A traction substation, traction current converter plant or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or trolleybuses with traction current.
Conventional power supply of 25 kV 50 Hz railway systems was carried out using two-phase transformers in the past. Recently static frequency converters for traction power supply substations have. A substation is a part of an electrical generation, transmission, and distribution system.
Substations transform voltage from high to low, or the reverse, or perform any of several other important functions.
Between the generating station and consumer, electric power may flow through several substations at different voltage levels. Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea.
Traction substations are used to convert electrical power as supplied by the power utility (or rail operators own network) to a form suitable for providing power to a rail system (via third rail or overhead line).
Allows the reader to deepen their understanding of various technologies for both fixed power supply installations of railway systems and for railway rolling stock This book explores the electric railway systems that play a crucial role in the mitigation of congestion and pollution caused by road traffic.
It is divided into two parts: the first covering fixed power supply systems, and the. Electrical substation is a utility where some special features like voltage level up & down, power factor correction, frequency up & down occurs. Say a certain generation station generates power in voltage level 11KV, then if it has supply power to the grid which is of KV then the generating station will need a substation Basic of Electrical Substation.

Loco pilot is required to switch off the locomotive circuit breaker while approaching the neutral section for which warning board is provided at and M before the. direct current, it is necessary to use an electronic power converter (rectifier). A traction rectifier is the essence of two components of the modern technology: electronics and industrial power engineering.

These railway substations and trackside protection enclosures are self-contained, fully integrated portable buildings which can be quickly positioned at the trackside and cabled up to a single marshalling kiosk.
Included in the enclosure are: A protection scheme especially designed for the unique railway power system application. The brief description of the system is given in Chapter 2 of Volume I. The 25 kV single phase conventional system as adopted on Indian Railways has been described in that chapter.

Voltage (EHV) at each traction substation which is owned, installed, operated and maintained by the Railways. The Railway receives 3-phase power supply from the supply Authority at a single point near the grid substation from where the Railway runs its own transmission lines providing its own traction sub-stations.
Abstract: The efficiency of a regenerative braking energy operation is discussed in this paper. Sending recovered energy back to the grid is possible using a reversible converter installed in a DC railway power substation.
The strategy of such converter impacts the efficiency of the recovered energy because of coupling between the converter strategy and the regenerative braking strategy of the.
If substations are equipped with inverters, recovered energy can be fed back into the supply grid whenever no other train is running close enough to use the recovered energy. Technical details The architecture and power electronics of DC substations are almost identical in most mass transit systems and mainly based on diode rectifiers.
Track Design Handbook for Light Rail Transit, Second Edition TRACTION POWER SUBSTATIONS Traction power substations take commercial alternating current power from the local utility company and convert it into the direct current required by the LRVs.
Pennsylvania Trolley Museum has a fairly complete Westinghouse KW rotary converter substation, but it's stored in pieces at the moment. The equipment came from a former Pittsburgh Railways substation, plus additions from a Duquesne Light Co. commercial VDC sub that served downtown Pittsburgh buildings until c The assembly of the apparatus used to change some characteristic (e.g.
voltage, a.c. to d.c., frequency, p.f etc.) of electric supply is called a sub-station. The four major types of substations are explained in this article. Sub-stations are an important part of the power system. The design of the entire substation was made keeping in mind the most basic requirements of a proper substation including the civil and domestic requirements.

The railway station has a special role in people's s: The last functioning rotary converter substation (using cycle power) was the Marble Hill Substation in The Bronx which was retired in May of Cos Cob When the New York, New Haven and Hartford Railroad was electrified during the first decade of the twentieth century, the conventional third rail type of power distribution was not used.
In the substations, the power would be reduced by transformer to (approximately) volts AC, and thence converted to (nominally) volts DC for the third rail (as well as the now-vanished trolleys and el's).
This last step was accomplished with rotary converters. A traction substation or traction current converter plant is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility. Our diverse power portfolio for rail and urban transport solutions is complemented by static frequency converter stations, power quality systems, network management systems, energy recuperation and energy storage systems as well as a broad range of system studies and dynamic traction power supply simulations based on powerful software tools.

The document is divided into 12 chapters starting from Electrical Arrangement to. Substations: As stated above, the substation is where the electricity from the supplying regional grid (at kV, kV, kV, or kV) is transformed to a voltage suitable for use for the railways, and fed to the various sections of the catenaries.
An AC substation is generally fed 3–phase power, and the phases are split out so that a. Hesop is an advanced reversible power substation which both supplies traction voltage to a network and recovers braking energy from vehicles.
It can be retrofitted to existing systems or built into new networks in construction phase. Our expertise in energy comes fully into play in Hesop’s key characteristics.

The energy infrastructure has been undergoing very rapid changes in recent years in order to increase the share of renewable energy sources such as wind and sun, which are by nature more distributed and variable.
Book Launch Party for Yellow Cab: A French Filmmaker’s American Dream Third rail power was produced by two different steam substations – one .Stations dedicated to the railway industry - traction substation including precast concrete produced in ZPUE S.A. The traction substation is a facility of the electric power traction, where electric power, which supplies electricity to the substation (HV or LV), is converted into electric power with parameters (type and voltage level) relevant to a particular electric traction power supply system.Today, this job is done in Substat and other MTA substations, by nondescript grey cabinets full of solid-state rectifiers.
But for decades, it was the job of converters like Rotary #1.
