Automatic detection platform and detection method for distribution automation terminals

Abstract

An automatic detection platform and a detection method for distribution automation terminals are provided. The detection platform includes a communication module, and a control module, an informationencryption module, a signal source 1, a standard clock module and a signal source 2 connected with the communication module, and a standard meter connected with the control module and the signal source 1. The automatic detection method for distribution automation terminals includes the following steps: according to the detection information of a pre-established detected distribution automation terminal, configuring a detection case of the detected distribution automation terminal, forming a control instruction in the detection process, and generating a detection signal; and carrying out calculation, comparative analysis and evaluation according to a received response signal of the detected distribution automation terminal and the operation condition of the detection platform. The function,performance and protocol consistency of multiple distribution automation terminals can be detected automatically and simultaneously, and the function of fault detecting and handling between multipledistribution automation terminals can be detected.

Description

technical field [0001] The invention relates to the field of power system distribution automation, in particular to an automatic detection platform and detection method of a power distribution automation terminal. Background technique [0002] With the upsurge of global smart grid construction and research, the intelligence of distribution network has become a new trend in the development of future power grids, and the distribution automation system is the cornerstone of building a smart distribution network. The smooth implementation of the distribution automation system depends on a large number of distribution automation terminals installed on site. Whether the functions and performance of the distribution automation terminals can meet the technical standards is the key to the success of the distribution automation project. [0003] In order to ensure that the distribution automation terminal equipment has complete functions and reliable quality, different types of testin...

Problems solved by technology

However, at present, for the detection of power distribution automation terminals, it mainly relies on the testing personnel to use multiple testing instruments and equipment to carry out item-by-item testing of their functions and performances. Every time some testing items are completed, the test wiring needs to be changed again.

The whole detection process has a large amount of manual participation and a low degree of automation, which seriously reduces the detection efficiency

In addition, there is a lack of unified supervision and control over the testing progress of the tested equipment, the work management of the testing personnel and the testing quality

[0004] In recent years, although testing institutions at home and abroad have made some breakthroughs in the automatic testing of distribution automation terminals, they have only realized the automatic testing of the "three remote" basic functions and "measurement accuracy" of distribution automation terminals. , failed to realize the communication and communication protocol, time synchronization and punctuality, information security detection, fault detection and processing and other functions of the distribution automation terminal, as well as the performance of the influence quantity test of the AC analog input and the environmental influence quantity test. Automatic detection

In addition, in terms of the large-scale detection capability of distribution automation terminals, it is still impossible to meet the working requirements of simultaneously detecting multiple distribution automation terminals
