Adicionalmente, se midió la energía generada e inyectada a la red interna, como así también el Nivel de Tensión en la barra. En este Trabajo se presenta un análisis completo de las mediciones efectuadas, evaluando el contenido armónico según la hora del día y por lo tanto conforme a la energía generada por los paneles. Se presta particular atención, además, al tipo de día que se trate (laborable o no laborable), dado que esto afecta directamente al consumo global del edificio. Finalmente, se concluye si la inclusión del generador fotovoltaico tiene - o no - un impacto directo sobre el establecimiento, en materia de Calidad de Servicio Eléctrico.; In order to assess the effect of the PV-Generator on the preexisting LV network, normalized measurements of harmonic content were performed. Such measurements were performed at the point of coupling between the generator – and the corresponding converters – and the internal LV network. In addition, the energy generated and injected to the LV network as well as the Voltage Magnitude in the internal bar were also measured. In the article a complete analysis of the measurement results is presented. The harmonic content is assessed according to the hour of the day, and consequently the energy generated by the PV panels. Added to this, we analyze the harmonic content distinguishing between working days and weekends, since the global consumption of the building depends on the type of day. Finally, it is concluded whether the inclusion of the PV generator affects the building, basically in terms of Power Quality.

The potential impact on public health was high, considering the fact that exposure to power-frequency magnetic fields is omnipresent. All power transmission and distribution networks, domestic and industrial wiring, and all kinds of electrical equipment give off magnetic fields. The hypothesis was taken seriously and substantial research budgets have been devoted not only to answering the important question raised by this study but more broadly to identify all other potential health effects of magnetic fields. Since 1979, an exceptional number of scientific studies have been published worldwide. In 2007, the World Health Organization published one of the most comprehensive review so far. The present article summarizes important facts regarding the interaction between a magnetic field and the human body and the key findings from this extensive research looking for a possible link with cancer.

Particularmente, en Argentina son contempladas aquellas interrupciones cuya duración sea de al menos 3 minutos. Sin embargo, para el sector industrial, los huecos de tensión resultan ser la perturbación más nociva, puesto que éstos afectan de manera directa a equipamiento sensible presente en las plantas, llegando en ciertos casos a detener el proceso de producción. Esto último, claro está, representa pérdidas económicas significativas para las plantas afectadas.

As a direct consequence, the generation of Magnetic Fields (MF) is increased due to the new power lines and cables. Magnetic Fields have raised concerns in the population for years by its association with possible health effects. Before building new facilities it is necessary to assess whether these would meet the requirements of the regulations. Thus it is necessary to have tools that quantify the MF values emitted by the planned facilities. In the laying of cables, two zones are identified. The first one is where the phases are regularly laid close to each other. The other area is where the joints are made. In this area is where the distances between phases are higher. In the latter, the magnetic field values are higher due to the increase of the separation. Trabajo C3-203. 46ª CIGRÉ SESSION (International Council on Large Electric Systems).

An unstable oscillatory mode can cause large-amplitude oscillations and may result in system breakup and large scale blackouts. There is an existent and non-operating, 345 kV transmission line between Argentinean Interconnected System (SADI) and the Northern Interconnected System (SING), which is one of the two major electrical isolated power systems in Chile with current surplus capacity and ongoing renewable energy developments. In the past, this line was only dedicated to transmit power to Chile from a power plant located in Argentina but isolated from its power system. Recently, there has been an increasing interest in restarting the operation of the 345 kV transmission line to allow the interconnected operation of both systems, SADI and SING, with growing power flows in both directions. Last year, the Company AES GENER (owner of the 345 kV transmission line and some generation plants in Argentina and Chile) received the authorization from both governments to start interconnection feasibility studies [5], to make interconnection tests and to develop operational procedures. Starting up the operation of the transmission line, in order to establish power transactions between both countries, requires the involvement of many energy market players like: system operators, transmission operators, energy policy makers, generation companies, consumers and governmental entities. The “Instituto de Investigaciones Tecnológicas para Redes y Equipos Eléctricos” (IITREE) from La Plata National University, was responsible for performing power measurements, due to the fact that according to power system studies performed by the IITREE and the “Compañía Administradora del Mercado Mayorista Eléctrico S.A." (CAMMESA), a poorly damped electromechanical oscillation in the electrical power was expected. Trabajo C2-205. 46ª CIGRÉ SESSION (International Council on Large Electric Systems).
