Abstract

Effect of ambient conditions on oil impregnated paper insulation is detrimental for an extensive performance of power transformers. In this paper, effect of load, moisture and ambient temperature on the dielectric properties of transformers have been investigated using a multi-regression technique. The proposed technique incorporates the data obtained from several diagnostic tests of transformers. Oil samples collected from different transformers owned by Himachal Pradesh State Electricity Board, India have been tested and analyzed using the proposed method. It has been observed from the analysis that the effect of moisture content on the transformers’ performance is much higher than the effect of load and ambient conditions. The present analysis estimates the oil temperature as per the expected load and ambient temperatures. It facilitates the operating schedule for transformers to improve their service life time.

Abstract

The intelligent controller represents a combined performance of both the Fractional Order PID controller (FOPID) and Cuckoo Search Algorithm (CSA). In this paper, an intelligent controller for the speed control of Switched Reluctance Motor (SRM) drive system using multi-objective function is proposed. The innovation of the proposed method users in enhanced probing skills, ensures the cutback of the irrational arbitrary production and exhibits supreme skills in successfully addressing and adapting the intricate optimization issues. The FOPID is offered carte-blanche in tuning the constraints in view of the fact that the order of derivative and integral do not constitute the integers. It may pave the way for further vibrant accomplishment when compared to the conventional PID controller. Now, the CSA optimized the gain parameters of the controllers for the speed error and current error regulation loops of the SRM drive control mechanism. Further, the proposed control algorithm goes a long way in optimizing the commutation angles for bringing down the lofty torque ripples. Based on the proposed algorithm control parameters, the speed control of the SRM drive has been enhanced. The proposed intelligent control technique will be implemented in the MATLAB/Simulink platform.

Abstract

One of the promising alternative energy sources is the renewable energy sources like wind, solar, etc. Out of the various renewable energy sources, wind energy sector has grown very significantly in India. Generation, utilization and grid penetration of wind energy into the electrical grid is increasing worldwide. As the wind power is fluctuating in nature, it causes stability problems. This paper presents a comparative study on the voltage control capabilities of fixed speed and variable speed induction generators during system disturbance and grid faults. Simulation results show that the DFIG has the capability to control grid voltages and thus is capable of stabilizing the system.

Abstract

Retention of Passenger and Freight Trains working on Electric Traction at Stations in the event of Grid Failures / Locomotive Failures cause inconvenience to passengers and delay in delivery of freight, thereby causing losses in revenue. As Traction is a high Power Application, delivery of Power of the order of 1600 kW per Traction Motor would also cause stresses in the Switching Devices in a 3-j Converter System. In order to overcome stress on Switches, a new Drive System using 5-j Inverter driven Permanent Magnet Synchronous Motor as Traction Motors that can run on both Electric and Diesel-Electric Traction is proposed by the authors in this research paper.

Abstract

The multilevel inverter utilization has been increased since the last decade. These new type of inverters are suitable in various high voltage and high power applications due to their ability to synthesize waveforms with better harmonic spectrum and faithful output. This paper analyzes the Total Harmonic Distortion (THD) performance of a three phase 5- level inverter. The five level inverter is configured with RL load for the analysis. Three different Pulse Width Modulation (PWM) schemes are proposed for the analysis of five level inverter. The simulation results are presented to prove that THD is reduced with different Pulse Width Modulation scheme.
