STEAM TURBINE TEST FACILITY, LOW-LOAD TEST METHOD, AND LOAD DUMP TEST METHOD

摘要

It is an object of the present invention to provide a steam turbine test facility including a test steam turbine, in which the behavior of an actual steam turbine can be precisely simulated and the efficiency of performance test can be improved. A steam turbine test facility 1 includes a test steam turbine 2 which simulates the behavior of a real steam turbines 11 included in the steam turbine plant 10, and a motor-generator 4 connected to the test steam turbine 2. A control unit 5 included in the motor-generator 4 controls the motor-generator 4 to change the rotational speed of the test steam turbine 2 based on an arbitrarily set speed change pattern. The speed change pattern is set such that the test steam turbine 2 in the load disconnection state simulates a time-profile of the rotational speed of the steam turbines 11 with the load disconnected.
