Abstract

The invention relates to a time scale processing method and system based on a multi-framework distribution automation terminal, and belongs to the technical field of distribution automation systems. The time scale accuracy of the distribution automation terminal is realized by using multiple frameworks, and the method comprises the following steps: S1, reading a remote signaling signal according to signal input, and recording the time scale at the moment; S2, storing the signals and the time marks to a specified register according to a signal acquisition sequence; S3, updating the writing pointer while storing the signal and the time scale in the register; S4, initializing a time scale and a synchronous clock; S5, obtaining signals and time scale data in the register regularly; S6, acquiring response data according to the position of the writing pointer; S7, analyzing the acquired data signal, and converting a time scale into a timestamp; and S8, judging whether the signal is abnormalor not, overturning, and reporting an event. According to the invention, more real-time data acquisition and time scale recording are carried out by using multiple frameworks, so that the accuracy oftime scale and acquisition is improved, and the system response is more accurate.

Description

technical field [0001] The invention belongs to the technical field of distribution automation systems, and relates to a time scale processing method and system based on a multi-framework distribution automation terminal. Background technique [0002] With the rapid development of my country's social economy and the increasing demand for electricity, the power grid has become an important pillar of national economic development. The power grid is an important infrastructure related to national energy security and economic lifeline, and has a huge impact on social production and daily life. Among them, the safe power supply of the power grid is an important part of the national power industry and an important measure to ensure normal social order. Therefore, the intelligent power distribution automation terminal has become an irreplaceable link in the protection of power consumption. [0003] In the power system, new information and communication technologies are continuousl...
