Abstract

Abstract: In the Huadian International Zouxian Power Plant, the displayed temperature data of several measuring points in stator winding of 1 000 MW turbogenerator were abnormal. The elements installation and connection were inspected; the problematical elements were tracked and measured. Based on this, it was determined that there was electromagnetic interference and‘ground loop’ problem in temperature measure process. Aiming at the found problems, the temperature measurement of the turbogenerator stator winding was optimized and improved, so the accuracy of the temperature measurement of turbogenerator stator winding was ensured.

Key words: turbo-generator, stator winding, temperature, detection, treatment
