The paper presents a method for estimating the continuity in supplying electric power systems based on building probability density function bivariate Gram-Charlier. Previously is used the same approximation for the probability distribution function for all load flows branches convergent to systems nodes considering the units generators outages and branch(More)
4 This paper presents a software tool for a three-phase voltage dip signal generator, which can be used to generate waveforms similar to those recorded. The voltage dip signal generator is designed to shape the voltage waveforms for the three phases, using random functions for almost all possible parameters. The advantage of using the generated waveforms(More)
Voltage dips are one of the most important power quality problems. The major disadvantage in studying this phenomenon is the difficulty to obtain the necessary data. This disadvantage is to the fact that the phenomenon is random and monitoring must be carried out for long periods of time. In these conditions the paper proposes a three-phase voltage dips(More)
AC overhead lines through their constructive asymmetry causes significant unbalance of currents and asymmetry of voltages on the three phases of the network. These unbalances of the operating conditions are even higher as the lines has greater lengths and the transported powers are higher and is therefore primarily characteristic for the transmission lines.(More)
The paper presents a fuzzy approach for harmonic voltage level based on the linguistic prescription of power quality standard. Harmonic currents are mainly generated by industrial and residential loads with non-linear characteristics. Industrial loads which are a source of significant levels of harmonic distortion include power converters, variable speed(More)
The main focus of this paper is to presents comparative principal problems of bibliographies on the linearization of Load Flow equations, network outages and the interdependence among nodal power injections. These methods classified as simulation method, analytical method, or by a combination of both are used to obtain the mean and variance of Power Line(More)
Capacitive shunt compensation of a three phase power distribution network is usually done to improve the voltage level in the network buses and / or to reduce the active power losses. Most often this compensation could be made also for network load balancing, which will also have a positive effect on voltage quality. For this, a shunt unbalance capacitive(More)
