GB/T 30256-2023Technical requirements of measurement and verification of energy savings—Electric motor system (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" to be drafted.

This document replaces GB/T 30256-2013 "Technical Requirements for Energy Saving Measurement and Verification Pump Liquid Delivery System" and GB/T 30257-2013 "Technical Requirements for Energy Saving Measurement and Verification Ventilation Fan System". Compatible with GB/T 30256-2013 and GB/T 30257-2013 In addition to structural adjustments and editorial changes, the main technical changes are as follows:

---Changed the scope of application and added the general air compressor system (see Chapter 1, GB/T 30256-2013 and GB/T 30257- Chapter 1 of 2013);

--- Added the term "motor system" and its definition (see 3.1);

--- Added basic requirements for sampling calculation, uncertainty analysis, and interaction effects (see 5.5, 5.7, 5.8);

--- Increased the main energy consumption factors of motor systems such as fan systems, pump liquid delivery systems, and air compressor systems (see 6.1.1);

---Changed the calculation method of "base period energy consumption-influencing factors" model method and direct comparison method, applicable to single or multiple influencing factors factors or working conditions (see 6.1 and 6.2, 5.1 and 5.2 of GB/T 30256-2013, 5.1 and 5.1 of GB/T 30257-2013 5.2);

--- Deleted the simulation software method (see 5.3 of GB/T 30256-2013 and 5.3 of GB/T 30257-2013);

--- Increased carbon dioxide emission reduction calculation method (see Chapter 7).

1 Scope

This document stipulates the project boundary division and energy consumption statistical scope and basic requirements for the energy saving measurement and verification of the motor system energy saving renovation project.

It describes the measurement and verification methods, and the calculation method of carbon dioxide emission reduction.

This document is applicable to motor systems such as AC electric drive fan systems, pump liquid delivery systems, and general air compressor systems.

Measurement and verification of energy savings and calculation of carbon dioxide emission reductions for system energy-saving renovation projects. Motor systems such as machine tools driven by motors, belt conveyors, and Other newly-created projects refer to it.
