Power distribution terminal side automatic debugging method based on field mobile terminal and analog main station

Abstract

The invention relates to a power distribution terminal side automatic debugging method based on a field mobile terminal and an analog main station. The method comprises the steps of 1, building a power distribution terminal side automatic debugging system; 2, acquiring a sequence table transmitted from the power distribution terminal by the analog main station from a three-area pre-database of a power distribution automatic system, and grouping each sequence table by the analog main station; 3, establishing an HTTP connection by the field mobile terminal to the analog main station, and acquiring the power distribution terminal grouping sequence table of an affiliated administrated area according to an authority distribution rule; 4, performing communication between the field mobile terminal and a relay protecting tester; 5, setting the initial value of the automatic debugging parameter of the power distribution terminal by the field mobile terminal; and 6, selecting the to-be-tested power distribution terminal, and starting independent automatic debugging at the power distribution terminal side. The power distribution terminal side automatic debugging method has advantages of no requirement for actual power distribution main station side artificial cooperation, high working efficiency, flexible debugging sequence and high debugging accuracy. A debugging result is automaticallygenerated and a debugging report can be conveniently checked. The system can be carried with personnel for reducing load of the personnel, thereby further improving working efficiency.

Description

technical field [0001] The invention belongs to the technical field of power system distribution network automation, and in particular relates to an automatic debugging method at the power distribution terminal side based on an on-site mobile terminal and a simulated master station. Background technique [0002] With the development of digitalization, informatization, automation, interaction and intelligence of the distribution network, the requirements for the commissioning efficiency of the distribution terminal are getting higher and higher. During the construction and operation and maintenance of the distribution automation system, when the distribution terminal is installed and debugged, the on-site personnel cannot directly know the correctness of the telemetry data sent to the actual distribution master station system.

Problems solved by technology

During the construction and operation and maintenance of the distribution automation system, when the distribution terminal is installed and debugged, the on-site personnel cannot directly know the correctness of the telemetry data sent to the actual distribution master station system. The transmission test is mainly done manually, and both the power distribution terminal and the actual power distribution main station need to check each remote signal and telemetry information point by point by phone, which not only has a large workload and low efficiency, but also causes a great waste of personnel and time. It is also easy to make mistakes due to inconsistencies in the descriptions of the two parties.

In view of the above problems, an existing improvement method is to formulate a series of standardized debugging standards, including the order of data transmission, the value of remote measurement, etc., the power distribution terminal side is responsible for sending the signal, and the actual power distribution master station system receives the debugging The data is compared with the debugging standard defined in advance to confirm the correctness of the debugging information. Although this method can achieve the purpose of automatic debugging, it still needs the cooperation of both sides, which is less flexible, and the main work is concentrated on the actual On the power distribution master station side, the commissioning standards and configuration work are all in charge of the actual power distribution master station personnel, and the actual power distribution master station personnel have a heavy workload

The workload of these two debugging methods is very large, and it adds a lot of maintenance work to the user, which is not conducive to the large-scale construction and promotion of distribution automation systems.

[0003] In addition, the above two methods have a low degree of automation. The former is completely operated manually. Although the improved debugging method has formulated a series of standardized debugging standards, it needs to be manually configured for each power distribution terminal, and the automatic joint debugging is started and closed. It also needs to be manually triggered by the actual power distribution master station side
