Study of Starting Process of Pumped Storage Machines by Static Frequency Converter
For the pumped storage macbines started by static frequency converter (SFC), the mathematical model of multi circuits is established considering actual arrangement of the dam per bars based on the multi-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 naturajly 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 lO seconds, so it is necessary to control the excitation current by the excitation section in the inverter.
