Design of Active Filter for Reducing Harmonic Distortion in Distribution Network

Power transmission and distribution systems are designed for operation with sinusoidal voltage and current waveform in constant frequency. Power electronic control devices due to their inherent non linearity draw harmonic and reactive power form the supply mains. The wide use power electronic equipment with linear load causes an increasing harmonics distortion in the ac mains currents. Harmonics component is a very serious and harmful problem in the distribution system. The main adverse effects of harmonic current and voltage on power system equipment are overheating, overloading, perturbation of sensitive control and electronic equipment, capacitor failure, communication interferences, process problem, motor vibration, resonances problem and low power factor. This paper describes the modelling of active filter with synchronous d q reference frame theory for harmonic compensation in distribution systems. The case study is carried out at Hlaingtharyar township distribution system. The model is implemented for harmonic analysis from simulation using a Matlab Simulink with the THD values obtained by practical measurement.

Fuzzy Based Algorithm for Cloud Resource Management and Task Scheduling

This paper presents a Fuzzy Logic based approach to manage VM status and VM configuration within the cloud environment. The aim of the approach is to serve task requests efficiently with minimal use of resource and power. The proposed technique uses Fuzzy based approach to calculate the VM's status and VMs configurations, depending upon the cloud resource availability and job resource requirements, and then a fuzzy logic based controller is used to control the status and configurations of the VM to serve the intended purpose afterwards. Controlling in this way reduces the active physical resources and the clouds power requirements. The proposed controller is tested for different load conditions against the standard controlling algorithm to validate the concept. The test results obtained show that in terms of QoS, resource management, and power savings, the proposed fuzzy logic controller based technique outperforms standard techniques.

Speed Control of DC Motor using PID Controller for Industrial Application

This paper is to design PID controller to supervise and control the speed response of the DC motor and MATLAB program is used for industrial application . PID controllers are widely used in a industrial plants because of their simplicity and robustness. The results obtained from simulation are approximately similar to that obtained by practical. Also the dynamic behavior is studied.

Design and Fabrication of Automatic Drain Cleaner

This paper describes about the design and fabrication of automatic drain cleaner. There are a large number of machines used for removing out the wastes from drains. Nowadays, automation plays a vital role in all industrial applications. The automatic drain cleaner can be used in domestic, industry, large plants, irrigation and drainage cleaning system. In order to overcome the problems in manual drain cleaning, Automatic Drain Cleaning System is implemented to clean and control the drainage level. Every automatic drain cleaner has four main components, namely DC motor, 12 V battery, chain drives and shafts. The rotational speed of the drive shaft is 26 rpm. But in this paper, only shaft design is calculated. The required power from a motor to drive this shaft is 60 W. In designing shaft, chain tension, sprocket load and bearing load are taken into account and also bending moment and torque are included.

Simplified Method for Substation Grounding System Design

This paper focused 230 66 kV, substation grounding system and calculation results of required parameters at location of Kalay region. 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. It 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 where the top soil layer resistivity is less than the bottom layer resistivity can be less the number of ground rod used in the grid because the value of Ground Potential Rise GPR is insignificantly different. 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 are designed in detail consideration.

3kw Propeller Turbine Blade Design Based on Tidal Range

Tidal energy is a largely untapped, renewable energy source based on lunar gravitation rather than solar radiation. The generation of electricity from tides is very similar to hydroelectric generation. Tidal energy is clean and not depleting. The tidal schemes may be of single pool or double pool or multi pool. Two types of tidal power plant are barrage style tidal power plant and tidal current power plant. Among them, barrage style tidal power plant was chosen to suit local condition and facilities in Myanmar. Several different turbine configuration are possible. The propeller turbine designed is based on tidal head and flow rate of Kanbalar Creek. The maximum and minimum head of tidal range is 5 m and 2 m. The available flow rate is 0.46 m3 s. The type of turbine is chosen by using 2 m head and 0.46 m3 s flow rate. Therefore, 3 kW propeller turbine is designed in this paper. Then, calculated runner diameter is 280 mm, hub diameter is 112 mm and number of blade is four. Two dimensional blade profile is calculated by using MATLAB program software and drawn Auto CAD software.
