Abstract

The present invention discloses an equivalent wind speed measurement method based on the dynamic increasing capacity of a transmission line and a measurement device thereof. The method comprises the following steps: the step 1, measuring the historical operation data and the environment data of a transmission line through a sensor, wherein the historical operation data includes the operation time, the operation current and the wire temperature of the transmission line historical operation, and the environment data includes the environment temperature and the sunlight intensity; the step 2, fixing a wind angle, and establishing the calculation method of the equivalent wind speed; the step 3, calculating the equivalent wind speed of the operation wind speed based on the calculation method; in the step 4, performing statistical induction of the daily variation rule and the seasonal variation rule of the equivalent wind speed obtained in the step 3; and in step 5, determining the equivalent wind speed in the dynamic increasing capacity of the transmission line according to the variation range of the wind speed at morning, noon and night in one month according to the daily variation rule and the seasonal variation rule of the equivalent wind speed in the step 4.

Description

technical field [0001] The invention relates to the technical field of dynamic capacity increase of transmission lines, in particular to an equivalent wind speed measurement method based on dynamic capacity increase of transmission lines and a measurement device thereof. Background technique [0002] With the steady development of my country's economy, the demand for electricity is increasing day by day. In the case of resource shortage in transmission corridors, it is of great significance to increase the transmission capacity of existing lines while vigorously carrying out power construction to alleviate the pressure on power supply. Generally speaking, static capacity increase method and dynamic capacity increase method can be used to increase the transmission capacity of the line in a short time, but the determination of capacity increase operation capacity and allowable operation time is particularly important and critical. Some scholars believe that it is effective to...
