​Determination of the electromagnetic forces of the synchronous electric generator for the asymmetric load condition by measurements ​

Forces acting on the stator teeth of the 400 kVA, 4 pole synchronous generator were analyzed for asymmetric electric load conditions. Measurement of the flux density was performed with the measuring coils installed on the stator teeth and calculations were done by finite element method. Measured data was processed to determine stator teeth radial forces through Maxwell stress tensor integration algorithm. Processed data was used for detection of asymmetric load condition. Parameters of the measuring coil sensors and their adequate position can be determined with finite element calculation before performing sensor installation on the machine.
