The invention provides a three-planet-row dual-mode hybrid power transmission device. The three-planet-row dual-mode hybrid power transmission device comprises an engine input shaft, a generator G, a motor M, an output shaft, a planet gear assembly, a brake and a shell. The planetary gear assembly comprises a first planetary gear row, a second planetary gear row and a third planetary gear row which are in cooperative transmission, the third planetary gear row is in power output connection with the output shaft and in power input connection with the motor M, and the first planetary gear row is in power output connection with the generator G and in power input connection with the engine input shaft. The engine input shaft, the generator G, the motor M and the brake are in different states, so that the whole device can be in various working modes including a pure electric mode, an input shunt mode, a composite shunt mode and a reverse gear mode. The device can provide multiple modes to meet different requirements of low-speed driving and high-speed driving of the vehicle; and the control of each mode only needs to be combined with one control element, so that the control is simple.
