Introduction

Energy efficiency is essential to meet the challenges of supporting energy policies, protecting the environment and conserving natural resources.

Energy efficiency, especially the standardization of overall energy efficiency of rail transit vehicles, has attracted great attention from the rail transit industry, and relevant standards are being gradually formulated.

The main contents include the definition and boundary of energy efficiency, influencing factors, test methods, etc. GB/T 44639 "Railway Transit Train the Electric Energy Measurement System aims to standardize the process of acquiring train electric energy data and ensure the reliability of the data. It is planned to consist of six parts.

--- Part 1: General. The purpose is to specify the system-level requirements of the energy measurement system and to implement one or more General requirements for equipment with multiple functions.

--- Part 2: Electric energy measurement. The purpose is to specify the requirements for electric energy measurement functions for measuring the electric energy consumed and regenerated by traction units, and Requirements for the voltage measurement function, current measurement function and energy calculation function that make up the energy measurement function.

--- Part 3: Data processing. The purpose is to specify the data processing system and ground data collection service in the electric energy measurement system requirements.

--- Part 4: Communications. The purpose is to specify the requirements for on-board data communication services and vehicle-to-ground communication services of the energy measurement system.

These communication services enable data to be transferred between functions within the energy measurement system, between the energy measurement system and other on-board units, and between data Handles exchanges between the system and ground servers.

--- Part 5: Conformance test. The purpose is to specify the consistency test of new energy measurement systems installed on traction units Arrangements, and conformance testing procedures for replacement of equipment and auxiliary components.

--- Part 6: Requirements other than billing. The purpose is to clarify the requirements for energy consumption benchmark testing, daily energy consumption monitoring, and technology research and development.

Able to measure the specific requirements of the system.

The functional structure, main sub-functions and data flow of the train energy measurement system (EMS) are shown in Figure 1.

1 Scope

This document specifies the specific requirements for energy measurement systems (EMS) used for energy benchmarking, routine energy consumption monitoring, and energy technology research and development.

Physical requirements.

This document provides a convenient way to monitor the on-board power consumption in daily train operation.

The data is applicable to industry sectors such as power management, energy conservation, etc. This document is not intended for billing purposes.

Note 1.EMS has practical uses in the following areas.

a) Daily power monitoring of vehicles;

b) Analyze the relationship between train operation and electric energy by acquiring data under influencing factors such as operating instructions and environmental conditions;

c) electrical energy management of power flows between the vehicle and ground units;

d) Perform investigative testing for train system development;

e) Predict electricity costs through overall electricity efficiency and consumption analysis.

The requirements specified in this document supplement and/or modify the requirements specified in GB/T 44639.1~GB/T 44639.5.

This document is applicable to level 2 and level 3 electrical energy measurement systems.

Note 2.Table 1 gives the performance level classification of electric energy measurement systems.

NOTE 3 Unless otherwise specified, the requirements in this document apply to both Level 2 and Level 3 energy measurement systems.

Table 1 Performance level

Level Description Notes Level 1 is suitable for on-board power measurement for power management, energy saving, billing, etc. This is the only level suitable for billing Level 2 Suitable for power management, energy saving, supplier or train operator benchmarking this level is not suitable for on-board power measurement in areas such as for international comparative measurements or benchmarking, etc., Level 2 EMS should the measurement accuracy is also very high.

Level 3

Suitable for daily power measurement, such as technology research and development. This level is not applicable for billing this rating is based on user needs, performance and usage conditions.

Level 1 EMS strict.
