摘　　要：随着机组容量的增大和输电线路电压等级的提高,大型发电厂电气主接线有待改进和创新,在现有的基础上进行优化,以提高电气主接线的可靠性、灵活性和经济性。大型发电厂电气主接线采用1/2接线的优化方案,可以简化接线,节约投资。但该方案在国内外尚无应用实例,如果要推广应用,有待进一步进行可靠性计算、分析、评估和论证,先行试点,取得经验,逐步推广。With increase of the capacity of units and voltage grade of transmission lines, the main electrical wiring in the large sized power plants has to be improved and renovated. It should be optimized on the existing foundation to improve its reliability, flexibility and economy. The optimized scheme with 1/2 wiring used for the main electrical wiring can simplify the connection and save the investment. But the scheme has no practical example beth in domestic and abroad. If it is intended to be popularized for application, its reliability calculation, analysis, evaluation and demonstration will be further carried out, a trial project will be required for experiences and popularization.
