The invention discloses a three-planetary-gear-set two-gear-variable hybrid power system which comprises an engine, a first planetary gear set, a second planetary gear set, a third planetary gear set and a fourth planetary gear set. The clutch is connected with the output shaft of the engine; the first planet row comprises a first outer gear ring, a first planet carrier and a first sun gear. The first planet row is connected with the clutch; the first motor is provided with a motor output shaft; and the second planet row comprises a second outer gear ring, a second planet carrier, a second sun gear and a locking mechanism, and the second planet row is connected with the second motor and the first planet row and is in transmission connection with a differential mechanism. The second motor is provided with a motor output shaft; and the third planet row comprises a third outer gear ring, a third planet carrier and a third sun gear. And the third planet row is connected with the second motor and is in transmission connection with the differential mechanism and the first planet row. And a locking mechanism is arranged at the part in transmission connection with the first planet row. The hybrid power system has the advantages of being compact in structure, fast in mode switching, capable of achieving two-gear switching, good in fuel economy and energy-saving effect and the like.
