Introduction

Under the strategic goal of "carbon peaking and carbon neutrality", the development of clean and low-carbon energy such as ocean energy can greatly reduce the level of CO2 emissions and help the Efforts to implement the national dual-carbon target strategy. In this regard, my country has established a standard system to support the investigation, evaluation, development and utilization of ocean energy. exist In this standard system, GB/T 41340 "Technical Specifications for Calculation of Power Generation of Ocean Energy Power Stations" is the basis for guiding the calculation of power generation of marine power stations in my country. basic standard. GB/T 41340 aims to establish the process, micro-site selection and calculation method of power generation of ocean energy power stations, which consists of two Partial composition. --- Part 1.Trend energy. The purpose is to establish the power generation calculation work suitable for the tidal current power station. --- Part 2.Wave energy. The purpose is to establish the calculation work of power generation suitable for wave power plants. The development of technical specifications for the calculation of power generation of ocean energy power stations and the standardization of calculation methods for ocean energy power stations are the key to large-scale development and utilization of ocean energy resources. important technical support.
