Flexible self-adaptive high-low pressure lubricating oil system for gas turbine generator

The invention provides a flexible self-adaptive high-low pressure lubricating oil system for a gas turbine generator. The flexible self-adaptive high-low pressure lubricating oil system comprises a low-pressure lubricating oil system and a high-pressure lubricating oil system, the low-pressure lubricating oil system continuously provides lubricating oil for a bearing of the gas turbine generator, the high-pressure lubricating oil system provides jacking oil for the starting and stopping process of the gas turbine generator, and the high-pressure lubricating oil system and the low-pressure lubricating oil system share one lubricating oil tank; and the low-pressure lubricating oil system comprises a screw pump set, a shell-and-tube oil cooler, a duplex filter and a pressure transmitter which are arranged on the lubricating oil tank, and a high-level oil tank arranged outside the lubricating oil tank, the high-level oil tank can continuously supply lubricating oil to the bearing of the gas turbine generator when
