This paper presents a detailed analysis of commutation failure, AC/DC power flow, and voltage stability multi-infeed high-voltage direct current (HVDC). The use HVDC transmission technology has become common in modern systems. During the past two decades, been extensively used for long-distance bulk to remote areas. Throughout world, demand drastically increased recent years due industrializati...

The electrical energy supply of industrial equipment is provided by power stations with high- (HT), medium- (MV) and low-voltage (LV) busbars. Consumers are connected to either MV or LV In this paper, a real station was considered, through which the gasoline extraction from well gas installation powered. Electric consumers (electric motors) supplied busbar have active 13.54 MW, those fed 6.4 MW...

The electrical power system is susceptible to several faults, which can cause the malfunction. Among these, ones that occur in busbars of substations stand out. main bus a substation concentrate large amount and many derivations service loads, making it an element high importance for reliability system. Although buses have low incidence they are considered critical elements system, as their ope...

The reliable performance of the shipboard power system (SPS) is essential for safe and efficient operation marine vessels. SPSs are subject to various types electrical faults that can cause equipment failure, downtime, even catastrophic events. One effective way provide redundancy fault tolerance in event a or failure through use zonal configuration. However, protection such systems challenging...

This article presents a complete plasma etching process to etch high aspect ratio patterns on III-V/Ge solar cell heterostructure with low damage for the fabrication of multijunction cells through via contact architecture. A SiCl4/H2 chemistry was studied different hydrogen dilutions within (0%, up 67%) and cathode temperatures (20∘C, 200∘C). choice creates SiClx-based inhibiting layer sidewall...

Coordination of a power system with the phasor measurement devices (PMUs) in real time on load and generation sides is carried out within context smart grid studies. Power systems equipped information pace external security threats. Developing which can resist against cyber threats considered indispensable for uninterrupted operation. In this study, two-way secure communication methodology unde...

Single-ended protection systems present the characteristics needed to fulfil restrictive speed requirement related high voltage direct current grids. This paper proposes a novel single-ended algorithm based on DC across limiting inductors placed at each link end. Voltage measurements are taken both terminals of inductors. The ratio between link- and bus-side voltages enables fault discriminatio...

Photovoltaic (PV) systems are becoming increasingly prevalent worldwide, particularly in power distribution networks. However, their intermittency and integration into networks can have adverse effects. This study investigates the impact of large-scale solar a typical Malaysian grid network, focusing on voltage stability, short circuits, loss under peak no-load conditions. Using Digsilent Power...

This study attempts to optimize the arc-shaped coned disk affecting uniformity of earlier designed fertilizer apparatus (FA), in particular, for application rice–oil rotation region middle and lower reaches Yangtze River, China. Based on theoretical analysis, a circular with curvature gradual decline (GD) from top bottom was designed, equation cone determined. The EDEM discrete element software...

The use of renewable energy such as photovoltaic is growing. According to IRENA, these systems are one the most dynamic generation technologies. global market has grown rapidly between 2000 and 2016 at an annual average compound rate 44%, from 0.8 GW 291 GW. In Colombia, regions with high solar irradiation levels have been identified emerging markets. Government's plan increase share non-conven...
