Abstract

PURPOSE: To enable the rotation number control of starting time to be controlled with stability and accuracy, in a cross compound type steam turbin having a turbin by-pass system.
CONSTITUTION: A turbin rotation number setting signal 21 is compared with the output signal from a rotation number detector 26 of the secondary axis B in a cross compound type steam turbin at an adder 23, and the result operated by an operator 24 is allowed to be conducted to an opening degree controller 30 of resteam stopping valve, thereby the signal controls the opening degree of the resteam stopping valve 6. The output of the controller 30 is conducted to an opening degree controlling circuit 25 of a main steam stopping valve 2 via a rate operator 31 and an adder 32. On the other hand, the outputs of each rotation number detectors 26,22 of the secondary axis B and the primary axis A are compared by an adder 27. When the resteam stopping valve 6 may be opened, both axes B,A are accelerated by means of inflowing to a middle pressure turbin 8 and low pressure tubrins 9a, 9b by steam, and when the main steam stopping valve 2 may be opened, only the axis A is accelerated.
