GSEG PVT LTD. hazira road, Surat.

v Introdution:-

The department of Mechanical Engineering, Bhagwan Mahawir College of engineering organized industrial visit to GSEG co. at hazira on April ,2016.

v Industry overview:-

Ø  GEB is a main contributor to power supply for the state

Ø  GSEG (Gujarat State Energy Generation Ltd.) is engaged in gas based generation of electricity, using innovative and dependable technology, in Gujarat. A Special Purpose Vehicle (SPV) of GSPC for generating power using advanced, eco-friendly technology, GSEG fits in well in the GSPC Group's overall scheme of energy business.

Ø  GSEG is committed to deliver true value in efficiency, economy and sustainable development activities in Gujarat. It presently operates a 156 MW Combined Cycle Power Plant near Hazira, Surat, which is being further expanded in the first phase by 350 MW.

Ø  GSEG achieved commercial operation of this Combined Cycle thermal power plant, within a record time of 22 months, starting June 1st, 2000. The first phase expansion by ~350 MW is already underway and is likely to be operational sometime in the second half of 2010.

Operations and Maintenance:-

It certainly requires competent operation management and maintenance to ensure the success of long-term investments in power plants and other facilities. This is why we offer you our services and experience:

• Advisory assistance

v Description of event:-

Ø  A batch of 60 students was taken to GSEG PVT LTD.

Ø  The power plant was fully automatic. Most of the work was done in main operator office there were many electrical and mechanical engineers in the field like operating and maintenance engineer. And there were also safety equipment’s for safety purpose.

Ø  The power plant was highly certified by ISO-9001.

Ø  GSEG Energy Services (India) Pvt. Ltd. (SESI) was set up in 2001 to provide cost-effective consultancy services of international standards by integrating resources of the Parent Company and those of SESI in India.

Ø  GSEG is a captive power plant. It sells and supplies the energy to GEB and then to the consumers.

First we take considerably knowledge about the steam power plant by Mr.____ and by Pro. Sagar Tailor.

v Steam power plant:-

Components of steam turbine:-

·         Boiler

·         Steam turbine

·         Condenser

·         Feed pump

·         Alternator

(steam turbine power plant)

Ø  A steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.

Ø After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam-electric power plants is due to the different fuel sources. It takes natural natural water as fuel.

Ø  The electric efficiency of a conventional steam-electric power plant is 33 to 48%. The rest of the energy must leave the plant in the form of heat. This waste heat can be disposed of with cooling water or in cooling towers.

v Gas turbine power plant:-

Components of gas turbine power plant:-                          

·         Air compressor

·         Combustion chamber

·         Turbine

(Gas turbine power plant)

Ø  First of all natural air is compressed into high pressure by a compressor.

Ø  Then fuel and compressed air are mixed in a combustion chamber and ignited.

Ø  Hot gases are given off, which spin the turbine wheels.

Ø  Gas turbines burn fuels such as oil, natural gas and pulverized(powdered) coal.

Ø  Gas turbines have three main parts: i) Air compressor ii) Combustion chamber iii) Turbine

Ø  The capacity of power generation of the power plant was 220 MW

v Safety in power plant:-

Ø  The plant follows the law and standard of ISO.

Ø  All the engineers and workers in the plant were wearing helmet and it was compulsory.

Ø  All the components and equipment’s were checked time to time by preventive maintenance 

Ø  There was fire alarm in every few distance

Ø  Power plant has a separate safety department.

v Grid system in power plant:-

Ø  An electrical grid is an interconnected network for delivering electricity from suppliers to consumers.

Ø  It consists of generating stations that produce electrical power, high-voltage transmission lines that carry power from distant sources to demand centers, and distribution lines that connect individual customers.

Ø  Power stations may be located near a fuel source, at a dam site, or to take advantage of renewable energy sources, and are often located away from heavily populated areas.

Ø  The electric power which is generated is stepped up to a higher voltage at which it connects to the electric power transmission network.

v HRS system in power plant:-

A waste heat recovery system (HRS) is an energy recovery heat exchanger that recovers heat from hot streams with potential high energy content, such as hot flue gases from steam from cooling towers or even waste water from different cooling processes such as in steel cooling.

Component of heat recovery system:-

·         Recuperators

·         Regenerators

·         Heat pipe exchanger

·         Thermal wheel and economizer.

·         Heat pumps

Recuperaters: This name is given to different types of heat exchanger that the exhaust gases are passed through, consisting of metal tubes that carry the inlet gas and thus preheating the gas before entering the process.

Regenerators: This is an industrial unit that reuses the same stream after processing. In this type of heat recovery, the heat is regenerated and reused in the process.

Heat pipe exchanger: Heat pipes are one of the best thermal conductors. They have the ability to transfer heat hundred times more than copper. The heat pipe is mainly used in space, process or air heating, in waste heat from a process is being transferred to the surrounding due to its transfer mechanism.

Thermal Wheel or rotary heat exchanger: consists of a circular honeycomb matrix of heat absorbing material, which is slowly rotated within the supply and exhaust air streams of an air handling system.

Economizer: In case of process boilers, waste heat in the exhaust gas is passed along a recuperator that carries the inlet fluid for the boiler and thus decreases thermal energy intake of the inlet fluid.

Heat pumps: Using an organic fluid that boils at a low temperature means that energy could be regenerated from waste fluids.

v Partners and affliation:

·         Long term gas supply arrangement (GSA) with GSPC, niko.

·         Long term power purchase arrangement (PPA) with GUVNL (GEB).

·         Alstom as erection procurement constructions (EPC) turnkey contracter  for CCPP.

·         Steag encotac for operations and maintenance of the CCPP Gujarat plant.

v Natural gas to power:-

·         GSEG is in the business of buildings new power generation plant to meet the energy challenges in Gujarat,

·         Its first and foremost demonstrable success is the natural gas powered combined cycle power plant at (surat), Gujarat, with an installed capacity of 156MW.

·         Supplied by Alstom and managed by steag encotec, both world leaders in advanced power technologies. The plant was designed, developed & led by highly qualified management and engineering personnel from all facets of the electric power industries under the auspices of GSEG.

v Achievements:-

In the present scenario, where almost All power projects are facing difficulties and hardly any new capacities are added to the system, GSEG has created a record of its own by synchronizing the first gas turbine in record time of 17 months & the second gas turbine in 18 months from zero date of EPC contract. Adding true value to energy needs of Gujarat, through efficiency, economy & environment friendly operations.

v GSEG’s strengths:-

·         One of the most efficient producers in Gujarat offering reliability and flexibility.

·         Applications of modern and efficient technologies – like CCPP and state of the art controls for plant management.

·         Committed to environment friendly operations.

·         Excellent domain expertise guaranteeing efficient and economic operations.

·         Regular modernization to continuously increase energy yields and environmental performance.
