Method for quickly starting SCD file of intelligent substation

The invention relates to the technical field of power system automation, and discloses a method for quickly starting an intelligent substation SCD (Substation Configuration Description) file, which comprises the following steps of: when a client program is started, calculating an MD5 value of a model SCD file, comparing the calculated MD5 value with a stored MD5 value, and judging whether the calculated MD5 value is the same as the stored MD5 value or not; if yes, a binary file corresponding to the SCD file is directly analyzed; and if not, calling a dynamic library analysis model SCD file to generate a binary file and a new MD5 value, and carrying out analysis operation on the newly generated binary file. According to the technical scheme, once the corresponding binary file is generated, the medium data analysis can be quickly started, the device starting efficiency is greatly improved, the time consumption in the device starting process is reduced, and the field debugging and operation and maintenance effic
