The application provides a converter valve area short-circuit fault positioning method, device, equipment and medium, the method comprises the following steps: dividing the converter valve fault into eight typical valve area short-circuit faults; RTDS simulation analysis, according to the different converter protection action results, dividing into three types of protection actions, giving the typical fault characteristic quantity of the valve difference protection action for positioning the valve area fault and the eight typical valve area short-circuit quick criterion; according to whether the actual converter protection action occurs in the rectifying station or the inverting station, confirming the valve area short-circuit fault occurring station; according to the converter protection action event of the monitoring background, confirming the converter protection action type and the valve area fault converter bridge; calling the built-in fault recording of the DC control protection, analyzing the converter protection action waveform, analyzing the fault characteristics of the current waveform of the valve side of the converter bridge and the outlet current waveform of the DC side, positioning the valve area short-circuit fault point according to the typical fault characteristic quantity of the valve difference protection action and the eight typical valve area short-circuit quick criterion; and has the advantages of fast positioning speed and simple analysis method.

The invention belongs to the technical field of aircraft overall design technology flight load, and relates to a vector similarity-based pressure test dead pixel data correction method. In the wind tunnel pressure measurement test process, according to the pressure distribution of adjacent points around the pressure measurement defective pixel and the profile, the working condition most similar to the test data in the reference data can be searched based on the existing reference data, and the pressure data of the position where the pressure measurement defective pixel is located can be automatically predicted and restored. Compared with a manual restoration mode, the method has the advantages that the data analysis and processing efficiency is greatly improved, the manual workload is reduced, and the problem that the data result is unstable due to the fact that the proportion of self experience in manual restoration is too large is solved; and compared with a linear interpolation mode, the reasonability and accuracy of data restoration are improved. Therefore, the method improves the rapid data processing capability in the pressure measurement wind tunnel test process.
