[0031] S2, since the recording wave file is generated later, the system determines whether a new recording wave file is generated according to a current SOE event, and if not, continues to wait, and if so, saves and parses the recording wave file through the recording wave file saving and parsing service unit;

[0032] S3, the recording wave file saving and parsing service unit saves the new recording wave file to a specific folder of the system, so as to be used for historical query by a user later, and parses power regulation process data such as power and frequency from the recording wave file according to requirements, and transmits the data to the fast power regulation data analysis service;

[0033] S4, the power regulation data analysis service unit analyzes important index data of a current power regulation process of the device according to time, corresponding power and frequency data of SOE event occurrence, in combination with power regulation process data of the recording wave file, including starting frequency, control response time, control regulation time, integrated electric quantity, etc., and stores the index data in the database correspondingly.​
