Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

This article presents an optimization study to find the optimal partial transmission ratios for a mechanical driven system having a chain drive and a worm-helical gearbox. To find the optimum ratios, the system cross section area was selected as the target of the optimization problem. In addition, the effects of the design factors containing the total system ratio, the coefficient for calculating worm diameter coefficient, the wheel face width coefficient, the allowable contact stress of the helical gear set, and the output torque was investigated. To evaluate the influence of these input parameters on the optimum ratios, a simulation experiment was designed and conducted by computer programs. Furthermore, equations for calculating the optimum partial ratios of the systems were suggested. Based on those equations, the determination of optimum ratios can be determined accurately and uncomplicated.
With the fast growth in the switching of power electronics especially the high-power semiconductor switches with turn on/off Ability have become now available, Voltage Source Converter (VSC) subordinate control units for applications of power transmission system become a reality. In this paper, the archetypes of some of the second generation Flexible AC Transmission System (FACTS) controllers for series device types such as TSSC, TCSC, SSSC and TCSR, parallel device types such as TCR, TSC, SVC, STATCOM and SVG, and finally, compensators combined such as IPFC and UPFC have presented with analysis and effect when injected in power transmission system. This paper provides a comprehensive review of the progress made in the facts. as well as, the general illustration of the FACTS controllers is presented
