摘　　要：交流线路的跳闸判据在各级电网的安全稳定控制装置中得到了广泛应用,跳闸判据的准确性不仅依赖于判据本身设计的可靠性,还与二次回路的正确设计和定值的正确整定密不可分。以实际工程为例分析了并联高抗对于稳控装置跳闸判据和定值整定的影响,提出了包括输电线路的二次回路设计方案及定值计算、整定方法在内的解决办法,并通过工程实例进行了说明。Trip criterion of AC transmission line has been widely used in power system security and stability control equipment.The correctness of fault trip criterion not only depends on the reliability of the criterion,but also depends on the secondary loop and fixed value setting.By taking the actual project as an example,the influence on line fault trip criterionexited problems are analyzed.The solutions including the secondary loop design scheme and setting calculation are put forward,and are demonstrated by engineering practice.
