analysis of Autonomous Hybrid Distributed Generation Based on Typical Control Strategies for Rural Electrification in Myanmar

It is undeniable fact that even though fossil fuels are likely more to fulfill the requirements of energy, the rare of natural resources and their harmful contents for the environment have directed people to search for new energy sources like renewable resources such as hydro power, biomass, wind, solar and other types of clean energy. In order to highlight the proposed methodology, PV Diesel generator DG with battery energy system BESS based on two typical control strategies, load following LF control strategy and cycle charging CC control strategy, have been analyzed by using HOMER Software to supply the Makyiyay village which is located at 22.02 north latitude and 96.56 east longitude in the Naungkhyo Township, Southern Shan State in Myanmar. The yearly average solar radiation of that area is 4.895kWh m2 day and it is very important to prepare a proper load data to meet the current situation of the target village which has 45 household numbers. By calculating the total load demand, the peak demand of that proposed village is 34kW. The fractions of energy production from PV array and diesel generator of the proposed PV Diesel BESS hybrid system using LF control strategy are 60 and 40 to meet the demand. Moreover, the proposed hybrid system based on LF control strategy provides the lowest TNPC, COE and carbon emission than the hybrid system based on CC control strategy according to the evaluation results. In contrast, the analysis of evaluation results shows that the PV Diesel ESS based on LF control choice is more economically possible than that system based on CC control.

Performance Analysis between H.323 and SIP over VoIP

There are a number of protocols that may be employed in order to provide the Voice over IP VoIP communication services. In VoIP system, H.323 and Session Initiation Protocol SIP are the two major standards. Both of these signaling protocols provide mechanisms for multimedia teleconferencing services. Although the two protocols architecture is quite similar, they have many differences. This system presents Voice Video over IP communication and summarizes the differences and performance of two major VoIP protocols, H.323 and SIP according to the packet delay variation, jitter, packet loss, and Packet end to end delay. It is found that both of them are non interoperable, approaching each other, their focus and applicability is still different. In this paper, the system is designed and configured by Graphical Network Simulator GNS3 and analyzed performance by Opnet Modeler Simulation.

Strength of Concrete Structure Partial Replacement of Sand by Copper Slag

The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix and time and quality of the curing, the compressive strength of concrete can be obtained up to 95 MPa or more. Commercial production of concrete with ordinarily aggregate is usually in the 20 to 80 MPa range with the most common ranges for cast in place buildings from 20 to 40 Mpa. On the other hand, precast and pre stressed applications often expect the strengths of 25 55 MPa. Although concrete is not normally designed to resist direct tension, the knowledge of tensile strength is used to estimate the load under which cracking will develop. This is imputable to its influence on the formation of cracks and its propagation to the tension side of the reinforced concrete flexural member. Shear, torsion, and other actions also produce tensile stresses to the particular section of concrete members. In most cases, member behavior changes upon cracking. So the tension strength of concrete is also considered in the proportioning concrete member. This strength is of interest in designing of highway and airfield slabs as shear strength and resistance to cracking are very important to sustain such loading. The tensile strength of concrete is relatively low, about 10 to 15 of the compressive, occasionally 20.
