Power distribution network power failure range analysis method

Abstract

The invention relates to a power distribution network power failure range analysis method, belongs to the technical field of power distribution network power failure first-aid repair and power supply service, and can effectively solve the problem that a power distribution network switch is not additionally provided with monitoring equipment or information of switch monitoring equipment installed outdoors fails to report. And the power failure range cannot be effectively analyzed and identified by using a traditional method. According to the power distribution network power failure range analysis method provided by the invention, the tripping probability of different circuit breakers (or switches) of the line is obtained and the power failure range is analyzed only by using the actual power loss information of the power distribution area, so that a new thought is provided for power distribution network power failure range analysis.

Description

technical field [0001] The invention belongs to the technical field of power distribution network emergency repair and power supply service, and in particular relates to a power distribution network power failure range analysis method. Background technique [0002] With the acceleration of the digital transformation of the distribution network, more and more sensing devices are widely installed in the distribution network, and the distribution network has become observable and observable from the original "blind zone". However, a distribution line, especially a rural distribution line, is generally long and involves many circuit breakers, sectional switches, fuses, and low-voltage circuit breakers in the platform area. Not all switches or circuit breakers are equipped with monitoring equipment. When a line fault occurs, a switch quickly trips to remove the fault due to overcurrent. If the switch is equipped with monitoring equipment, the operation monitoring background can r...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for analyzing the power outage range of a distribution network, which is used to solve the technical problems in the above-mentioned prior art, such as: the identification of the power outage range of a traditional power distribution network is realized according to the switch trip information and the network topology relationship, However, not all switches in the distribution network are equipped with monitoring equipment. At the same time, the switch monitoring equipment installed outdoors has information leakage. When the above situation is encountered using traditional methods, it will not be possible to analyze and identify the power outage range.
