Electric energy quality monitoring terminal simulator

Abstract

The present invention proposes a power quality monitoring terminal simulator, the simulator includes an HMI human-computer interaction module, a control module, a modeling module, an IEC 61850 server and a database; the power quality monitoring terminal simulator is connected to a power quality monitoring master station; The HMI human-computer interaction module, the control module, the modeling module, the IEC 61850 server and the database are connected in sequence. The present invention simulates the communication behavior of all terminals in the entire power quality monitoring system, which can save test equipment, reduce test costs, and shorten the test cycle; through the terminal simulator test, it can ensure that the function and configuration of the power quality monitoring master station are correct, thereby The seamless communication between the actual power distribution terminal and the client system is realized, which ensures the accuracy and reliability of the data transmission of the entire power quality monitoring system. The invention is simple in configuration, easy to implement, and can be quickly configured to complete the input test.

Description

technical field [0001] The invention relates to a detection device, in particular to a power quality monitoring terminal simulator. Background technique [0002] The power quality monitoring master station has the functions of processing, storing, counting, analyzing, generating reports, and publishing information on power quality index data such as voltage, frequency, harmonics, interharmonics, unbalance, voltage fluctuations, and flicker. Generally, it is necessary to fully test the functions and performance indicators of the completed power quality monitoring master station. It is a very important and complicated work to fully test the system functions and performance indicators of the power quality monitoring master station. At present, in the actual engineering test, various power quality phenomena simulated by the test instrument are input into the power quality monitoring terminal, and the power quality monitoring terminal receives and processes the information and s...

Problems solved by technology

This test method has the following disadvantages: 1. A special test environment must be set up, and the correctness of the ICD model provided by each power quality monitoring terminal can only be verified through the point-to-point test of the test instrument

2. It is impossible to simulate the network communication load value of the entire power quality monitoring system

3. It is impossible to conduct a comprehensive test on the power quality monitoring master station

4. The test process is greatly affected by human factors, and the test cycle is long
