| description | The invention provides a gas-steam combined cycle unit synchronous phasing test debugging method. Before first synchronous grid connection of a gas turbine generator, the gas turbine generator is usedto drive a gas turbine main transformer, a main transformer high-voltage side busbar and a steam turbine main transformer for stepping up from zero voltage; and then, synchronous loop check and phasing test are carried out on all synchronous points of the gas turbine generator and the steam turbine generator at one time. The debugging method has a simple operation process, synchronous loop checkand phasing test can be carried out on all synchronous points of the gas turbine generator and the steam turbine generator at one time, the debugging time is greatly shortened, the debugging efficiency is ensured, and the time of the start phase of the whole unit is controllable; the gas consumption of the gas turbine can be saved with many economic benefits; and voltage conduction check is carried out on primary devices s |
