bine-generator unit startup test and test of the unit with rated
load running for 72 hours continuously shall be carried out.
1 Turbine-generator unit startup tests. The procedure of
the startup test shall be compiled by the commissioning c o m ma nd
group and approved by the startup acceptance committee, and in­
cludes：
1) Examine and test the diversion system, turbine and
governor, generator and excitation system, oil-water-
gas system and generator cooling system, electrical e-
quipment，control protection devices, and measuring
meters.
2) Examine and test diversion facilities and equipment
both during and after water filling.
3) Examine and test the first time startup of the turbine-
generator unit and no-load operation.
4) Examine and test the turbine-generator unit when con­
necting to the grid and operation with loads.
5) Test turbine-generator unit load rejection.
2 Tests of the turbine-generator unit with rated load run­
ning for 72 hours continuously. Before the test, the committee
shall listen to a brief report by the commissioning c o mm an d
group and the supervisor, so as to make a decision on whether
the unit can run 72 hours with rated load continuously. If the
actual load less than the rated output of the unit or the output
less than the rated one due to some special reasons, the commit­
tee m a y determine the m a x i m u m test load of the unit according to
actual conditions.
3 If the unit running for 72 hours with loads is normal,
then turbine-generator startup commissioning is deemed comple­
ted. The commissioning c o m m a n d group shall report the c o m ­
