A real-time monitoring method and system for power carrier communication

Abstract

The invention discloses a method and system for real-time monitoring of power line carrier communication. The method comprises the following steps that S1, electric power signal data on a three-phase power line are collected by a plurality of A / D collection devices in real time, are compressed, and then are sent to a server at the far end through a communication network; S2, the server carries out decompression on the received electric power signal data, and the decompressed electric power signal data are stored in a database in a classified mode; S3, a client has access to the database of the server to obtain the electric power signal data, and carries out analysis and locating on the electric power signal data, so that real-time monitoring is carried out on the three-phase power line on site. According to the method and system for real-time monitoring of power line carrier communication, comprehensive collection, real-time transmission and storage and convenient access to carrier wave data are achieved, the operation and maintenance cost for signal acquisition and fault locating on site is greatly reduced, and the fault early warning effect on a monitored terminal can be achieved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a method and system for real-time monitoring of power carrier communication. Background technique [0002] As a unique communication method of power system, power carrier is a technology that uses existing power lines to transmit analog or digital signals at high speed through carrier. The centralized meter reading system realizes remote automatic meter reading through power carrier technology. However, due to the complex environment of the power carrier, the carrier signal is greatly disturbed by the environment, which affects the performance of the centralized meter reading system. Once the centralized meter reading system fails, the data available for positioning and analysis is very limited; Before operation, there are few simulation verification methods and methods in the laboratory, which cannot effectively reduce the risk and cost of system operation and maintenance...

However, due to the complex environment of the power carrier, the carrier signal is greatly disturbed by the environment, which affects the performance of the centralized meter reading system. Once the centralized meter reading system fails, the data available for positioning and analysis is very limited; Before operation, there are few simulation verification methods and methods in the laboratory, which cannot effectively reduce the risk and cost of system operation and maintenance

[0003] Existing detection devices and methods for power carrier communication can only monitor some functions and solve unilateral problems, but the monitoring means for the terminal operating environment are very limited, and the collected monitoring data cannot be sent to engineers in a timely manner For example, the fault recorder only collects and saves data according to the set time and the electrical quantity to be collected before and after a system fault occurs. This monitoring method is not suitable for the location of software function defects. Engineers only Ability to go to the site for analysis in person, resulting in high maintenance costs for the system
