A horizontal shaft tide turbine power generation device storing energy by means of a flywheel is characterized in that a turbine shaft is accelerated by means of a transmission, the flywheel is driven by an electromagnetic coupler to rotate, and the flywheel drives a generator to operate. When first starting is carried out, the flywheel needs to store energy, loads are disconnected by the generator at the moment, and the flywheel is continuously accelerated. When the flywheel reaches a designed rotating speed, the generator starts to generate electricity; when power of the turbine shaft is higher than power of the generator, the flywheel continues to store kinetic energy, and the rotating speed of the flywheel is increased; when the power of the turbine shaft is lower than the power of the generator, the flywheel releases the kinetic energy, and the rotating speed of the flywheel is decreased. When the tide speed is low, the turbine brakes and is disconnected with the flywheel, and the flywheel continues to drive the generator to operate by means of the stored kinetic energy. A turning device is adopted to maintain the obverse side of the turbine to always face towards a coming tide, and therefore the constant rotating direction of the turbine shaft is guaranteed. When a new tide circulation is started, the tide speed reaches to a starting speed, the flywheel can drive the turbine to be started through the electromagnetic coupler, and the problem that the turbine cannot be normally started is eliminated.
