The invention relates to a series-parallel hybrid power system for a tuna longline boat. The series-parallel hybrid power system comprises a diesel engine, a power distributor, a storage battery, a motor, a fuzzy controller, a gear box and a propeller. The series-parallel hybrid power system has the advantages that different power requirements of the full-speed running working condition, the rope throwing working condition, the rope hoisting working condition can be met through the fuzzy controller by reasonably selecting and distributing a diesel engine power system and a motor power system, the diesel engine can stably work relatively efficiently, the fuel economy is improved, and pollution is lowered; the motor is high in torque reaction speed and small in fluctuation, a wider speed adjusting range is achieved, larger torque can be output at the low speed of the motor, the motor has larger overload coefficients and is high in working efficiency and good in stability, and the maneuvering characteristics of the fishing work is improved; a magnetic coupling is adopted to serve as a transmission mechanism, the transmission performance of the hybrid power system is improved, and the power consumption loss is lowered.
