Study of Process of Starting Pumped Storage Machines by Static Frequency Converter With Field Current Controlled
For the pumped storage machines started by static frequency converter (SFC), the mathematical model of mujti circuits is established considering actual arrangement of the damper bars based on the m ulti-circuits theory of the electrical machines. On the basis of this mathematical model the process of static frequency converter starting were analyzed on simulation and analysis of the naturally operational phase. Meanwhile the rules of current, torque, rotational speed were given and several factors influencing starting were analyzed as well. The results show that, then the excitation current will rise quickly with the excitation control added, which can reach 4 times the rated value in 10 seconds, so it is necessary to control the excitation current by the excitation section in the inverter.
