ABSTRACT

Railway Transport for many years has been one of INDIAsfastest 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.

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.

To overcome these problems a comprehensive powersupply 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.)

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 isall 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.


10/17

Now, standards given by above mentioned committees are

basically used as guidelines for the manufacturing &

testing of Signaling Systems, employed presently in

Indian Railways.

PROPOSED SCHEME


12/17

12

The IPS system basically consists of three major parts :

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.

PROPOSED METHODOLOGY

&

ANALYSIS COMPLETED TILL NOW

Following 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.
