Adaptive reciosure by judging secondary arc is a reclosing way that focuses on reliability. It distinguishes reclosing lockout by measuring the amount of extinguished arc characteristics of line. Generally, the research of adaptive reciosure is based on unmistaken judging and act of reclosure system, ignoring the potential harm that reciosure could misact in permanent fault that affect transient stability. Beacause transient energy of system after a fault trip fluctuates with the growing time. When locking the system of reciosure that causes large impact basing on the distribution of transient energy of timeline, it can greatly reduce impact of transient stability of system that is caused by the fluctuations of detectable amounts,detection error and equipment malfunction under the effective application of adaptive reciosure methods. The results of simulation show that the method has a more significant improvement than the original method in anti misoperation and reliable latching.
