摘　　要：随着城市建设经济发展速度加快,用电负荷持续增长,与此同时,制造产业的升级对电网供电可靠性提出了更高要求。为应对日益增长的供电可靠性要求,除了持续建设电网网架结构之外,一个科学的、合理的电网运行方式安排也具有举足轻重的影响。面对供电可靠性较高的双回线路供电网架,在负荷侧为单母线接线时,通常电网运行方式只依照单一元件N-1的情况考虑母线挂接方式安排,则进一步考虑保护非正常动作情况,对双母线厂站双回线路供电单母线厂站情况下的双回线路母线挂接方式进行了更加细致的分析探讨。最终给出一个可行的母线挂接方式规则。With the expansion of urban scale,electric load is increasing continuously.In order to meet the needs of the requirements of power supply reliablility,set up a scientific and rational power network operation way.Face with two-circuit power supply lattice frame of higher reliability power supply,when the load side is single bus wiring,in general,the power network operation way is only considered the bus hanging way arrangement according to single element N-1.Protecting improper action conditions are further considered in the paper,analyze and discuss the two-circuit hanging way for the two-circuit bus power supply of the two-circuit station and single bus station.Finally,give a practical bus hanging way rule.
