摘要: Some of the practical limitations on use weather-dependent thermal rating methods for overhead transmission lines are explored. A distinction is made between ratings a single span and an entire line. Based hourly historical weather data Rochester, NY, USA, it demonstrated that while probability distribution each in line similar, dependent upon orientation spans The maximum found when all parallel. Minimum whose orientations vary. Historical studied order to estimate minimum predicted 1 4 hours into future. It such not greatly excess traditional static ratings. >
