Embodiment Construction

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] as shown and figure 2 As shown, it is a schematic diagram of an embodiment of a self-healing method for a distribution line fault provided by the present invention. In this embodiment, the method includes the following steps:

[0031] When the distribution line fails, the protection device of the fault current flowing through the distribution network switch controls the distribution network switch of the level difference protection at the upper level of the fault area to trip according to the preset level difference configuration strategy; that is, for different distribution line configurations Reasonable differential protection strategy configuration; when the distribution line fails, the protection device of the fault current flowing through the dist...

Abstract

The invention provides a distribution line fault self-healing method which comprises the following steps: when a distribution line has a fault, fault current flows through a protection device of a distribution network switch to control tripping of the distribution network switch of level difference protection at the upper level of a fault area according to a preset level difference configuration strategy; the distribution network master station starts a preset self-healing action according to the fault information sent by the power distribution terminal and controls the preset differential protection to cooperate with the feeder self-healing action to carry out line fault processing at the same time; and judging whether the line fault is processed or not according to the line fault processing state acquired in real time, and when the line fault is processed, judging that the self-healing action is finished by the distribution network master station. According to the method, the requirements of small power failure range and short fault handling time of the distribution line are met, the feeder self-healing action effect is further optimized, and the power supply reliability is improved.

Description

technical field [0001] The invention relates to the technical field of self-healing of power distribution line faults, in particular to a self-healing method of power distribution line faults. Background technique [0002] At present, the self-healing of the external feeder of the distribution network is mainly realized in three ways: centralized, local, and cooperative. The master station and the intelligent distributed coordination, the master station and the voltage / current / time type coordination are mainly. From the perspective of taking into account the scope of power outage and the short fault time, the above modes all have certain defects: 1. The centralized type has the characteristics of strong reliability, short operation time, and easy operation and maintenance, but generally relies on the tripping of the outgoing switch of the substation to start fault handling , the power outage range is large; 2. The differential protection on-site self-healing has the charact...
