摘要
根据500kV伊冯大输变电系统的实际参数，对零起升压过程中系统各处电压及无功补偿情况进行分析计算，并对一些可能出现的异常情况作了分析，提出了防范措施，使该系统零起升压试验安全平稳进行。
According to the actual parameters of the Yi - Feng - Da 500kV transdrission, thesystem voltage and reachve power comPensation are analyZed and calculated during the courseof raising voltage from zero. Some abnormal possibilities that may occur are also analyzed, andpreventive measures are proposed to make the voltage raising from zero experiment of the systemcdried on smoothly.
