15. Sleep, ageing and night work
Studies have shown that the frequency or worsening of sleep disorders tends to increase with age and that the ability to perform circadian adjustments tends to decrease in individuals who work the night shift. This condition can cause consequences such as excessive sleepiness, which are often a factor in accidents that occur at work. The present study invest

18. AVALIAÇÃO E REFORÇO DAS CONDIÇÕES DE ESTABILIDADE DE TENSÃO EM BARRAS DE TENSÃO CONTROLADA POR GERADORES E COMPENSADORES SÍNCRONOS / VOLTAGE STABILITY ASSESSMENT AND ENHANCEMENT IN VOLTAGE-CONTROLLED BUSES BY SYNCHRONOUS GENERATORS AND COMPENSATORS
After the incidence of some voltage collapses in the energy transmission systems in the world, the voltage security became an issue of great interest in the last years due to the importance of its impact. The phenomenon of voltage stability is due to the excessive active and reactive power flow in the electrical transmission network and has been associated w

19. Avaliação dos Impactos da Impedância de Falta e da Geração Distribuída em Estudos de Afundamentos de Tensão / Impact Assessment of Fault Impedance and Distributed Generation Studies of Voltage Sags
This work presents an impact analysis of the fault impedance and distributed ge- neration on the amplitude and annual average quantity of voltage sags in sensitive end-users. Phase-to-ground solid and non-solid faults were simulated in 62 transmission lines at 230, 138, 69 and 13.8 kV, which made part of the electrical system of the municipality of Goiânia,

20. Estabilização de oscilações de potencia de linhas de intercambio atraves de um elo de corrente continua / Stabilization of power lines interchange oscillations through a direct-current link
When an interconnected alternate-current power system suffers variations of loads, its frequency can exhibit an oscillatory behavior. If this system possesses a direct-current link in parallel with the inter-tie lines, this effect could be decreased, due to the link current controller action. This work presents a study that evaluates the efficiency of DC lin
