Description

Intelligent power grid acquisition method based on relay equipment

Technical Field

The invention relates to the field of intelligent power grid acquisition, in particular to a power grid intelligent acquisition method based on relay equipment.

Background

The intelligent acquisition of the power grid is to read and control all data (including an extended data identification set), broadcast timing, switching on and switching off control and other instructions of a user electric energy meter by a power company in a communication mode of low-voltage power line carrier, micro-power wireless and the like at present. However, with the increase of users, the current power utilization and wiring of some transformer areas are complex, the power utilization data of users in the island transformer area, the long-distance transformer area and the complex noise transformer area under the traditional intelligent acquisition network structure are difficult to acquire, the accurate calculation of the line loss of the transformer area cannot be realized, and the occurrence of electricity stealing situations cannot be judged.

The traditional intelligent collection of the power grid is composed of a communication module or communication equipment for local communication between a power consumer electricity consumption information collection terminal and an electric energy meter, and the collection method is that the collection terminal issues electric energy meter data reading and control instructions through carrier waves, and then response data information of the node electric energy meter communication module or communication equipment is returned to the collection terminal. The mutual response between the acquisition terminal and the electric energy meter communication module or the communication equipment forms a traditional intelligent power grid acquisition network. However, under the conditions of certain communication interference and signal attenuation in long-distance transmission, the traditional power grid intelligent acquisition method is greatly limited, the success rate is low, and even an island area is formed when the acquisition terminal is not communicated with the electric energy meter communication module or the communication equipment. The method for solving similar problems at present mainly comprises the following steps: 1. the method consumes a large amount of manpower and material resources and has the risk of human errors when the communication module or the equipment of the electric energy meter which fails in communication is manually read; 2. by independently setting a new platform area, the platform areas are increased, the difficulty of identifying the platform areas of the smart power grid is improved, the platform areas are possibly disordered, and reading data are unstable. The method can increase the cost of manpower and material resources when long-distance transmission or excessive interference is caused on an intelligent power grid line, and the problem of reading errors or disordered distribution areas can be caused by the solution.
