The method and system for tide gate design and water flow control of tidal power plant which minimized the influence of bending angle of input water flow and which uniform the electricity output between each turbine generator and which keep the falling height by fast discharge of water

摘要

The present invention relates to a multi-flow tidal power generation method using a single flow generator, in a single flow type multi-flow power generation method for generating power for the ebb and flow of the tide using a single flow tidal generator operating in one direction, to solve the problem that each input floodgate cannot be in line with the opposing tidal generator, so that the pressure loss due to the bending of water flow toward the generator reduces the generation output, the problem that the inertia of the input water flow due to the angle mismatch between the input floodgate and the tidal generator causes a drift in the flow direction of the water flow, so that a difference in output between power generation waterwheels in the tidal generator is generated; and the problem that the output is lowered by the head drop reduction because the water flow discharged from the tidal generator cannot easily escape from a discharge water flow selection pond provided at a back end of the tidal generator to a floodgate connected to an inland sea or the open sea and is stagnant due to reduced momentum by expansion, when two input floodgates are connected from an input water flow selection pond provided at the front end of the tidal generator to the open sea and the island sea.
