Fault analysis system for optical fiber differential protection

Abstract

The invention discloses an optical fiber differential protection fault analysis system, which includes a one-to-two optical splitter, a two-in-one combiner, a differential protection A, an optical fiber channel 1, a differential protection B and an optical fiber channel 2. The fiber optic differential protection fault analysis system developed by this project provides a strong basis and guarantee for quickly and accurately troubleshooting power grid faults, provides a one-stop solution for fault analysis for operation and maintenance personnel, and provides efficient and accurate fault analysis for operation and maintenance personnel Analysis means, through this system, the cost of employee fault analysis and status monitoring can be reduced by 50%, and the cycle can be shortened by 50%. Through the implementation of this project, it can provide staff with accurate and reliable fault information in time, so as to improve the staff's understanding of faults. The working efficiency of the processing can restore the power supply of the system as soon as possible, reduce the comprehensive economic loss caused by the failure, and thus improve the safe and stable economic operation level of the entire power system.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a fault analysis system for optical fiber differential protection. Background technique [0002] With the development of optical fiber communication technology, optical fiber has been more and more widely used in the relay protection of power system. Advantages, especially the simple criterion and quick action of optical fiber differential protection, which greatly improves the reliability of the main protection. In order to use fiber optic channels, regional security and stability control devices need to exchange information such as inter-plant lines and unit start-up and stop status, operating power, protection actions, etc., and most of them use fiber optic channels as the carrier of information exchange. [0003] Although Fiber Channel is safer, more reliable, and easier to maintain than high-frequency channels, with the increasing use of Fiber Channel in l...
