Problems solved by technology

Since each device object allocates memory once, and the length of memory allocated each time is a small memory of tens to one hundred bytes, devices within a certain range (such as the whole province) will generate tens of millions of small objects memory allocat

Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0046] The power grid topology memory data processing method provided by this application can be applied to such as figure 1 shown in the application environment. The user operates the device 102. After the device 102 is started, it obtains the grid topology memory data, divides the grid topology memory data into relatively independent and topologically connected data partitions, converts the geographic information objects in the data partitions into analysis objects, and obtains the data partition correspondence. The analysis objects corresponding to the data partition a...

Abstract

The invention relates to a power grid topology memory data processing method and system, computer equipment and a storage medium. The method comprises the steps that 1 power grid topology memory dataare divided into relatively independent and topologically connected data partitions; converting a geographic information object in a data partition into an analysis object; an analysis object corresponding to the data partition is acquired; and the analysis object corresponding to the data partition is stored in a paging manner with a fixed length. The length of each analysis object in the memoryis fixed. Efficient memory allocation can be carried out in a paging mode, and memory fragments are avoided. When access is needed, subscripts representing mutual reference between the analysis objects after paging storage are obtained. The analysis objects subjected to paging storage are accessed through the subscripts, and rapid and efficient access can be achieved.

Description

technical field [0001] The present application relates to the technical field of power grids, in particular to a grid topology memory data processing method, device, computer equipment and storage medium. Background technique [0002] Business systems such as production and planning supported by the GIS platform need to perform analog topology analysis operations, such as analyzing the power outage plan caused by pulling together several switches based on the current switch operating status or the annual normal operating status. This needs to provide real-time, normal and research topology analysis support on the GIS application server. The real-time state corresponds to the current operating state of the power grid, and the switch state is updated in time with SCADA remote signaling and dispatching manual settings. The normal state corresponds to the annual (or monthly) operation mode, and the switch state usually does not change. The research state is based on the real-tim...
