ABSTRACT

Railway Transport for many years has been one of INDIA’s fastest growing, environment friendly and the safest mode of transport.

It is safest mode today because of the efforts of the railway authorities of INDIA, one of which includes properly organised advanced signalling systems.

Uninterrupted Power Supply plays a significant role in the efficient working of Railway Signalling System. For this purpose, Integrated Power Supply (IPS) is being progressively installed on Indian Railways, due to its compact design and reliability. Failure of IPS may affect the punctuality and safety of trains.

Via this project I will be performing quality testing (hardware and logical) of IPS systems used by Indian Railways at CGL, Indore.

CHAPTER - 1

INTRODUCTION

Power supply system is the heart of signaling system. For a reliable signaling system installation, reliable power supply system is most important.

6

RE Area (Railway Electrified):

In AC electrified area, the main power is derived from the traction supply. In RE area the source of power supply to signaling system is through auxiliary transformer connected to OHE. This supply is very reliable but its occasional interruption/ low voltage cannot be ruled out leading to blank signals.

Non RE Area:In non-electrified area, the main supply is obtained from commercial power supply.The source of power supply is through a rural feeder, which is quite unreliable in respect of its availability and voltage. The battery backup is provided in all the DC circuit, which requires more maintenance. Due to frequent interruptions of supply, the signals are becoming blank till the starting of Diesel Generators.

7

To overcome these problems a comprehensive power supply scheme known as Integrated Power Supply system has been developed by RDSO.

The function of Integrated Power Supply system is to provide a stable and reliable AC and DC power supply to the Railway signalling installations against all AC mains variations or even interruptions. This is very essential for proper movement of trains. As the name indicates, it is designed and developed with a view to provide complete power solutions from single system to all signalling circuits. The IPS for Railway Signalling circuits shall be manufactured as per RDSO specification No. RDSO/SPN/165/2004, Amndt. 5.

RDSO approved Firms:At present following are the RDSO approved firms for supply and installation of IPS system on Indian Railways:

1. M/s Amara Raja Power Systems Pvt. Ltd., Tirupati.(A.P.)

2. M/s Statcon Power Controls Ltd., Noida (U.P.)3. M/s HBL Nife Power System Ltd., Hyderabad

CHAPTER - 2 LITERATURE OVERVIEW

This whole project is going to be performed under strict guidelines provided by Indian Railway Authorities and certain norms established by International Authorities. Some brief information about them are as follows :

1. SIGNAL DIRECTORATE RESEARCH, DESIGNS & STANDARDS ORGANISATION,LUCKNOW:

In India , For railway signaling systems there are certain standards which are to be kept in mind which are proposed and managed by above authority and is all provided in SPECIFICATION NO.- RDSO/SPN/165/2012.

2.EUROPEAN COMMITTEE FOR ELECTROTECHNICAL STANDARDIZATION (CENELEC): European standard EN-50129 was drafted and

approved by CENELEC in 2002 (which superseded ENV-50129) which generally included norms for the communication, signaling & processing systems. Now, standards given by above mentioned committees are basically used as guidelines for the

9

manufacturing & testing of Signaling Systems, employed presently in Indian Railways.

PROPOSED SCHEME

The IPS system basically consists of three major parts :

11

1. Float Rectifier Cum Boost Charger(FRBC) Panel:Shown in Red colour. This panel consists of

FRBC or SMR module Distribution/Supervisory control/Alarm (DSA)

unit.

2.A.C. Distribution Panel(ACDP):Shown in Blue colour. This panel consists of

Inverter. Ferro resonant based Automatic Voltage

Regulator (AVR) or Bypass CVT. Transformers.

3.D.C. Distribution Panel(DCDP):Shown in Purple Colour. This panel consists of

DC-DC Converters Common Digital Voltmeters for measurements.

The Scheme proposed for testing of IPS systems falls under the norms given by RDSO under SPECIFICATION NO.- RDSO/SPN/165/2012.

ANALYSIS COMPLETED TILL NOWFollowing will be the steps taken into account to cover the whole project efficiently and properly within specified time frame:

1. Collecting & Organizing the detailed information about the system which is to be tested:

(a)Which further involves keeping track of recent edification about the IPS.

2. Visiting the site (CGL, Indore) to physically acknowledge: (a) the various parts of hardware of IPS (which are to be tested).

(b) the various parameters which are to be tested.(c) the various instruments required to perform

testing safely.(d) the on-site availability of those instruments.

3. Completing a thorough report on the whole project.

WORK DONE TILL NOW:Following is a table briefly describing the various parameters (which are to be tested), device required for testing, and on-site availability of those devices:
