Abstract
A steam turbine test facilityincludes a test steam turbinewhich simulates the behavior of a real steam turbinesincluded in the steam turbine plant, and a motor-generatorconnected to the test steam turbine. A control unitincluded in the motor-generatorcontrols the motor-generatorto change the rotational speed of the test steam turbinebased on an arbitrarily set speed change pattern. The speed change pattern is set such that the test steam turbinein the load disconnection state simulates a time-profile of the rotational speed of the steam turbineswith the load disconnected.
