Abstract

The invention discloses a method for monitoring dynamic capacity-increase Morgan current-carrying capacity of a power transmission line. The method includes the steps: (1) steady-state meteorological data of the power transmission line and conductor steady-state temperature parameters are collected in real time and sent to a monitoring center; (2) the monitoring center computes conductor steady-state current-carrying capacity by the aid of a conductor steady-state current-carrying capacity computational formula according to the steady-state meteorological data and the conductor steady-state temperature parameters obtained in the step (1); and (3) the monitoring center establishes a power transmission line Morgan current-carrying capacity simplified formula according to the conductor steady-state current-carrying capacity computational formula to obtain dynamic capacity-increase Morgan current-carrying capacity of the power transmission line so as to obtain transmission capacity of the power transmission line. A scheduler can refer to the result to regulate the transmission capacity of the power transmission line, the power transmission line is enabled to be in safe operation in a maximum load state, and early warning can be achieved.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment operation and management, in particular to an online monitoring technology for dynamic capacity expansion of transmission lines, and in particular to a monitoring method for dynamic capacity expansion of power transmission lines with Morgen ampacity. Background technique [0002] At present, in recent years, with the continuous and rapid growth of my country's national economy, the social demand for electricity has also increased rapidly. Since the transmission capacity of some transmission lines is limited by thermal stability quotas, the power supply capacity of the power grid is severely restricted, and the construction of new line corridors requires a large investment and a long construction period. Therefore, in the actual situation of existing transmission lines, how to scientifically and safely realize the potential mining of line transmission capacit...
