The application discloses a
black start power supply
system and a running method for a
compressed air energy storage power station, and relates to the technical field of
compressed air energy storage. The
system comprises a compression subsystem, a
turbine power generation subsystem, a gas storage unit, a
molten salt heat storage subsystem, a high-temperature water heat storage subsystem and a self-driven
black start turbine power generation system. The self-driven
black start turbine power generation system utilizes high-pressure air and high-temperature water of the
power station as a power source, realizes full-
mechanical pressure self-driving through power-off
valve opening and self-force valve group, and can be automatically started when the whole
power station loses power. The high-pressure turbine and the low-pressure turbine coaxially drive a permanent
magnet generator to generate power, and the permanent
magnet generator preferentially supplies power to auxiliary machines of the power
station to complete the start of a main turbine unit, thereby abandoning a traditional battery type UPS, reducing initial investment and operation and maintenance costs, avoiding the risk of battery
thermal runaway, prolonging the service life of the equipment and being the same as the service life of the power
station, and fundamentally solving the problems of high cost of the existing black start power supply and short service life of the battery core.
