Standby fast resolving, and compare when opening SCD file, i.e., all IED equipment are carried out after comprehensive analysis, resettling IED and setting
The mode of standby list, improves the speed of SCD file parsing, the resolving of SCD file is effectively reduced, to CPU and internal memory
The occupation rate of resource is low, hardware resource is effectively discharged, and has a good application prospect.
Brief description of the drawings
Fig. 1 is the flow chart of the fast resolving method of the intelligent substation SCD file of the present invention.
Embodiment
Below in conjunction with Figure of description, the invention will be further described.Following examples are only used for clearly
Illustrate technical scheme, and can not be limited the scope of the invention with this.
The fast resolving method of the intelligent substation SCD file of the present invention, is searched by traveling through, sets up IED list of devices,
And offset of each IED equipment in the source file of SCD file is calculated, to the IED equipment fast resolvings chosen, and compare
When opening SCD file, i.e., all IED equipment are carried out after comprehensive analysis, resettle the mode of IED list of devices, improve
The speed of SCD file parsing, effectively reduces the resolving of SCD file, the occupation rate to CPU and memory source is low, makes hard
Part resource is effectively discharged, as shown in figure 1, following steps are specifically included,
Communication part (Communication) in step (1), the source file of importing SCD file, parsing source file, and
Traversal searches the beginning part of each IED equipment in source file, obtains IED device names, description information list, searches each
The keyword of IED equipment the beginning parts is IED or/IED, and the keyword of beginning location is IED, the keyword of end position
For/IED, and offset of each IED equipment in the source file of SCD file is calculated with starting position and end position；
Such as<IED name=" IT2202B " desc=" #2 main transformer 220kV side intelligent terminal B " type=" PCS-
222B " configVersion=" 1.00 "
Xmlns=" http://www.iec.ch/61850/2003/SCL">
