Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] A method for judging the abnormal unlinking during the loop closing process of a 10KV distribution network, comprising the following steps:

[0015] First, define the two substations at both ends of the line to be closed as substation A and substation B respectively, close the hot standby 10KV contact switch on the line to be closed, and then check the active power on the outlet switches of substation A and substation B through the SCADA system. If the active power of the outlet switch in one substation is displayed as a nega...

Abstract

The invention discloses a method for judging abnormal loop opening in a 10KV distribution network loop closing process. The method can effectively solve the problems that abnormal tripping of a column station switch may occur during normal loop closing, and personnel cannot judge whether an interconnection switch tripping phenomenon exists in a line or not due to the limitation of the current structure.

Description

technical field [0001] The invention relates to a method for judging the abnormal loop disconnection in the loop closing process of a 10KV distribution network. Background technique [0002] A tie switch is installed between the 10KV distribution lines between the two 10KV distribution stations to realize the closing and unwinding of the distribution network and the transfer of loads. During maintenance, the load is transferred to power supply without power failure; during normal loop closure, abnormal tripping of the column station switch may occur. Due to the limitations of the current structure, personnel cannot judge whether there is a tripping phenomenon of the contact switch in the line. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a method for judging the abnormal disconnection of the 10KV distribution network during the loop closing process, which solves the pr...
