Apparatus for compiling script

An apparatus employed in a supervisory control and data acquisition (SCADA) system for compiling scripts, comprising:

• a database configured to store, via a processor and a memory, power data acquired from a power system and an index of the power data;
• a script generating unit configured to generate, via the processor, a script based on the power data stored in the database;
• a determining unit configured to determine, via the processor, whether the index of the power data stored in the database has been changed;
• and
• a compiling unit configured to compile, via the processor, the script generated in the script generating unit based on the determination result,
• wherein the database is further configured to store version information corresponding to the power data and the index of the power data,
• wherein the version information is set according to whether the power data and the index of the power data have been changed,
• wherein the script generating unit generates a script based on the power data corresponding to the version information,
• wherein, if an error occurs in the script, the script generating unit recovers a previous script stored in the database corresponding, according to the version information, to a previous version of the script, and
• wherein, if it is determined that the index of the power data has been changed, the compiling unit compiles only a part of an already-generated script that is generated based on the power data with the changed index by referring to the changed index of the power data.
