چکیده ندارد.
when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...
This study was conducted to investigate the overall efficiency of production and transmission of electricity. For this purpose, sixteen areas of production and transmission of electricity industry of Iran were selected as decision-making units. Based on Khalili and Shahmir’s model, a mathematical model was proposed that includes two stages of the production and transmission of electricity. In t...
the objective of this research is geometrical optimization of half toroidal continuously variable transmission (cvt) in order to achieve high power transmission efficiency and low weight. after dynamic analysis of the system, the contact between the disk and the roller is modeled according to elasto-hydrodynamic lubrication principles. accordingly, a computer model is created with geometric, th...
