Introduction
GB/T 34910.4—2017 Standard Overview
GB/T 34910.4—2017 "Guidelines for Survey and Assessment of Marine Renewable Energy Resources Part 4: Ocean Current Energy" is a Chinese national standard that aims to regulate the survey, assessment and report writing of ocean current energy resources. This standard is applicable to the field of ocean current energy resource survey and assessment, and provides an important technical basis for the development of marine energy.
Background of Standard Formulation
With the growing global demand for renewable energy, ocean energy has attracted widespread attention as a clean and sustainable form of energy. As an important part of ocean energy, the resource survey and assessment of ocean current energy is the basic work for its development and utilization. The formulation of GB/T 34910.4—2017 fills the domestic standardization gap in the field of ocean current energy resource survey and assessment, and provides technical support for the scientific development and rational utilization of marine resources.
Comparison of Standard Frameworks
| Standard Dimensions | GB/T 34910.4—2017 | Comparison of International Standards |
|---|---|---|
| Survey Scope | Distribution, power density, and classification of technically exploitable energy resources of ocean currents. | In line with international standards (such as the IEC 62600 series), it focuses on global versatility and regional applicability. |
| Evaluation Method | Power density calculation model based on ocean current speed and direction (see formula in Section 5.2). | The method combines internationally accepted numerical simulation technology with measured data. |
| Technical indicators | Specify the observation elements, measurement accuracy and observation level requirements (see Table 1-3). | Align with international marine survey standards to ensure the scientificity and reliability of data. |
Implementation suggestions
1. Survey plan formulation
- Based on regional characteristics, give priority to selecting high-value blocks of current energy for survey.
- Reasonably design survey sections and stations to ensure the representativeness and scientificity of data.
- Combining multiple survey methods (such as fixed-point ship, anchor buoy, cruise, etc.) to improve data coverage.
2. Implementation of technical indicators
- Select observation instruments (such as ADCP, direct-reading current meter, etc.) in strict accordance with standard requirements to ensure measurement accuracy.
- Adjust the observation level according to the water depth and sea area characteristics to ensure the accuracy of the data.
- Standardize the data to meet the relevant requirements of GB/T 34910.1-2017.
3. Resource assessment and report writing
- Based on the survey data, comprehensively analyze key indicators such as ocean current power density and average power density.
- Determine the resource zoning level (rich area, relatively rich area, usable area, poor area) according to the classification standards in Table 3.
- The report writing must comply with the requirements of GB/T 34910.1-2017, and supplement the analysis and evaluation content of the survey results.
