Full Description

Scope

This guide specifies the requirements and testing methods for a stationary energy feedback system to be used in trackside installations for a dc electrified railway power supply network. This system can harvest electric energy from the dc power supply network and feed the energy back to the ac power supply network. This guide covers terms and definitions, rating values, performance requirements, and test requirements. Performance requirements include efficiency, temperature, lifetime, control and protection, electromagnetic compatibility (EMC), and mechanical characteristics. Test requirements will cover methods and criteria for type test, routine test, and commissioning test. However, the systems with the following functions are not included in this guide: - Resistive consumption of regenerated power - Energy storage system

Purpose

The purpose of this guide is to achieve the following objectives:- Definition of the energy feedback system:- Terms and definitions for the energy feedback system- Rated value- Typical topologies- Definition of the performance for the energy feedback system:- General requirements such as rating, efficiency, temperature and lifetime- Control and protection requirements, include inverter/converter/static var generator/active power filter control, short circuit protection, earth-fault protection, overload protection- Electromagnetic compatibility (EMC)

Abstract

New IEEE Standard - Active.In the dc electric railways, when a train regenerates power, usually the power has to be consumed within the dc network because the dc traction power systems are often not reversible. Several technologies improve receptivity: energy consumption, energy feedback, and energy storage. Solution selection depends on the application. The energy feedback systems (EFSs) convert energy to ac power system as system dc voltage rises. Engineers are helped by this guide to decide where these EFSs can provide the greatest benefits, determine which design solutions will have the maximum effectiveness, and evaluate the costs and benefits of developing new EFS projects.
