A wave energy absorption and conversion device and a power generation system includes a floating body, a guiding shaft, a damping plate and a counteracting mechanism placed in a movement range of the damping plate. The guiding shaft is connected to the bottom of the floating body and passes through the center of the damping plate. The damping plate may slide on the guiding shaft. A counterforce generated by the counteracting mechanism is opposite to a natural moving direction of the damping plate, so that the damping plate can be kept in a relatively static state under a synergistic effect of the counteracting mechanism, and thereby, colliding of damping plate with constraint structures above and below can be prevented when floating body is moving up and down following waves. The power generation system includes the wave energy absorption and conversion device and a power generation system.
