Estudo da utilização do balanced scorecard na gestão da qualidade e excelência operacional aplicadas a projetos de engenharia em sistemas de potência

The expansion of the electrical system is currently a subject of great importance to the development of Brazil. For its realization, large projects are needed, requiring large-scale investment and realization processes of great complexity. Thus, this type of project has a high strategic importance for the performance of companies that conduct. Seeking a way to determine a method to align traditional practices for measuring quality to the corporate strategic needs, this work is the study of the use of the balanced scorecard methodology, applying quality management and operational excellence, with a focus on projects in power systems. We analyzed some cases of successful application of the methodology in business segments in the next study, culminating in a proposed model of the method

Efeito do exercício prévio na determinação da potência crítica

The objective of this study was to analyze the influence of previous exercise on the determination of critical power (CP). Seven apparently healthy nontrained males, of 18 to 25 years, participated of this study. The subjects were submitted, in different days to the following protocols in a cyclergometer: 1) one progressive test until voluntary exhaustion for the determination of lactate threshold (LL), maximal oxygen uptake (VO2max) and its corresponding intensity (IVO2max); 2) six constant workload tests at 95,100 and 110% IVO2max until exhaustion with and without a previous exercise at 70% , in random order. The exhaustion times (tlim) at 95, 100 and 110% IVO2max were adjusted forme thress models of two parameters to estimate CP and anaerobic work capacity (AWC) [P=CTAn/tlim)+CP; tlim = CTAn/(P-PC); P=PC.tlim+ CTAn]. The model with the lowest standard error was considered for the estimation of CP. The tlim at 95% IVO2max was similar without (501 ± 140 s) and with previous exercise (473 ± 99 s). However, the tlim at 100% (381 ± 103 s and 334 ± 101 s) and 110% IVO2max (267 ± 163 s and 227 ± 68 s) was significantly longer with previous exercise. There was no significant difference in CP and AWCat conditions without (200 ± 27 W and 23 ± 11 kJ, respectively) and with previous exercise (212 ± 30 W and 18 ± 8 kJ, respectively). It can be concluded that the parameters of the relationship between power and time were not modified by the previous severe exercise

Transmissão de potência em corrente contínua e em corrente alternada: estudo comparativo

This paper presents a comparative study based on literature and examples in the literature, the two main technologies for the transmission of electricity at high voltage: alternate current transmission and direct current transmission. Inside the direct current transmission will be shown two technologies currently employed, transmission by current source and transmission by voltage source, contributing to a better understanding of them. The ultimate goal is to provide a text for consultation to identify key characteristics that influence the choice of future transmission lines

Elementos de manutenção de transformadores de potência

The intended purpose of this paper is to present the main commissioning tests for power transformers and the most used techniques in industrial segment, it is also discussed your results and consequences in the equipment’s normal operation. Also in this text, it is given specific information concerning a maintenance plan compatible to power transformers, with elements of preventive and predictive maintenance, exposing essential components, tests and the regulations current, showing how analyze and interpreted the results from this maintenance resources. Also in this paper is submitted the economic impact of damage to transformers and how the correct maintenance method can minimize them. The objective of this text is demonstrate the importance of the equipment and the benefits of proper maintenance, much of in financial terms as in electric system reliability

A lei e a força no regime militar brasileiro: da proscrição da frente ampla à edição do Ato Institucional n. 5

This article analyses the Brazilian political process in the period between the beginning of the government of general Arthur da Costa e Silva in March 15, 1967 and the edition of the Institutional Act No. 5 (December 13, 1968). Through the analysis of the key moments in this context, seeks to qualify the actions of the main political players in terms of their goals and strategies and assess the impact that they had on the production of authoritarian legislation.
