Beschreibung
Zusammenfassung:	The invention discloses a load reduction control method, system and equipment for a double-shaft steam turbine generator unit and a medium, which can realize automatic synchronous quick load reduction of a boiler and residual steam turbines under the accident working conditions of tripping of a main auxiliary engine of the boiler, or respective faults of a high-position steam turbine, a low-position steam turbine and a generator of the high-position steam turbine and the low-position steam turbine, or separation of a main transformer and a bus of the unit. Through cooperative control of a bypass system, main process parameters of a unit can be stably reduced to a safe operation range corresponding to a target load in a short time, abnormal shutdown of the unit is avoided, in addition, isolated network operation can be realized under the off-network condition, and the condition of rapid re-grid connection is provided, so that the efficiency is improved. The steam turbine generator unit with the high-low-positi
