Abstract

The present invention relates to the technical field of power transmission, in particular to a pre-simulation-based intelligent dynamic capacity increase system and method for power lines, including a simulation system, a target cable monitoring device, and a control center. The simulation system obtains the conductor temperature of the cable and the temperature of the outer sheath, The function F of the ambient temperature, humidity and wind speed, the target cable monitoring device includes the outer sheath temperature monitor, the ambient temperature and humidity monitor and the wind speed sensor, the outer sheath temperature monitor monitors the outer sheath temperature, the ambient temperature and humidity monitor and the wind speed sensor Monitor the air temperature, humidity and wind speed near the target cable, and the control center obtains the conductor temperature of the target cable according to the function F. If the target conductor temperature is lower than k times the temperature upper limit, the capacity increase capacity is provided with a step size △P until the target conductor temperature k times the upper temperature limit. The substantive effect of the present invention is: obtain the dynamic maximum load through the real-time environment temperature, humidity and wind speed, provide dynamic capacity increase for the target cable, and improve the power supply capacity.

Description

technical field

[0001] The invention relates to the technical field of power transmission, in particular to a system and method for intelligent dynamic capacity increase of power lines based on pre-simulation. Background technique

[0002] With the development of economy and society, the electricity consumption of users is increasing year by year, which causes the load of some lines to approach the design load. It is necessary to build new power lines or increase the capacity of existing lines. Power lines pass through a complex environment, and a large safety margin is usually left in the line design. Moreover, the capacity of line capacity increases varies with the environment. At present, there is a lack of dynamic control technology for line capacity expansion, and the potential of line capacity expansion cannot be effectively utilized.

[0003] For example, Chinese patent CN104330659B, published on February 15, 2017, is a quasi-dynamic capacity increase method based o...
