The invention discloses an Electro Magnet Transients and Power Electronics (EMTPE) assisted compiling system for a power system, relates to an EMTPE assisted compiling system, and aims to solve the problems that the existing EMTPE software is low in operating speed and low in working efficiency. The EMTPE assisted compiling system for the power system comprises a data importing module for realizing an Excel importing function and further importing other.txt type file formats, a calculating module for enabling a calculating program to complete a calculating process of a current compiling file to enable a user to complete calculation with one key, a key word input module which is directly clicked to quickly add key words to the current cursor and directly select a plurality of rows, and is used for enabling the user to click an annotation button for one-step completion, a result extraction module for extracting useful information via clicking a button and generating a new file to enable the user to analyze the work in the next step conveniently, and an interface multi-label design module for enabling the user to perform switching among different documents. The EMTPE assisted compiling system for the power system is used in the field of power systems.
