Power line intelligent dynamic capacity increasing system and method based on pre-simulation

Abstract

The invention relates to the technical field of power transmission, in particular to a power line intelligent dynamic capacity increasing system and method based on pre-simulation, and the system comprises a simulation system, a target cable monitoring device and a control center. The method comprises: the simulation system obtaining a function F of the conductor temperature of the cable on the outer sheath temperature, the environment temperature and humidity and the wind speed; the target cable monitoring device comprising an outer sheath temperature monitor, an environment temperature and humidity monitor and a wind speed sensor, the outer sheath temperature monitor monitoring the temperature of an outer sheath, the environment temperature and humidity monitor and the wind speed sensor monitor the temperature, humidity and wind speed of air near the target cable, and the control center obtaining the conductor temperature of the target cable according to a function F; and if the target conductor temperature is lower than k times of the upper temperature limit, providing the capacity increasing capacity at the step length P until the target conductor temperature exceeds k times of the upper temperature limit. The method has the substantive effects that the dynamic maximum load is obtained through the real-time environment temperature and humidity and the wind speed, dynamic capacity increasing is provided for the target cable, and the power supply capacity is improved.

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...
