DESCRIPTION

BS IEC 62888-6:2019


This standard BS IEC 62888-6:2019 Railway applications. Energy measurement on board trains is classified in these ICS categories:
  • 45.060.01 Railway rolling stock in general
  • 45.060 Railway rolling stock

This part of IEC 62888 specifies the specific requirements for EMS to be used for benchmarking, daily energy consumption monitoring, technical research and development. This document provides the requirements for monitoring consumed energy on board in daily services in an easy way and the measured data are applicable for general purposes in industry such as energy management, energy saving, etc. However, this document is not applicable for billing purposes.

The practical purposes in industrial fields are, e.g.:

  1. monitoring daily energy consumption of vehicles;

  2. obtaining data on influential factors, such as operational commands and surrounding conditions, in order to analyse relations between operations and energy;

  3. energy management of power flow between vehicles and fixed installations;

  4. implementing investigation tests of research and development for vehicle systems;

  5. energy cost forecasting for analysing overall efficiency and consumption.

The requirements specified in this document supplement and/or amend the requirements specified in IEC 62888-1 to IEC 62888-5.

The energy measurement system (EMS) is categorized in 3 Levels as described in IEC 62888-1:2018, Table 1. This document applies to Level 2 and Level 3.

In this document unless levels are specially mentioned, both Level 2 and Level 3 apply. If a requirement applies only to one level between Level 2 and Level 3, this condition is clearly specified.

In the following clauses and subclauses square brackets, e.g. [IEC 62888-3:2018, 4.6.1] in the title indicate relevant clauses and subclauses of other parts. When lower subclauses of other parts are not listed, provisions of higher subclauses apply to the lower subclauses.

Table 1 – Levels of performance [IEC 62888-1:2018, Table 1]

Levels Description Notes
Level 1 Level for measuring energy consumption on board for applications like energy management, energy saving, billing and others. This is the only level applicable for billing
Level 2 Level for measuring energy consumption on board for applications like energy management, energy saving, benchmarking by suppliers or train operators and others. This level is not applicable for billing. Level 2 is applied when accuracy requirements need to be raised to ones equivalent to Level 1 by agreement by the Parties for international comparison or benchmarking purposes.
Level 3 Level for daily energy measurement, for instance: technical research and development. This level is not applicable for billing.
  • Based on users requests.

  • Both measuring performance and service conditions can be less severe than Level 1.

Power and energy are calculated based on voltage and current data acquired from existing sensors installed in converter systems, etc.
