Problems solved by technology

However, for the remote signaling state, especially the switch position state that needs to be used in data analysis, the current system does not store historical sections
This makes it impossible for analysts to quickly judge the opening and closing status of switchgear at that time when analyzing accident events or analyzing the topological relationship of equipment after the event. They can only query historical items and combine manual analysis to judge the equipment status at that time. This analysis method consumes manpower larger, less efficient

Embodiment 1

[0022] Such as figure 1 As shown, a method for generating equipment status sections based on historical events includes the following steps:

[0023] 1) Confirm the switchgear that needs to generate the equipment status section, and find the name of the switchgear; for example, in the analysis, it is necessary to obtain the remote signal section of all 220kV substation high-level switches, and it is necessary to find all 220kV substation high-level switches in the system in the dispatching automation system For example, the 2201 switch of Foshan Station is named FSZ.2201DL, and the device name of the 2202 switch system of Fenjiang Station is FJZ.2202DL. Obtain the name of the device that needs to generate the remote signaling section.

[0024] 2) According to the name of the equipment and the time period when the section needs to be generated, obtain the switch displacement historical items; for example, if it is necessary to generate the switch remote signal section for two ...

Abstract

The invention provides a device state section generating method based on historical items. According to the method, inquiry and analysis are carried out on acquisition of a device name and device state change historical items in the time period, the contrast before and after the time is converted into a size comparison problem of a time stamp, and a device state section of every 15 minutes in thetime period is generated. The section can facilitate rapid acquisition of the state of a certain historical time node device by operation and maintenance personnel, the problems that the efficiency islow and the workload is large due to the fact that the state of the historical section device is only acquired through inquiry and manual analysis of the historical items in the prior art are solved.The cross section generation also provides data support for a power grid analysis function combining a device measurement section.

Description

technical field [0001] The invention relates to the field of methods for generating remote signaling sections of power grid equipment, and more specifically, to a method for generating equipment status sections based on historical events. Background technique [0002] With the continuous deepening and development of the application of power grid dispatching automation system, topology analysis has become a more common application in dispatching automation application. Topology analysis in dispatching automation system can only be carried out for real-time or certain historical sections. For telemetry data, the system every Record a section in 15 minutes, which is convenient for operation and maintenance personnel to query historical curves. However, for the remote signaling status, especially the switch position status needed for data analysis, the current system does not store historical sections. This makes it impossible for analysts to quickly judge the opening and closi...
