This paper proposes a numerical method to calculate the induced potential and current in pipelines installed near a horizontal grounding electrode subjected to lightning discharge using the transmission line approach. The effect of this induced potential on the pipeline metal corrosion has been highlighted in term of mass loss for different soil resistivities and separation distances between pipeline...
This investigation is devoted to study the transient behavior of long horizontal grounding conductor submitted to high impulse current using Transmission Line Method (TLM) incorporating soil ionization and/or mutual coupling phenomena. As results, soil ionization generates a very slight decrease in potential values. This diminution is accentuated when considering mutual coupling phenomenon. A good...
This paper aims to study the transient behavior of vertical grounding electrode under impulse current and buried in homogeneous soil. We have interested to the variation of the grounding impedance as function of frequency as well as the evolution of the transient potential using Transmission Line Method (TLM) in domain time. Several current magnitudes and soil resistivities and permittivities have...
This paper deals with the use of the transmission line approach to analyse the transient behaviour of isolated and interconnected grounding systems of wind turbines under lightning discharge. The effects of the soil resistivity as well as the grounding systems interconnection type (cascade and closed) have been studied. As main results, the interconnection leads to a decrease of the impedance and...
This paper is intended to solve the optimal power flow (OPF) dispatch in the presence of wind power generation (WPG) in the Adrar power system. Towards this aim, the performances of three powerful meta-heuristic algorithms-namely, the cuckoo search algorithm (CSA), firefly algorithm (FFA), and flower pollination algorithm (FPA) are investigated. The proposed algorithms are applied to best capture...
In this paper, three metaheuristic techniques have been developed to propose a safe and economic grounding system for the future power plant of Labreg situated in Khenchela City (400 km east of Algiers). The corresponding algorithms have been elaborated using particle swarm optimization (PSO), genetic algorithm optimization (GAO) and hybrid particle swarm genetic algorithm optimization (HPSGAO). The...
This paper proposes a new hybrid particle swarm optimization with gravitational search algorithm to solve the economic/environment optimal power flow dispatching incorporating wind power generations into the isolated Adrar Algerian power system. Taking into account the intermittent of the wind speed, the maximum probable active wind power generation is estimated by computing the wind speed carried...
