| 摘要 |
The invention relates to a method for monitoring a high-voltage electric current transmission line, comprising the following steps: predetermining (100) an ampacity (A) of the high-voltage line from a distribution temperature, conduction parameters, and meteorological parameters; measuring (202) a current strength actually transmitted by the high-voltage line using a sensor; and monitoring (204), by means of a monitoring device that is connected to the sensor, the event of the measured current strength exceeding the ampacity (A. The step of predetermining (100) the ampacity (A) comprises: selecting (108, 110, 112, 114, 116) a value of said ampacity (A) by optimising a probability of exceeding the distribution temperature, said probability being defined on the basis of a joint probability model (P) of operating current strength and temperature that depends on meteorological parameters; and recording (118) the selected ampacity value in a storage means of the monitoring device. |
