Audible noise predicting formulas and reduction measures for 1 000 kV UHV AC transmission lines
摘要
Abstract
Several audible corona noise predicting formulas of UHA transmission lines,founded by BPA from the U. S. A. ,ENEL from Italy and EPRI from China etc. ,were introduced. Based on the conductor parameter of Huannan-Shanghai 1 000 kV UHV AC double-circuit transmission line,four formulas were presented for pre-dicting the audible noise of the same type transmission lines exactly. The factors resulting in audible noise of UHV AC transmission line are analyzed,including the structure,design and construction of the transmission line, as wel as the atmosphere and environments. The measures to reduce audible noise of transmission line were summed up,and such engineering solutions to reduce the audible noise as increasing the diameter of bundled conductors,increasing the bundle numbers and changing the interval between bundled conductors are consid-ered applicable. Some preventive suggestions ale provided in the hope of supporting on-site operation data for designs of 1000kV UHVAC transmission lines,operation and maintenance.关键词
