Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0050] Such as figure 1 As shown, it is a flow chart of the present invention. The present invention is based on the measurement data of the AMI system, user information, and the topological structure data of the medium and low voltage distribution network provided by the GIS system, and uses the ant colony algorithm to perform path search and target research and judgment. Including: function triggering, initial data preparation, ant colony fault research and judgment process, and fault information notification and forwarding. The following is a description of the four links:

Abstract

The invention discloses a method for studying and judging a power distribution network power failure. The method comprises the steps that power failure and decompression users are screened, and powerdistribution network topology of the power failure and decompression users is acquired; an ant colony is set up for the power failure and decompression users, and an overall path matrix is set up according to the power distribution network topology; ant colony distribution is judged to determine a subpath matrix of ant colony search and serves as a sub-information prime matrix; fault search is carried out through an ant colony algorithm, all ants in the ant colony are subjected to path search, and element values of the sub-information prime matrix are updated synchronously; it is adopted as aterminal condition that all the ants are judged, and the largest element value in the sub-information prime matrix is the power failure point. According to the method, under the condition of not increasing hardware investment cost, the speed of failure locating is increased, the accuracy of failure locating is improved, the response time is shortened, the cost is reduced, and the customer satisfaction degree and the system operation index are improved.

Description

technical field [0001] The invention relates to a method for researching and judging a power outage fault of a distribution network, and belongs to the technical field of distribution networks. Background technique [0002] Since the introduction of the smart grid in 2009, my country has comprehensively promoted the construction of smart distribution networks, and the automation level of the grid has been continuously improved. At the same time, users have raised higher requirements for the reliability and quality of power supply services. Positioning has also become a hot spot of research attention. [0003] For a long time, for low-voltage side fault information, the power supply company has mainly used the repair calls of residents, used the power outage management system to handle low-voltage lying network faults, and predicted the location of the drop insurance or switch based on the calls made by users after the power outage. Analyze the personnel strength and emergenc...
