Problems solved by technology

However, when there are multiple faults in the distribution network, if the real-time section storage period is too long, there may be a problem that the saved real-time section data is far from the data when the fault actually occurred; if the real-time section storage period is too small, there will be a huge memory usage , the retrieval efficiency is low, and it is difficult to save a complete real-time section for dealing with multiple faults with a long time span

Embodiment 1

[0039] A real-time section preservation method for distribution network, such as figure 1 , including the following steps:

[0040] S1: Establish a section buffer area according to the network scale and computer memory size, and the section buffer area is used to save the real-time sections of the distribution network at different times;

[0041] S2: According to the life cycle of the distribution network fault, dynamically manage the real-time sections in the section buffer area, and only keep the valid real-time sections.

[0042] The section buffer area is a memory area including n consecutive blocks, wherein each block stores a real-time section at a moment.

[0043] Each block saves a real-time section at a moment, including the section time stamp, fault reference times and section data of the real-time section, where the section time stamp records the time corresponding to the section data; the fault reference times records the current associated fault of the section N...

Abstract

The invention discloses a real-time section storage method which comprises the following steps: S1, establishing a section cache region according to a network scale and a computer memory size, the section cache region being used for storing real-time sections of a power distribution network at different moments; and S2, according to the life cycle of the fault of the power distribution network, performing dynamic management on the real-time section in the section cache region, and only reserving an effective real-time section. Real-time sections of a power distribution network at equal time intervals are automatically cached, and a time mark and a fault reference counting attribute are recorded for each section; then, according to the life cycle of the fault occurring in the power distribution network in real time, the reference from a fault to a real-time cross section is established, the fault reference count of each real-time cross section is automatically maintained, invalid crosssections are automatically filtered according to the time scale and the fault reference count of each cross section, and the power distribution network real-time cross section storage with variable time scales, which is efficient and meets the requirements of multi-fault real-time processing, is realized.

Description

technical field [0001] The present invention relates to the field of power system automation, and more specifically, to a method, device and computer medium for real-time cross-section preservation of distribution networks. Background technique [0002] Faults in the distribution network are the main cause of power outages for users. At the same time, the distribution network has a large scale, complex wiring, and a wide coverage area. In different feeders and locations in the distribution network, the probability of multiple faults coexisting is relatively high. These faults may occur at the same time or at different times. , and the processing process of each fault needs to last for a period of time, especially for faults that occur on feeders that do not have closed-loop automatic control conditions, because the fault processing process requires some manual operations, and the duration of fault processing will be longer. When locating, isolating, and recovering each faul...
