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 gridconnection process in the starting and downstream control phase of hydraulic turbine unit. It proposes corresponding solutions and improves the success rate of hydropower unit gridconnection.
