摘　　要：在研究目前600MW机组厂用电电压等级及厂用变压器配置方式的基础上,提出了2×600MW机组高压厂用电接线的1种新方案.并对其显著特点和机组启动时的厂用电运行方式进行了分析。该方案除每台机组多设1台双卷高厂变外,其他设备配置及设备规范与目前300MW级火电厂相同。After careful study of auxiliary power voltage classes and auxiliary transformer configurations of current 600 MW units, an optimized new scheme for the high voltage auxiliary power connection of 2×600 MW units is proposed. Its prominent features and auxiliary power operation mode during unit startup are also analyzed. Except for the added high voltage auxiliary transformer for each unit, the new scheme has same equipment configuration and criterion as existing 300 MW units.
