Fault detection of Inter-turn Short-circuit in Rotor windings based on hybrid programming of MATLAB and VC++

Analyses the mechanism of detecting the Inter-turn short-circuit in Rotor winding fault with detecting coil, extracts the signal feature with wavelet transform algorithm. Hybrid programming of MATLAB and VC++ used in this paper directly embed MATLAB M document into the VC environment and make them run normally without MATLAB. The signal collecting, system frame constructing and interface drawing can be carried out by adopting VC++ graphical interface as the front-stage, while with MATLAB as the back-stage, the Inter-turn Short-circuit in Rotor windings fault can be judged through the data analysis and calculation. The results shows that the system has a good effect in practical application.
