Abstract

The invention discloses an intelligent power distribution network terminal simulation test system and a test method thereof. The system comprises a power distribution automation master station system,power distribution automation terminal equipment and a simulation test platform, and the test method comprises the following steps: generating simulation master station parameters and simulation terminal parameters, respectively communicating with a power distribution master station and a power distribution terminal, simulating and generating data, inserting and transmitting the data to the powerdistribution master station, and monitoring the whole communication process through a human-computer interface; The system is simple in structure, flexible in testing means, convenient to monitor andcomplete and reliable in verification, simulation master station parameters and simulation terminal parameters can be generated after simple input through a guide, the time for constructing model parameters is saved, and the working efficiency is high; Man-machine interaction can be carried out through a human-computer interface, the communication process is monitored, data are set and checked, and control is executed; The simulation test platform adopts a portable design, the whole software system can be installed on a computer and communicates with an external system through a network or anexternal serial port, and the hardware system simulates FTU / DTU equipment and a simulation circuit breaker on site.

Description

technical field [0001] The invention relates to an intelligent distribution network terminal simulation test system and a test method thereof, belonging to the technical field of simulation test of distribution automation systems. Background technique [0002] With the development of smart distribution network, the number of distribution automation system access terminals is increasing year by year, including distribution switch monitoring terminal FTU, distribution transformer monitoring terminal TTU, power distribution station monitoring terminal DTU, etc. There needs to be a reasonable means to test smart terminals of different models from different manufacturers, including functional testing and performance testing; [0003] At present, when the distribution automation system is connected to the terminal, the verification methods usually used are: first, the terminal function and consistency test is performed by a third party, and second, the terminal access protocol is ...

AI Technical Summary

Problems solved by technology

The former because the third-party test software cannot truly reflect the functional characteristics of a specific master station, resulting in inconsistent results between third-party verification and on-site verification; the latter is difficult to provide because the master station system and terminal equipment are not designed for simulation testing and provide limited technical means. complete and accurate verification;

[0004] Because some irregular faults or accidents often occur during the operation of the terminal, it is difficult to analyze and accurately find the cause of the fault through the disposal or alarm of the existing master station. A system for interpretation and analysis, and at the same time provide the basis for judging whether it is a switch failure or a secondary equipment failure when the terminal fails
