Abstract
Transmission line dynamic rating method as an important part of the inteligent transmission technical system can effectively solve the problem of insufficient power supply capacity of transmission lines. In this paper,the overal scheme of the dynamic rating method is briefly ilustrated. Next,transmission lines real-time monitoring technology and transmission line dynamic rating method are described respectively. Finaly,the influence of external factors on carrying capacity of transmission lines is analysed. Numerical results show that the proposed dynamic rating method is very effective.
