Present paper studies the current harmonic spectrum generated by functioning of an electrothermal installation with electromagnetic induction. In order to analyze the electrical parameters that characterize the electrothermal installation functioning, measurement sets were accomplished using two methods. The first method consists in using a power and energy quality analyzer and the second metho...

Wind energy has huge potential to become major source of renewable energy for the modern world. For integrating wind farms to the AC grid, HVDC transmission systems have several advantages over AC transmission systems. This paper presents the design and control of voltage source converter based HVDC system for integration of wind farms in to AC grid. The designed VSC-HVDC system performance und...

In this paper, a wind turbine simulator is developed using PSCAD. The wind turbine static characteristics are modeled using the relation among the turbine power, the wind speed, and the blade pitch angle. Also, the dynamic characteristics of the wind turbine are modeled through a two-mass oscillating system, representing the turbine and the generator connected by elastic shaft. The system consi...

In this paper, new voltage sensitivity indexes are proposed to search and evaluate the candidate buses in a microgrid, where the energy storage systems can be installed to contribute most effectively to the system. These indexes are derived from the inverse Jacobian matrix from the NewtonRaphson power flow analysis. After calculating and evaluating these indexes for the studied microgrid, four ...

This paper present the results obtained by simulation for the functioning regime improvement of an UHP Electric Arc Furnace. Because the nonlinearity of the electric arc the EAF functioning regime are perturbed from three causes: the current harmonics, the reactive power and the unbalanced load. In this paper there are study the possibilities of harmonics filtering and compensate the reactive p...

In this paper, impedance based method and matching approaches were used separately to detect three phase to ground fault (LLLGF). In order to observe the accuracy of each method, Non-homogeneous distribution network was used as a tested network. Actual data from TNB (Tenaga National Berhad) Malaysia was adopted to model the network by using PSCAD/EMTDC simulation program. Both methods were test...
