upgrading the voltage level of a transmission line is named as one solution to increase the transmitted power. this paper introduces the results of a research project in which the upgrade of saravan-sooran double circuit transmission system from 63 kv to 230 kv is studied. in this context, the towers remain in their current locations, where the new structure of towers and insulators as well as ...

As a new power transmission technology, magnetically coupled resonant wireless power transmission technology can achieve mid-range wireless power transmission with the advantage of high transmission efficiency. As known, the driving source has a significant impact on the overall performance of wireless power transmission system. With this consideration, a pulse-driven magnetically coupled reson...

Because the power systemload the randomness of the nature, power transmission of AC induction system has the low efficiency. In order to improve the transmission efficiency,the transmission efficiency influenced factors of the system is analyzed. Based on the current source power transfer system, DC/DC circuit for dynamic adjustment method is proposed. The method ensures that the transmission e...
