一种高压输电线路安全投运方法及系统
摘要：
本发明公开了一种高压输电线路安全投运方法及系统。所述方法包括：获取高压输电线路投运安全的影响指标，影响指标包括电压大小、负载大小、线路可靠性、负载重要性和投资成本；获取每个影响指标分别对应的权重；获取电压大小、负载大小、动作可靠性、设备可靠性、负载重要性和投资成本分别对应的基础影响因数；获取在预设的极寒温度下动作可靠性的影响因子和设备可靠性的影响因子；获取线路投运安全指标和线路投运经济指标；获取线路投运安全评估因子；判断线路投运安全评估因子是否低于预设阈值；如果是，则继续投运；否则，停止投运。本发明考虑了极寒条件对于高压输电线路投运的影响，能够提高高压输电线路投运的安全性和电网的可靠运行能力。
摘要（英）：

The invention discloses a high-voltage power transmission line safety commissioning method and system. The method includes: obtaining influence indexes of commissioning safety of high-voltage power transmission lines, wherein the influence indexes include the voltage, the load, the circuit reliability, the load importance and the investment cost; obtaining the weight corresponding to each influence index; obtaining basic influence factors respectively corresponding to the voltage, the load, the motion reliability, the equipment reliability, the load importance and the investment cost; obtaining an influence factor of the motion reliability and an influence factor of the equipment reliability at a preset extremely cold temperature; obtaining a line commissioning safety index and a line commissioning economic index; obtaining a line commissioning safety assessment factor; and determining whether the line commissioning safety assessment factor is lower than a preset threshold, if yes, continuing commissioning, and if not, stop commissioning. According to the method and system, the influence of the extremely cold condition on the commissioning of the high-voltage power transmission lines is considered, and the commissioning safety of the high-voltage power transmission lines and the reliable operation capability of a power grid can be improved.
