Abstract

Abstract:

Taking #5 unit of a hydropower plant, it analyze the V/F limitation and over excitation signal during the starting process. It find out the main factor that affects the buildup and gridconnection process in the starting and downstream control phase of hydraulic turbine unit. It proposes corresponding solutions and improves the success rate of hydropower unit gridconnection.

Key words:

hydraulic turbine unit, V/F limitation, over excitation, grid connection, excitation regulator, governor
