THERMAL POWER PLANT- Sahil kumar shah.pptx

hey this is my ppt on thermal power plant

1. Vindhyachal Super Thermal Power Plant . By- Sahil kumar shah 4 th semester Electrical engineering NIT Raipur PROJECT REPORT

2. GIST Overview of VSTPP. Flow graph and layout. Basic Working. Chemicals used. Safety Precautions. Conclution .

3. Overview Vindhyachal Super Thermal Power is the largest thermal power plant in India. The total installed capacity is 4760mw Besides these it has 1 solar plant of capacity 15mw and 2 hydro power plants of capacity 4mw each. It consists of a total 13 units ,where 6 units are of capacity 210 mw and other 7 units are of capacity 500 mw. These 13 units are divided into 5 stages .

4. Overview Stage 1 consists of 6 units of 210 mw and stage 2,3,4 – each consists of 2 units of 500 mw and stage 5 consist 1 unit of 500 mw . It provide electricity to states madhya pradesh,chattisgarh , maharashtra , gujarat,goa , daman & diu and dadar nagar haveli .

8. Basic working of power plant As we know in a power plant electrical power is obtained from the fuel being used. A Thermal Power Plant makes use of Coal to boil water and produce steam. This steam is made to hit on the blades of the Steam turbine. From there further, the mechanical energy is converted to electricity using generators. We refer to them as thermal power plants because we make use of heat energy released by the burning of fuel to produce electricity.

10. Switchyard??? It is a switching station which has the following credits : ❖ Main link between Generating plant and Transmission system, which has a large influence on the security of the supply . ❖ Step-up and/or Step-down the voltage levels depending upon the Network Node . ❖ Switching ON/OFF Reactive Power Control devices, which has effect on Quality of power.

14. Switchgears Switchgear is one which makes or breaks the electrical supply. It operates in low voltage. This is the protection device which control the equipment or machine ( either heavy or small ) in the power system.

17. Reactors Reactors are also a transformer which is providing or consuming reactive power which is occurring by Ferranti Effect. Reactors connection are of two types :- Series Reactor Parallel Reactor

18. Reactors Series Reactor are used for consuming Overhauling Current in a transmission line. It is used for the safety of a plant . Parallel Reactor are used for consuming Reactive power KVAr . These Reactors are used in both side of a transmission line means at plant and substation . From where the electricity is control .

19. Safety and Precautions When thinking about safety in your power plant, a good place to start is reviewing the most common types of hazards in these facilities .  When you go through a safety audit, the team that runs it will assess your preparedness in each of the following four areas. They’ll let you know where you’re vulnerable and help you plug those holes before they turn into problems . 1. Electrical Shocks- Electrical shocks are one of the premier dangers that workers encounter while carrying out their duties at thermal power plants. These shocks can be especially dangerous because the electrical equipment in these facilities is designed to process extremely large amounts of electricity.

20. Safety and Precautions 2. Contact with Hazardous Chemicals- Power plant workers are also routinely exposed to materials and chemicals that can be dangerous to come into contact with, which include: Corrosives (acids and bases) Oxidizers Solvents 3. Falls- Many thermal power plants have large pieces of equipment spread across multiple stories. When employees work on these

21. Safety and Precautions 4. Fire Safety in Thermal Power Plants- Fire safety in thermal power plants is another important focus for you. Various pieces of equipment use flames and sparks to do their jobs. And that opens up the risk of a fire occurring in your plant, which is why safety audits in thermal power plants tend to focus on fire safety.

22. Safety and Precautions When viewing flames or furnace conditions, always wear tinted goggles or a tinted shield to protect the eyes from harmful light intensity and flying ash or slag particles . Do not use open-ended pipes for rodding observation ports or slag on furnace walls. Hot gases can be discharged through the open-ended pipe directly onto its handler. The pipe can also become excessively hot . When handling any type of rod or probe in the furnace, especially in coal-fired furnaces, be prepared for falling slag striking the rod or probe. The fulcrum action can inflict severe injuries . Be prepared for hot water in drums and headers when removing manhole plates and handhole covers . Do not enter a confined space until it has been cooled, purged of combustible and dangerous gases and properly ventilated with precautions taken to keep the entrance open. Station a worker at the entrance and notify the responsible person

24. Conclution The training at NTPC Vindhyachal was altogether an exotic experience, since work, culture and mutual cooperation was excellent here. Moreover fruitful result of adherence to quality control awareness of safety and employees were fare which is much evident here.
