Embodiment Construction
[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0045] The on-site intelligent feeder automation without delay level difference coordination method requires that the intelligent terminals of the distribution line all use circuit breakers, with three-stage overcurrent protection functions, closing when there is pressure delay, reclosing at fault locking, short-time opening and locking, Delayed automatic unlocking function, and also has ground fault judgment and protection functions.
[0046] Since the non-delay step-difference coordination method is suitable for substations with small delay margin or no delay margin, it is suitable for the coordina...
