Description

technical field [0001] The invention relates to the technical field related to power system communication technology, in particular to a time synchronization detection method based on B code time synchronization of a collection terminal. Background technique [0002] In recent years, the B code time synchronization system is gradually being widely used in the industrial field, especially in the power system and power industry. The time information can be accurately provided through the clock synchronization of the substation, and it can be used as a fault indicator and relay protection device in the power system. , RTU monitoring system and other automation equipment provide a unified time reference and time basis, which is convenient for accurate analysis of the cause and process of the accident. Clock synchronization has become a key link in the comprehensive automation of the power grid. However, the existing B code time synchronization scheme lacks a method for detecting...
