Power plant water system intelligent linkage control method and system based on fault early warning

The invention discloses a power plant water system intelligent linkage control method and system based on fault early warning, and the method comprises the steps: 1), transmitting early warning information when fault equipment exists; 2) maintaining the current operation of the fault equipment, reducing the power to operate or switching the equipment to operate; 3) judging whether the internal fault of the system where the fault equipment is located is self-healed or not, when the internal fault of the system where the fault equipment is located cannot be self-healed, sending a linkage instruction to an upstream system and a downstream system associated with the system where the fault equipment is located, taking autonomous control measures on the fault equipment, and selecting a proper equipment operation mode; 4) after the autonomous control of the faulty equipment is finished, judging whether the fault is eliminated, and when the fault is eliminated, recovering the original operation mode of the faulty equ
