Introduction
GB/T 34910.3—2017 Standard Overview
National Standard of the People's Republic of China GB/T 34910.3—2017 "Guidelines for Survey and Assessment of Marine Renewable Energy Resources Part 3: Wave Energy" is the first standardized document in my country for the survey and assessment of wave energy resources, providing a scientific basis and technical support for the development of marine renewable energy.
Comparison of standard frameworks
| Chapters | Main points | Key words |
|---|---|---|
| 4 Wave energy resource survey | Survey content and methods, including observation elements, technical indicators and station selection | Wave height, Wave period, Wave direction |
| 5 Wave numerical simulation | Numerical calculation methods, model selection and verification requirements | Wave model, Wave height frequency spectrum, Wave direction |
| 6>Group velocity calculation | ||
| 6 Wave Energy Resource Assessment | Resource parameter calculation, assessment steps and result analysis | Energy flux density, Effective wave time, Seasonal variation index |
Core terms and application cases
1. Wave Energy Flux
Definition:The energy flux passing through a unit width section along the wave propagation direction.
Application:In the development of marine energy, wave energy flux density is the core indicator for assessing the energy potential of the sea area. For example, in deep water conditions, the following formula (13) can be used to quickly estimate: $$ P_{\mathrm{w}} = {\frac{\rho g^{2}}{64\pi}H_{\mathrm{s}}^{2}T_{\mathrm{e}}} $$
Technology evolution and standardization background
With the increasing global demand for renewable energy, ocean energy, especially wave energy, has attracted much attention due to its wide distribution and abundant reserves. The formulation of GB/T 34910.3—2017 fills the gap in domestic standards in this field and provides technical support for scientific planning and sustainable development.
Implementation suggestions
- Data collection:Preferably use the third-generation wave model combined with field observations to ensure the accuracy and representativeness of the data.
- Regional applicability: Optimize survey stations and simulation grid resolution according to the characteristics of different sea areas.
- Technical verification: Calibrate the numerical model through long-term measured data to improve the reliability of the assessment results.
