Research On Dynamic Capacity-increase Monitoring Technology Of Transmission Lines

Today, the demanding of electricity consumption of society is increasing gradually,so how to enhance the transmission capacity of transmission lines is concerned by powerdepartment. This paper proposes the concept of dynamic increasing-capacity oftransmission lines by the relation of transmission conductor thermal capacity and currentcarrying capacity of transmission line, and proposes the thinking of monitoring systemof dynamic increasing-capacity. Because the importance of conductortemperature-monitor device, its structure is proposed. And its power supply is developedemphatically. This paper proposes the scheme that using the CT to attain the energy fromthe buses as the main power and the accumulator as the accessorial power. The results ofsimulation and experiment indicate that the power supply can meet the demand of deviceto the power.
