-This paper presents a steady-state model of a gridconnected photovoltaic (PV) system using Electromagnetic Transient Program (EMTP) MODELS. Recently the PV system has been introduced in power systems. The previous PV generation was used only to supply small loads or for home use. Nowadays, installations of grid-connected PV systems are increasing due to several advantages compared to standalon...

High-speed auto-reclosing is used in power system protection schemes to ensure the stability and reliability of the transmission system; leader-follower auto-reclosing is one scheme type that is widely used. However, when a leader-follower reclosing scheme responds to a permanent fault that affects a transmission line in the proximity of a generation plant, the reclosing directly impacts the tu...

The paper presents a general procedure for the evaluation of the indirect lightning performance of a distribution network, which takes into account the actual network topology and the presence of transformers, surge arresters and line poles. The procedure is an extension of a Monte Carlo-based approach developed for a single straight overhead line to the case of a more complex distribution netw...

The emerging theory of compressive sensing CS provides a new sparse signal processing paradigm for reconstructing sparse signals from the undersampled linear measurements. Recently, numerous algorithms have been developed to solve convex optimization problems for CS sparse signal recovery. However, in some certain circumstances, greedy algorithms exhibit superior performance than convex methods...

Abstract In order to limit the temporary overvoltage, method of series current limiting reactor in line is often used power grid overvoltage. The parameters reactance directly affect level 50Hz installation a changes positive and zero sequence impedance line, which has an impact on overvoltage line. Installing 500 kV Line’s studied by using electromagnetic transient calculation software EMTP. s...

In order to improve the power quality maintenance and reliability of power supply, different types of faults on the transmission line namely: open-circuit (OC), short-circuit (SC), high impedance faults (HIF) and the fault caused by direct lightning strike (LS) have been investigated in this paper. The disturbances have been modelled and simulated using a well-known transient simulation tool Al...
