Abstract: Some faults of the watercooling system occurred in 1.5MW series wind driven generator set with higher frequency feedback and great influence, such as the electric heater burning out, the system pressure alarming, the aerocyst cracking and the abnormal electric control logic and others, were analyzed. These faults were analyzed; and according to the analysis result, several suggestions, such as to update the delivered manual of the watercooling system, to optimize the equipment subassemblies, to perfect the electrical control program of the master control system and others, were put forward, which provides certain reference for design optimization and daily maintenance of the watercooling system.
