GB/T 31163-2014 in English

1. Background and significance of standard formulation

GB/T 31163-2014 Solar Energy Resources Terminology is my country's first national standard for unified and standardized terminology in the field of solar energy resources. This standard was proposed by the China Meteorological Administration and aims to provide basic support for standardization work in the field of solar energy resources. With the rapid development of my country's renewable energy field, unified technical terms and definitions have become the key to industry communication and technological progress.

2. Comparison of the core framework of standards

3. Technical Background and Development

The background of the formulation of GB/T 31163—2014 is mainly due to the rapid development of solar energy resources in my country. In recent years, with the transformation of the global energy structure, solar energy, as an important renewable energy source, has made significant progress in technological innovation, equipment manufacturing and system integration. However, the problem of inconsistent terminology in the industry has become increasingly prominent, which has seriously restricted technical exchanges and standardization work.

3.1 Comparative Analysis at Home and Abroad

Compared with international standards (such as ISO 9488:1999), GB/T 31163—2014 has significant advantages in both terminology coverage and technical depth. However, there are still differences in some detailed definitions, such as:

• Calculation formula for solar altitude angle
• Specific application scenarios of air mass

4. Implementation suggestions

To ensure the effective implementation of GB/T 31163-2014, the following suggestions are put forward:

1. Strengthen the promotion and implementation of the standard: Organize industry training and technical exchange meetings to enhance practitioners' understanding and application capabilities of the standard.
2. Improve supporting documents: Formulate relevant technical specifications and implementation rules to provide support for the implementation of the standard.
3. Establish a feedback mechanism: Collect industry opinions and revise and improve the content of the standard in a timely manner.

4.1 Application Cases

During the construction of a solar power station, the accuracy and operability of the system design were significantly improved by citing the definition of direct normal radiation (DNI) in GB/T 31163-2014. Specifically, the inclination design of the collector was optimized and the system efficiency was improved through the precise calculation of the solar altitude angle and zenith angle.

5. Analysis of future technological evolution

With the in-depth application of artificial intelligence and big data technologies in the energy field, the subsequent revision of GB/T 31163-2014 should focus on the following directions:

• Supplementation of intelligent monitoring and prediction terms
• Improvement of relevant definitions of new energy storage technologies
• Standardized description of cross-domain synergy effects
