Abstract

In recent years many authors [1-4] are working to obtain single stage HPF electronic ballast for fluorescent and HID lamps to obtain cost reduction and to comply with international standard requirements. Usually to obtain HPF in electronic ballast for high pressure sodium lamps a Power Factor Preregulator (PFP) is used between the mains and the electronic ballast. In this paper will be reported the study and implementation of two single stage High Power Factor (HPF) electronic ballasts for high pressure sodium (HPS) lamps using a LCC filter, one using a half-bridge inverter and the second one using a full-bridge inverter. The main idea in this work is to compare two simple electronic ballasts topologies with HPF for HPS lamps working with a 220 VRMS mains voltage. Design criteria, simulation and experimental results will be also presented for a full bridge inverter in the final paper.

Abstract

The Unified Power Flow Controller (UPFC) is one of the key Flexible AC Transmission System (FACTS) controller used to control active and reactive power flow in a transmission line and regulate the bus voltage within specified limits at which UPFC is connected. The Proportional and Integral (PI) controller of UPFC is not enough to damp power oscillations because of slow response of PI controller. This paper presents Fuzzy Logic Power Oscillation Damping (FLPOD) controller along with PI controller to improve the performance of UPFC in damping of power oscillations. The UPFC with the proposed controller effectively damps power oscillations after clearing fault in the power system. The UPFC with proposed controller is tested on Western System Coordinating Council (WSCC) — 9 Bus system through simulation by using SIMULINK.

Abstract

This paper presents accurate calculation of apparent impedance of transmission lines by distance protection scheme.The apparent impedance equation, considering the transmission line capacitance by utilizing a double p model for a line is derived. The apparent impedance without and with considering the line capacitance is compared by considering the fault resistance. The quadrilateral characteristic of distance relay is compared in both the cases. Simulink model design and adaptive setting for a distance protection with consideration of transmission line capacitance is also investigated using Fourier transform. A 400 kV transmission line with 300km long is used in this study.

Abstract

The analysis of Automatic Generation Control (AGC) of a two area interconnected power system considering Static Synchronous Series Compensator (SSSC) in series with the tie-line is presented. This paper proposes a new application of one of the sophisticated FACTS (Flexible AC Transmission Systems) devices, i.e. Static Synchronous Series Compensator (SSSC) to stabilize the frequency of oscillations in an interconnected power system. The SSSC located in series with the tie line between any interconnected areas is applicable to stabilize the area frequency of oscillations by high-speed control of tie-line power through the interconnection. The mathematical model of SSSC is derived from its characteristics of power flow control. The idea based on a dynamic control of tie-line power is applied to stabilize the frequency oscillations of inter area mode. Simulation study exhibits the significant effects of the proposed control.

Abstract

The HVDC transmission system is becoming ever more complex, further, demand for reliable supply of electricity is growing, increasing the need for a higher level of system reliability. A probable solution might be to incorporate controllable power components within the system. One such important is smoothing reactor or DC reactor. In this paper the effect of failure rate and repair time on expected capacity level or power transmission capacity of smoothing reactor at different inductance values with one, two and without spares is analyzed and compared. And also effect of number of spares on expected capacity level is presented.
