At the same time, the paper uses the spot price expression based on security region, which takes the consideration of transmission line thermal stability constraint and static voltage stability constraint and transient stability constraint simultaneously, thus the main security constraints of power system can be considered comprehensively in the security cost allocation.

同时，该文使用基于安全域的节点电价表达式，其中计及了输电线路热稳定约束、系统的静态电压稳定约束和暂态稳定约束，使安全成本的分摊能综合考虑电力系统中主要的安全约束。

The transmission lines designed according to standard are supposed to be secure in practical operation, however, since the second generation of transmission towers for 500kV transmission line are put into operation, the incidence of windage yaw flashover increases year by year, and it is unreasonable theoretically.

按照标准设计的输电线路在实际运行中应该是安全的，但自从500 kV 输电线路第2代杆塔投入使用以来，风偏闪络事故的发生率逐年上升，这在理论上分析是不合理的。

To go through the power line protection zone at a distance smaller than the safety distance between conducting wires and the objects to run through.

After transformation,line protection can select phase correctly when cross country fault occurs,the transmission of protection signals can be more reliable and rapid in optic fiber channel,to provide more.

改造后，线路跨线故障时保护能正确选相，保护信号通过光纤通道能更可靠快速地传输，为500 kV线路更加安全稳定运行提供保障。

All of these show that high voltage insulator pollution flashover is a serious threat to the safety and the reliability of the electric power net.

因此，研究高压输电线路绝缘子污秽在线监测技术，对提高输电线路的安全可靠性具有重要意义。

In recent years, lightning stroke is one of the important causes of the accidents that occur on transmission lines. With the increase of voltage grade of transmission line, the proportion of outages because of shielding failure also increases. Therefore, exactly evaluating lightning-withstanding level and shielding failure flashover rate of transmission line, is especially important for system service and stable operation.

雷击是引起线路故障的重要原因之一，随着电压等级的升高，由于绕击而引起的线路跳闸事故所占的比例也越来越大，因此准确评价线路的绕击耐雷性能对于电力系统的安全稳定运行有着重要的意义。
