Intelligent power utilization system and test method based on low-voltage power line carrier

Abstract

The invention relates to an intelligent power utilization system and a test method based on a low-voltage power line carrier, which adopt a systematic verification method of multicarrier module synchronous test. In the operation process, the system allocates a logic table address of an electric energy meter according to a test scale, after the logic address of each module is completely allocated, a controller simulates a main station to issue an acquisition instruction, a test platform records data of all communication routes including a real electric meter main control module, an electric meter carrier module, a concentrator downlink communication module and a concentrator uplink module, and a test result is displayed finally by virtue of data analysis and comparison. The intelligent power utilization system can realize test on the performance of communication modules of various function units such as a system main station, an acquisition terminal and the intelligent electric meter, the fault location and the rapid reproduction function, so that a convert fault can be discovered and prevented in time, the large loss caused by the running fault of the system is avoided, and the normal work of the electric utilization information acquisition system is effectively guaranteed.

Description

Technical field [0001] The invention belongs to the field of electric energy metering, in particular to an intelligent power utilization system and a test method based on low-voltage power line carrier. Background technique [0002] The construction of the electricity consumption information collection system is an important part of the smart grid. It is an important means to achieve real-time interactive response between the grid and users, enhance the grid's comprehensive service capabilities, meet interactive marketing needs, and improve service levels. Because low-voltage power line carrier communication has the advantages of simple networking, low cost, and easy implementation, it has become the most common form of communication in the electricity consumption information collection system. With the highly informatization of social development, the electricity consumption information collection system will pay more attention to the communication between power supply companies...

Problems solved by technology

[0003] In recent years, power supply companies around the world have successively carried out the pilot construction of smart grid electricity information collection systems according to application requirements. However, due to the significant differences in the environment, the noise interference on the low-voltage power line is large, the carrier channel attenuation is large, and the time-varying phenomenon is strong. Frequent occurrences lead to unstable operation of the power consumption information collection system using low-voltage carrier communication, showing many problems such as unsuccessful parameter distribution and low collection success rate, which seriously restricts the development of smart grid two-way interactive technology and the last mile smart Realization of electricity

At the same time, when a fault occurs on site, due to the close coupling of equipment in the system, it is difficult to reproduce the fault, which makes problem analysis and fault location troubleshooting difficult. Therefore, a reliable and accurate test system and a scientific and systematic verification method are urgently needed to realize the detection of various Reproduce and simulate on-site faults to improve the analysis and processing capabilities of the power consumption information collection system
