This paper studies the steady-state and transient heat conduction characteristics of the stator windings of a bulb tubular turbine generator in through-flow operation,and analyzes the relationship between output power and winding temperature.Based on historical data,a mathematical model is established between the temperature at the end of the winding and the temperature in the middle of the winding.Through the establishment of a temperature testing platform for bulb tubular turbine generators in through-flow operation,the theoretical analysis is validated.This research lays a theoretical foundation for the temperature monitoring of stator windings in bulb tubular turbine generators in through-flow operation.
