Bancos de capacitores se corrente de Inrush

This work discusses about the effects and methods of control and elimination of the currents transients generated by switching capacitor banks, this currents are called inrush currents. Capacitor banks are widely used to compensate a low power factor generated by the widespread use of inductive loads. Currently many of these banks are automatic and therefore the capacitive cells are connected and disconnected according to the inductive loads on the network. However when connecting a capacitor bank to a bus can generate currents transients generated by electromagnetic transients. Aspects of the network, for example, the existence of a bank already connected to the bus, can influence the intensity of this phenomenon. This paper discusses some characteristics of the capacitors and the network to justify and explain the appearance of these transients and discusses its effects on the network and to other equipment. It is concluded that the main cause of this phenomenon is the voltage difference between the capacitor to be connected to the network and the bus, the results of the study were the bases to discuss the traditional methods to mitigate these currents and therefore its negative effects. Although in this paper is yet developed a method of electronic switching that can greatly reduce these transients

Estudo da malha urbana e proposta de implantação de um parque tecnológico na cidade de Jacareí

The city of Jacareí above average presents a economic growth of the State of São Paulo, fact that comes if reflecting in the quality of life of the citizens, due to lack of infrastructure to hold the growth rhythm. Today the commercial center of the city, presents diverse urban conflicts with its narrow streets and sidewalk making it difficult to the locomotion and the access the areas and building of public interest gifts in this region. Aiming at the arrival of four multinationals that already make gratings investments in the city and the promise of growth and dinamização of the still bigger economy for the next years, this work studies the urban mesh of the city for a possible implantation of a Technological Park that serves of inductive element of the development of the region north of the city of Jacareí. Place, in which, they are being constructed the multinationals and where, according to Managing Plan of the city, the city hall intends to urbanizar in the next years, with the objective to minimize the areas of urban conflict in the commercial center and of form to absorb the growth of the city. From the study of old experiences, of works carried through on the subject, interviews with city planners of the e region after visits to the place, we will go to argue the possibility of implantation of the Technological Park in Jacareí and optimum place for its installation

A crença religiosa sob a perspectiva semiótica de Peirce

Current paper presents the relationships between beliefs, specifically religious ones, and the Peirce’s theory of interpretants. It is assumed that religious belief emphasizes the emotional aspect of faithful, preventing criticism and change of habit. According to the author, the nature of cognition is contrary to the determination of this kind of belief since it is based on the method and fallibility of hypotheses. It is not enough for the method to deduce its consequences but seeks the inductive verification of their results in the long run and through the community of beings who thinks through signs. The problem of religious belief is the acceptance of a transcendent world and intuition which guides behavior. The vague idea of God is not submitted to scientific hypotheses but, engendered by religious systems, it creates signs whose emotional appeal is evident, redirecting it to its own target principles. Therefore, is repeats the success achieved in the past by dogmas, which were effective to appease the anguish of the believer and reproduce order. Knowledge should not have any boundaries because it is grounded on the method and cognition of reality.

Energetic exploitation from a hybrid PV-wind power micro-generation rural electrification

Hybrid system micro-generation integration of PV-wind power is presented by a form of energy in which problems resulting from variability in the intensity of wind and solar intensity are possible mitigation either by complementation between one source to another or the largest stability configured by the generate the system. Based on this context, this work aims to assessing the performance of a hybrid system PV-wind power energy small of a rural property for their electrification. The study has been developed at the Rural Laboratory Powering from Engineering Department of UNESP. In order to present this research, a hybrid system has been installed PV-wind power, composed of one 400Wp windmill and a 300 Wp PV-system. The results obtained allowed us to evaluate the solar and wind energy supplied ranked among 285 and 360 kWh electric power generated by the PV-wind power hybrid system stood between 25,5 and 31 kWh. At is to say achieving yield of approximately than 10% during one year observation period, i.e., it was concluded that the performance of the hybrid system depended essentially the energy received and generated by the PV-system and that there was complementation between generating wind power and PV-systems with regard to time of day and the annual seasons by confirming the technical feasibility of this kind system of micro-generation in small rural properties.

Development and test of resistive superconducting fault current limiter; acting time and its recovery conditions

Resistive-type of superconducting fault current limiters (RSFCL) have been developed for medium voltage class aiming to operate at 1 MVA power capacity and short time recovery (< 2 s). A RSFCL in form of superconducting modular device was designed and constructed using 50 m-length of YBCO coated conductor tapes for operation under 1 kV / 1 kA and acting time of 0.1 s. In order to increase the acting time the RSFCL was combined with an air-core reactor in parallel to increase the fault limiting time up to 1 s. The tests determined the electrical and thermal characteristics of the combined resistive/ inductive protection unit. The combined fault current limiter reached a limiting current of 583 A, corresponding to a limiting factor of 3.3 times within an acting time of up to 1 s.
