Research on Negative Sequence Capacity of DongFang 600MW Turbogenerator

It is calculated negative sequence eddy field of 600MW turbine generator.With negative sequence capacity test data of 200MW turbine generator,it adopts method of combined calculation with analogy analysis,the coefficient of heat dissipation and the highest temperature are educed,accordingly the 600MW turbine generator negative sequence capacity is calculated,it is proved that this research is very useful for generator design and safe operation.
