Scope

GB/T 36573-2018 is the English-translated version of 电力线路升压运行节约电力电量测量和验证技术规范.

GB/T 36573-2018 specifies how to measure and verify the electric energy saved when a power line is operated at a raised voltage.

It covers the main content of measurement and verification, the test plan and technical requirements, the calculation of the energy saved and the analysis and assessment of uncertainty, with normative annexes on calculating the savings and on measuring line load losses in the reporting period.

It defines voltage step-up operation, energy consumption parameters and measurement on the high-voltage side of the transformer. It applies to certifying the savings from step-up operation of AC power lines, and to energy-saving assessment before a step-up project is carried out.

It draws on GB/T 28750-2012, the general rules for energy measurement and verification, and on the IPMVP protocols. It was issued on 17 September 2018 and has applied since 1 April 2019.

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

1 Scope

This standard stipulates the measurement and verification of the power saved by the power line due to the increase of the operating voltage.

The law includes the main content of measurement and verification, test plans and technical requirements, calculation of power saving and uncertainty analysis.

This standard is applicable to the certification of AC power line boosting operation to save power, and is also applicable to energy saving before the implementation of line boosting project. Evaluation.

3 Terms and definitions

The following terms and definitions as defined in GB/T 28750-2012 apply to this document.

3.1 Voltage step-up operation of power line

After the power line is implemented, the power line is allowed to operate at a higher voltage level due to changes in physical facilities to improve the line. Technical means for conveying capacity and reducing operating losses.

Note: The power line may not implement the boosting retrofit project, and only increase the operating voltage to a value higher than the nominal voltage to continuously improve Power quality and reduce operating losses.

3.2 Energy consumption parameter

A variable or constant that affects the energy-saving effect of an energy management project activity.

3.3 High pressure side measurement

The electric energy metering device is installed on the high voltage side of the power transformer and measures the high voltage side parameters.
