GB/T 42331-2023Directives for technology readiness assessment of tidal current energy generators (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents" drafting.

Introduction

The technical maturity assessment of tidal current energy generation devices is based on the background of vigorously promoting the development of tidal current energy resources and the construction of demonstration projects in my country.

To meet the needs of the development and technological innovation of the tidal current energy industry, make full use of the technology maturity theory, and combine the research and development and management of tidal current energy generation devices A set of evaluation methods and processes summed up from the company's experience to standardize the device development process, establish awareness of stage evaluation, and prevent new technology development risk, and promote the industrialization and engineering application of tidal current energy.

1 Scope

This document determines the level of technical maturity of tidal current energy generation devices, and describes the assessment dimensions, level conditions, stage assessment and assessment step.

This document is applicable to the technical maturity assessment work at each stage of research and development of tidal current energy generation devices.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.4 A scale used to measure the maturity of a technology

4 General principles

The technical maturity assessment of tidal current energy generation devices should follow the following principles.

a) The principle of timeliness. in combination with the characteristics and requirements of tidal current power generation technology at each stage of research and development, organize and carry out stage evaluation work, so as to Avoid the risks of transition.

b) Principle of objectivity. The evaluation criteria formulated based on the technical maturity level conditions fully reflect the generation and development of tidal current power generation technology. development and application, and reduce the influence of subjective factors.
