双Y移30°脉冲发电机制动系统研究

Study on braking system of double Y shift 30°pulse generator

通过对300MVA脉冲发电机采用不同制动电阻情况的计算,确定了制动电阻的冷却水温升。通过分析得出外接电阻越小其制动时间越短,在小电阻的情况下,其定、转子发热量更优。在采用0.15Ω电阻制动的情况下,300MVA脉冲发电机实际制动波形和计算得出波形基本一致,说明所提出的电气制动计算能够运用于电气制动设计。

By calculating for the cases of 300MVA pulse generator using the different braking resistance,capacity to cool the brake resistance was determined.By analyzing,it is obtained that the smaller the external series resistance,the braking time is shorter.In the case of small resistance,the stator and rotor heat of generator is better.In the case of 0.15Ωresistance braking,the actual braking waveform and calculated one of the 300MVA pulse generator are basically consistent,and the electrical braking calculation proposed in this paper can be used in the design of electrical braking design.
