Time correction method for multi-data-source voting mechanism based on mode principle

Abstract

The invention provides a time correction method of a multi-data-source voting mechanism based on a mode principle, the time correction method is applied to a time correction system, a clock data reading port of the time correction system is electrically connected with a main clock system, and the main clock system is composed of a plurality of groups of clock sources. Wherein the main clock systemis connected with an expansion system and a plurality of time service terminals, the expansion system is provided with a plurality of expansion devices, a data transmission port of the time correction system is also electrically connected with a station control layer system and a gateway, and the time correction system is connected with a scheduling system through the gateway. According to the method, the time of various data of all automation equipment and a computer server in the transformer substation can be unified, so the data can work under a unified clock signal, and an accurate, safeand reliable time reference is provided for the operation data of various equipment in the transformer substation so as to meet the requirement of time synchronization; in addition, all related data information is accurately applied to a transformer substation comprehensive automation background, a power grid dispatching main station and various advanced application systems of the power grid dispatching main station.

Description

technical field [0001] The present invention relates to the technical field of time correction, in particular to a time correction method of a multi-data source voting mechanism based on the majority principle. Background technique [0002] The substation time synchronization system is used to unify the time of various data of all automation equipment and computer servers in the substation, so that it can work under a unified clock signal, and provide accurate, safe and reliable time for the operation of various equipment in the substation. Baseline to meet time synchronization requirements. Through the substation time synchronization system, all relevant data information is accurately applied in the substation comprehensive automation background, power grid dispatching master station and various advanced application systems. [0003] Such as figure 1 As shown, the existing substation timing system includes a main clock system, an expansion system and a timing terminal. Th...

Problems solved by technology

[0003] like figure 1 As shown, the existing substation timing system includes a main clock system, an expansion system and a timing terminal. The timing method is for the main clock system to use an expansion device to provide time service to the timing terminal. The timing method is broadcast and has no closed-loop monitoring and control functions. In daily operation, it often happens that some clocks of the main clock system, expansion device, and timing terminal are inconsistent, and it is difficult to find out during operation and maintenance. In addition, when the data information time scale of the same event is inconsistent, it cannot meet the needs of large power grids. The various advanced applications that run require
