Introduction

Extracting energy from the flow of rivers and waterways to generate electricity is a new type of power generation that uses river energy: This type of power generation does not require building The establishment of traditional hydropower dams has less impact on the environment: River energy resource assessment and characterization are important prerequisites for efficient development and utilization of river energy: carry: However, our country currently lacks relevant standards or technical specifications: Therefore, detailed standards need to be developed for river energy resource assessment in my country: and feature description to provide scientific methods and basis: This document aims to give a method for calculating the annual power generation of the river energy conversion device (array) to be deployed: In addition to containing relevant definitions, normative references, symbols and units, tables, appendices and other supporting material, the core content of this document is Contains the following main contents: ---Method to establish flow duration curve based on measured data or hydrodynamic numerical model; ---Method to establish flow velocity duration curve based on measured data or hydrodynamic numerical model; ---Method to calculate annual power generation based on flow velocity duration curve: This document will provide researchers working on river energy development and utilization with guidance on assessing river energy resources: River energy resource assessment and characterization

1 Scope

This document describes methods for determining theoretical river energy resources to ensure consistency and accuracy of resource assessments: This method is based on actual measurements Or numerical model or a combination of both to obtain the standard water flow velocity distribution, which will be used to evaluate the power generation performance of river energy resources: This document specifies feasible data collection methods and/or modeling techniques for river energy resource assessment, and a framework for reporting the results: This document is applicable to the stage of determining theoretical river energy resources in areas where river energy conversion devices (RECs) are deployed: This document does not apply to technical or physical resource assessments, assessment of the generation performance of river energy conversion devices, and environmental impact studies, assessments or Similar studies etc:
