Research To Lightning Protection Safety Evalution Index Of Transminssion Line

With the rapid development of national economy, the ceaseless progress of science and technology, now for the electricity demand is growing, but also on the reliability of the electricity put forward higher requirements, the state has attached great importance to the construction of electrified wire netting, requirement each power supply the company constantly improve the power network structure. As the connection of the power plant and substation main hub, transmission line as the body of a person within the artery, power will be sent to all everfount. According to the statistical effects of grid structure stability factors, mainly transmission line fault tripping.Based on the transmission line lightning protection principle and application research:According to the Guangxi special climate conditions, lightning activity to carry on the analysis, elaborated the lightning activity on the industry impact.According to the line corridor surrounding terrain, lightning activity and other types of data analysis, chooses the corresponding calculation model and the method, using VB program to calculate, thereby forming each tower lightning protection index.According to the engineering example for lightning protection of transmission line is calculated, the intuitive on line lightning protection grade assess, which proposed targeted, economical measures of lightning protection of transmission line, reduce the probability of failure.Finally, through the actual engineering example of transmission line lightning protection index management system feasibility, for electric power design and operation in the actual transmission line lightning protection measures for reasonable use of references...
