This paper presents the design and analysis of a cost effective power quality improvement method using de-tuned filters for an electric power distribution network. Analysis of the resonance at different harmonic components such as 5, 7, 11 and 13, as well as power factor (PF) improvement has been carried out by a capacitor bank. By connecting a capacitor bank will produces harmonics amplification,...
The power quality disturbances are still unsolved problems due to the increased power electronic load getting into the system. This is as a result of continuous use of non-linear loads and the faults that occur on the power system. The power quality disturbances that often occur include voltage sag, voltage swell, harmonics, transients, flicker and interruption. To detect power quality disturbances,...
Power transmission is one of the fields drastically growing in the world presently. In this paper, it is aimed to provide a solution for detecting the fault and its location accurately by utilizing ISFHA-[Improved Sheep Flock Heredity Algorithm]. It is necessary to satisfy the customer in terms of power quality transmission. Power quality damages occur due to short circuit, natural disasters and other...
Overhead lines dominate the planet much more than underground cable system primarily because of its lower cost of transmission (as low as 10 % of underground transmission). Disc insulators form a critical component in isolating the line conductors from tower structures both in EHVAC and HVDC transmission lines. Over the years, many types of materials are chosen for use in the transmission lines right...
The introduction of flexible AC transmission system (FACTS) in a power system improves the stability, reduces the losses, reduces the cost of generation and also improves the loadability of the system. In the proposed work, a traditional technique is used to analysis its stability, Equal Area Criterion (EAC) is used to analysis the stability with and without introducing of TCSC devices in a power...
A substantial increase of photovoltaic (PV) power generators installations has taken place in recent years, due to the increasing efficiency of solar cells as well as the improvements of manufacturing technology of solar panels. These generators are both grid-connected and stand-alone applications. The paper concentrates on the operation and modeling of stand-alone power systems with PV power generators,...
A soft switching implementation without additional device, high efficiency, simple control zero voltage switching (ZVS) bidirectional isolated DC-DC converter is presented in this paper. This is used in high power application especially for power supply in fuel cell vehicles electric vehicle driving system and power generation where a high power density is required. This technique has the advantages...
