Abstract

Abstract Tidal stream energy generation is a technology that harnesses the kinetic energy of tidal or ocean currents to produce electricity. Unlike traditional thermal and wind power generation, tidal stream energy generation relies on the natural movement of seawater for energy conversion. Due to the periodic and predictable nature of tides and currents, tidal stream energy generation offers high stability and reliability. This paper introduces the design of a micro-scale tidal generator with the power of 300W. An appropriate electromagnetic configuration was chosen, and the initial materials and electromagnetic structure of the generator were determined. Three-dimensional simulations were performed using finite element analysis. The design parameters of the prototype are reasonable, and all performance indicators meet the design requirements, confirming the feasibility of this generator for tidal stream energy generation.
