Abstract

The invention relates to a method for assessing a tide energy resource through a numerical simulation of sea model. The technological steps are as follows: a target sea area is selected; sea chart splicing work of the target sea area is completed, and a high-precision terrain data product of the target sea area is manufactured; water depth terrain data measured through a field investigation are combined with satellite data, so that water depth terrain data of the target sea area are obtained; non- structural grid is performed on a calculation area of the target sea area, and the sea model is constructed; number value simulation calculation is performed with the sea model; a simulation calculation result and actually measured data are compared and verified; the energy flow density is calculated; the standing stock is calculated by selecting a section with a larger energy flow density; the developable tide energy power and the resource category are acquired according to the obtained standing stock; and an assessment result is displayed through a visualization technology. The method provides an important way for accurately assessing the tide energy level of the target sea area and solving the problem that the energy in coastal and sea island areas of our country is short.

Description

technical field [0001] The invention relates to ocean energy development technology, in particular to an evaluation method for tidal current energy resources. Background technique [0002] Ocean energy has the characteristics of renewability and non-pollution to the environment. It is an "inexhaustible" new energy source of strategic significance that needs to be developed and utilized urgently. my country has a vast sea area and abundant ocean energy resources. The development and utilization of ocean energy is an important way to solve the energy shortage in my country's coastal and island areas, and it is of great significance to promote the sustainable development of my country's economy. [0003] Tidal current energy is an important ocean energy resource with a wide range of distribution and great value for development and utilization. The reserve and distribution of ocean tidal current energy is an important prerequisite for the establishment of tidal current energy d...
