Abstract：This paper introduced the realization theory and application situation of intelligent load sharing about SCR power cabinet in generator excitation system, cited the problems exist in intelligent load sharing from the angle of field operation, and analyzed the following points, intelligent load sharing reduced overall reliability of excitation equipment, impacted the phase commutation and transient process on SCR, made some components bear instantaneous impact and more loss, accelerated the aging of device, and reduced the service life. The final conclusion was that natural load sharing is the correct way to ensure load sharing. In addition, the paper introduced several factors which affect the effect of load sharing and disposal measures, and provided a reference for solving on-site problems.
