Emergency oil system for turbine and turbine system

The accident oil system comprises an accident generator and an accident oil pump, the accident generator is connected with the turbine so that the turbine can drive the accident generator to operate, and the accident generator is electrically connected with the accident oil pump so that power can be supplied to the accident oil pump when the turbine runs down. The emergency oil pump is used for driving the emergency oil pump to supply oil to the turbine, idle rotation of the turbine can be fully utilized, an emergency power source is omitted, energy is saved, production cost is saved, meanwhile, matched electrical equipment such as an inverter is omitted, the length of a used circuit can be reduced, equipment cost is further reduced, meanwhile, the equipment is simplified, and production efficiency is improved. And the complexity of equipment is reduced, the occupied space is saved, the pipe distribution difficulty is reduced, and the reliability of daily operation is improved. 本申请提供了一种透平机用事故油系统和透平机系统，包括事故发电机
