Monitoring Station based on Virtual Instrumentation applied to a Distillation Column

Abstract: This paper presents the design and the online implementation of a monitoring station for a distillation column. The purpose of the monitoring station is to supervise and ensure the quality of the distilled product, through the analysis of the process operation, which can reduce production costs. The monitoring station is designed for a distillation column pilot plant in a batch-type operation mode, it is based on temperature measurements. It has 7 Pt-100 RTD temperature sensors, located in the boiler, the condenser and in 5 plates of the column body.

Life cycle cost applied to grid code compliance in load centers in Mexico

Abstract: With the currently grid code applied to load centers in Mexico, an special attention is taking care on power quality solutions, mainly for power factor correction, reduction of total harmonic distortion of demand and current imbalance. It is desire that all the technical solutions for these power quality problems includes life cycle cost analysis in order to obtain the best economical solution. In this paper an analysis is presented, showing a technical solution for harmonic distortions, power factor and impacts in the reliability of equipment, complemented with the analysis of life cycle costs of an asset, thus obtaining criteria to select the better system that maximizes the profitability of a process in a plant under a cost-risk-benefit approach.

Power Flow Solution in Direct Current Power Systems

Abstract: Load flow formulations for direct current almost always are considered into the framework of integrated Alternating Current/Direct Current (AC/DC) power systems, but generally these formulations do not include the presence of loads and multiple generators in the DC power system. In this paper, the power flow problem for DC power systems is formulated and solved. The resulting nonlinear equations are solved by the Newton Raphson Method. Also, it is discussed the inclusion of several controlled voltage nodes and their treatment is described. The developed algorithm has been proven through an illustrative example with a five-node power system. Finally, concluding remarks of the algorithm developed are pointed out, and future work in this field is suggested.

Water electrolysis experimental characterization and numerical model: Case of study with three kind of electrodes

Abstract: Hydrogen is considered as a reliable energy storage medium for sustainable and renewable energy systems in the future. The production of hydrogen by alkaline electrolysis of water consists of the application of an electric potential that allows separating the H 2 O in molecular gaseous hydrogen and oxygen particles. Thus, in order to develop more suitable systems the use of models based in the finite element method has been recently explored. However, no especial attention has been paid in the selection of the electrode's material. In this work, a finite element model was developed based in the current distribution theory and Nernst and Butler-Volmer equations. The model and experiments consider three types of electrodes. Finally, the model results and experimental data were compared to observe a disturbing behavior in the equilibrium potencial, this could be attributed to a low reduction potencial in electrode's components.

Modeling of magnetic levitation systems using finite elements and an analytical solution

Abstract: The Magnetic Levitation systems (MagLev) have important applications such as: levitation of superconductor materials, high speed transport, power interrupters (used as actuators) and elimination of electric arcs. Therefore, numerical and analytical modeling of MagLev is important. The aim of this work is to obtain the dynamic model of the MagLev with a simple electrical and magnetic treatment. The analytical solution thus obtained is valid for any system with the same characteristics. The Finite Element Method (FEM) is then used to extract mutual inductance. Finally, a comparison of simulations results against experimental ones, is performed.
