The Research and Identify on Hydro Generator Rotor Windings Short-Circuit Fault

Abstract:

Hydro-generator unit is the most important energy conversion device in the hydropower, which is directly related to the safety and reliability and stable operation of the hydroelectric power plant. When the turbine generator rotor winding inter-turn short circuit occurs, the proposed method using load curve electromagnetic characteristics analysis, the use of before and after the failure to find the relative change in the excitation current failure rate as the identification method, the criterion may reflect the severity of the failure, perform theoretical calculations, and thus the inter-turbine generator rotor windings short circuit simulation, consistent with the conclusions of the theoretical analysis.
