摘　　要：针对甘肃省750 kV嘉酒电网现状,对750 kV线路、主变压器、母线逐一进行N-1、N-2故障分析,提出了嘉酒电网存在的安全隐患。对照国务院599号令事故分级标准、国家电网公司安全事故调查规程,明确了安全隐患的事故风险等级。结合嘉酒电网实际情况和发展规划,提出了近期和规划期治理措施,可有效提高电网的安全可靠性。In view of the current situation of 750 kV power grid in Jiajiu power grid of Gansu province, ＂N-1＂ and＂N-2＂ fault analysis methods are adopted to analyze the 750 kV line, the main transformer and the bus bar, and put forward the potential safety problems in the 750 kV Jiajiu power grid. According to The Accident Grading Standards of The State Council Degree 599 and the Safety Accident Investigation Procedures of State Grid, the potential safety hazard and accident risk level in Jiajiu 750 kV Power Grid is confirmed. Combined with the actual situation and development plan of Gansu Jiajiu power grid, the short-term and long-term control measures are put forward individually. The proposed measures have been adopted by the operation and planning departments, effectively improving the safety and reliability of the power grid.
