Voltage Stability Analysis under Normal and Contingency Conditions Mini Projects EEE Power Systems

Introduction to Voltage Stability Analysis under Normal and Contingency Conditions:

The project aims at designing a voltage stability analyzer which can work effectively under normal and contingency conditions. In this we will design a algorithm so as to calculate the voltage fluctuation occurring and maintain a constant supply voltage. In this paper we will discuss the about the algorithm for calculating the voltage fluctuations occurring in the device.

Brief into the working of voltage stability analyzer:

Due to small disturbances occurring in the device the system may collapse, so to control these we will design a algorithm. In this we will use an L-index method for calculating the voltage fluctuation values. By suing the L index method we will obtain scalar values of the load elements used in the circuit.

By maintaining the L index values at 0 to 1 margin the voltage fluctuations are controlled. By using this we can know the load elements values so that we can know the disturbances occurred due to load elements. The software for analyzing the voltage values is designed using mat lab program.

The application software predicts the change in voltage values and maintains a constant phase margin. This is a cost effective system for controlling the voltage fluctuations in electrical devices.

Applications:

By using this device we can control the voltage fluctuations occurring in a device. As we can know the voltage values by using the stabilizer we can adjust the voltage values according to our requirement. By using this device we protect the device from damages occurring due to over voltages and short circuits. The voltage stability analyzer can work efficiently in both low voltage and high voltage conditions.

Ultra High Speed Low Power Electric Drive System Project Report

Introduction to electric drive systems:

Small and portable power compressors and spindles require ultra high speed and low power electric drives. In this paper we will discuss a drive system which operates at 500000 rpm and output power of 100w. The proposed design has a bidirectional power capability and drive controller. This drive system can be directly connected to mesoscale gas turbines.

Drive system overview and design:

To design such high speed and low power portable models, machine and power electronics are to be considered together other one factor may influence the other factor. Depending upon the size of the design the torque and speed varies. Micro gas turbine systems have an direct connected permanent magnets which generate output power in the range of 10 to 100 watts. The power electronics allow the ac currents of the machine in a bidirectional power flow. A dsp processor is used to implement a drive control system which allows the drive to communicate with the other control systems. For gate drivers dsp and other control drives an additional auxiliary power supply is provided. The drive control is designed by using a position sensor and is monitored in software platform. To achieve the speed of 500000 rpm high speed ball bearings are used and which are of small size and have high robustness. Static air bearings or dynamic air bearings are used to generate air pressure in the rotor and these have very low fiction and a long life time.

Power electronics selection and operation:

The power electronics interface becomes very complex for the drives with low motor inductance of small designs with high fundamental frequency. For such selection the machine design and the number of passive components and position of rotor and speed sensing factors are to be considered. For such drives sensor less position estimation is the best approach because of space restrictions. Synchronous position motor gives the rotor position information so that we can provide proper communication to the phase currents. Thus we can conclude that such small drives are designed by undergoing various complexities.

Speed Control of DC Motor Using Fuzzy Logic Controller EEE Project

The main of this project is to control speed of the D.C motor using the fuzzy logic control, By using the MATLAB software and compare the response with the proportional, proportional integral and proportional integral derivative controllers. Fuzzy logic control is the MATLAB operation programming, so to implement this EEE project we have to use the MATLAB software. This topic describes the dc motor model (mathematical and Simulink), controller types, responses of proportional, proportional integral and proportional integral derivative. In proportional integral derivatives we have to solve the derivatives, and Fuzzy logic controlling system. To implement this project we have to now the concepts of motor model, driver circuit, fuzzy logic controller design, process blocks of the fuzzy logic controller, and the membership rules.

Fuzzy Logic Controller features and advantages:

The fuzzy logic controller is sensitive to variation of the speed of the attenuation, the gain should be minimum and the fuzzy logic controller can control the D.C motor speed. The D.C motor consist of volt meter to set the voltage, armature, load, multiplier for the back E.M.F. the products used in the project are very costly so to avoid the problem of damaging the resisters and inductors and motor parts the heat should be minimum. Specifications of the motor are motor type 5HP,  Rated armature voltage 500volts, rated speed 1500rpm, Ra(armature resistance)=11.2Ω, La(armature inductance)=0.12h, EMF constant k=1.28N-m/A.
