Research on Closed-loop Start-Up Process of Hydraulic Turbine Based on Adaptive Variable Parameters of Water Head

摘要

The large fluctuation range of the operating head of some hydropower stations has an impact on the arrangement of the starting mode. In order to suppress the influence of the water head on the start-up process, a closed-loop start-up simulation model of a hydro-generator unit is established in this paper, and variable parameter control based on head adaptation is adopted. By comparing the performance indexes of the closed-loop start-up process between the conventional PID control and the adaptive variable parameter control, it is shown that the adaptive variable parameter control based on the head has better dynamic adjustment performance.
