MATLAB-based analytical processing on measured air gap data of hydroelectric generator is discussed. Firstly, the air gap bar graphs are achieved by identifying the number of magnetic poles and calculating the minimal values, including cycle distinguishing, burr elimination and correction, cycle joining and extremum judgment. Secondly, the roundness of rotor and stator of hydroelectric generator are assessed, including the fitting of least square circle and the acquisition of roundness feature parameters. The results show that the MATLAB can quickly and effectively process measured air gap data of hydroelectric generator, and the MATLAB-based analytical processing on measured air gap data of hydroelectric generator is practical.
