Load profile estimation in points of consumption, distribution transformers and feeders in distributions systemsEstimación de curvas de demanda de consumidores, transformadores de distribución y alimentadores primarios en sistemas de distribución
(Pereira : Universidad Tecnológica de Pereira, 2007)
Este artículo presenta una metodología para la estimación de curvas de demanda de potencia diaria a nivel de consumidor, transformador y alimentador primario. La estimación de las curvas toma como referencia mediciones de ...
Geometric Parameterization Technique for Continuation Power Flow Based on Quadratic Curve
(2017-10-21)
The electricity sector, especially in emerging countries, has experienced several transformations, mainly resulting from the increase of electricity demand. This encourages more investment in the generation sector and ...
Obtaining the Maximum Loading Point of Electric Power Systems using the Decoupled Methods of Newton
(Ieee-inst Electrical Electronics Engineers Inc, 2016-01-01)
This paper presents a proposed Newton decoupled method modification (simultaneous resolution algorithm and alternate) with the addition of an equation line passing through of a point in the plane determined by the variables: ...
Characteristics of the double-torsion test to determine the R-curve of ceramic materials
(2006-10-01)
Double-torsion tests were carried out on a commercial ceramic floor tile to verify whether this test is suitable for determining the R-curve of ceramics. The instantaneous crack length was obtained by means of compliance ...
Non linear fracture mechanics of polymers: Load Separation and Normalization methods
(Pergamon-Elsevier Science Ltd, 2012-01)
Fracture toughness of ductile polymers can be measured by the incremental crack growth resistance curve, where J-Integral value is plotted as a function of crack extension. The determination of the resistance curve, J-R, ...
A Top-Down Approach for Distribution Loss Evaluation
(Institute of Electrical and Electronics Engineers (IEEE), 2009-10-01)
A methodology, which can be classified as Top-Down, aimed at computing technical losses in distribution systems is proposed. It can be applied to either evaluate part of the network or to analyze the whole distribution ...
Effects of specimen geometry and loading mode on crack growth resistance curves of a high-strength pipeline girth weld
(London, 2014-02-11)
This work presents an investigation of the ductile tearing properties for a girth weld made of an API 5L X80 pipeline steel using experimentally measured crack growth resistance curves. Use of these materials is motivated ...
Dishonest Newton Method Applied in Continuation Power Flow Through a Geometric Parameterization Technique
(2016-01-01)
The electricity sector has gone through several transformations due primarily to increased electricity demand, especially in emerging countries. This encourages more investment in the generation and leads to a growing ...
Study of alternative schemes for the parameterization step of the continuation power flow method based on physical parameters, part II: Performance evaluation
(Taylor & Francis Inc, 2003-12-01)
New parameterization schemes have been proposed by the authors in Part I of this paper. In this part these new options for the parameterization of power flow equations are tested, namely, the total power losses (real and ...
The cone loading test to estimate deformability moduli of a tropical soil
(2013)
The Cone Loading Test (CLT) consists of the execution of a load test on the piezocone probe in conjunction with the CPT test. The CLT yields the modulus ECLT, a parameter that can be used in the estimative of foundation ...
