the interline power flow controller (ipfc) is a concept of the facts controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. this paper proposes a novel ipfc-based damping neuro-control scheme using pso for damping oscil la t i o ns in a power system to improve power system stability. the add i tion of a supplementary controll...

Among Generation, Transmission and Distribution systems of power 80-90 % faults occur in transmission lines. A small electricity interruption or disturbances can cause major problems Major lines because environmental events like high temperatures, animals, wind, etc also faulty devices connected to are a for these faults. In modern line one the significant leading losses electrical failure. So,...

Protective relays are installed in generation, transmission, and distribution system for detection, classification, estimation of faults. To match the future load demand to get uninterrupted power supply, use renewable energy sources increasing day by day. Faults can occur transmission lines, transformers, generators, busbars but nature these faults may change many times when considered. This r...

This paper presents an approach for the maximal diagnosis of all faults (stuck-at, open and short) in the interconnect of a random access memory (RAM); and the interconnect includes data and address lines. This approach accomplishes maximal diagnosis under a complex model in which the lines in the interconnect of the RAM can be affected by multiple faults. Maximal diagnosis consists of detectio...

1 INTRODUCTION Electric power utilities have sustained significant damage from lightning. The occurrence of line faults is one result of lightning damage. To prevent it, power utilities adopt various measures of protection from lightning. Transmission line overhead ground wires greatly contribute to a decrease in the number of line faults by preventing direct hits to the power lines. Lightning ...

Abstract This paper presents wavelet based analysis for transmission line fault location. Faults in power transmission lines cause transients that travel at a speed close to the speed of light and propagate along the line as traveling waves (TWs). Traveling wave theory is utilized in capturing the travel time of the transients along the monitored lines between the fault point and the protective...

Voltage clamps for protecting low-voltage dc circuits require a new approach to circuit design. Many commonly used voltage clamps were built for systems of 5 V or higher, but lower-voltage systems require distinctive clamping abilities. The use of very-low-voltage precision enhancement-mode MOSFETs play a pivotal role in designing voltage clamps in low-voltage applications. Today’s electronic s...

Power transformers are important and expensive components in the electric power system. The knowledge of the actual status of the transformer insulation behavior, load tap changer performance, temperature, and load condition is necessary in order to evaluate the service performance concerning reliability, availability and safety. Systems abnormalities, loading, switching and ambient condition n...
