Abstract

The invention provides a timekeeping method and system for a power distribution automation terminal. The invention reads the time of the RTC chip from the power distribution terminal and synchronizes it to the system clock at the time when the second of the RTC chip changes. The system clock and the RTC clock are synchronized, and the power-off time of the power distribution terminal is recorded, and the time error caused by the precision of the RTC chip is adjusted and compensated during the power-off period, so as to realize the punctuality of the power distribution automation terminal. The invention does not add additional hardware, and uses software to correct the punctuality error, effectively saving costs; and the invention fully meets the requirements of the State Grid Corporation of China for the technical specifications of the distribution automation terminal, and significantly improves the power distribution automation terminal. Punctual precision.

Description

technical field [0001] The invention relates to the technical field of distribution automation, in particular to a method and system for keeping time of a distribution automation terminal. Background technique [0002] With economic development and social progress, the scale of distribution network is getting larger and larger, and the number of distribution automation terminals in operation is growing explosively. The distribution automation terminal is responsible for the collection and monitoring of on-site information such as the current, voltage, and switch status of primary equipment in the distribution network. The distribution network is a time-related system. Only when the accurate collection time is recorded can the on-site data have analytical significance and value. [0003] Distribution automation terminals generally use clock chips and external batteries to realize clock keeping. The "Technical Specifications for Distribution Automation Terminals" issued by th...
