SOE information management method and storage device thereof

Abstract

The invention discloses an SOE information management method and a storage device thereof. The method comprises the steps of storing SOE information in a cyclic data storage area, the storage contentof each piece of SOE information comprises time scale information and a flipping character, the flipping character represents the number of times that the cyclic data storage area is covered, and thelength of the space occupied by the flipping character is smaller than the length of the space occupied by the time scale information; and traversing the SOE information according to an address sequence from a starting address to an ending address of the cyclic data storage area, searching different flipping symbols, and determining the SOE information stored at the earliest time. The embodiment of the invention at least has the following beneficial effects: the calculation amount and the space occupation during comparison are reduced, the CPU processing time is reduced, and the processing efficiency is improved, so that the safe and effective operation of the low-performance power grid equipment is ensured.

Description

technical field [0001] The invention relates to the field of intelligent power distribution, in particular to a method for managing SOE information and a storage device thereof. Background technique [0002] SOE is the sequence of events record, the abbreviation of Sequence Of Event, which is mainly used to record the accurate time of multiple switch input signal displacements when an accident occurs, so as to distinguish the sequence of multiple displacements. The switch value input displacement event information. Each piece of SOE information is composed of 8 bytes, which are 1-byte binary input variable position information and 7-byte CP56time2a time information. [0003] The existing method for obtaining the earliest stored SOE information is to sort the CP56time2a time stamps of all data according to the SOE data format after reading all the data. With the increase of equipment commissioning time, there are more and more SOE records, even reaching hundreds or even tho...

Problems solved by technology

With the increase of equipment commissioning time, there are more and more SOE records, even reaching hundreds or thousands. The search efficiency will become lower and lower, which will cause a sharp increase in the amount of calculations for distribution network equipment based on low-performance embedded platforms, and even affect data sampling and fault judgment, causing malfunction or refusal to operate, affecting the reliable operation of the power grid
