STEAM POWER PLANT

Steam Power Plant:

A Steam Power Plant is also known as a Thermal Power Plant.This provides the major share of Electrical Energy in India as well as in other Countries.In Steam Power Plants,the heat of combustion of fossil fuels such as Coal,Oil and Gas is utilised by the Boilers to raise Steam at High Pressure and Temperature.

Steam Power Plant

The Steam so produced is used in driving the Steam Turbine or sometimes steam Engine coupled to Generators and thus in Generating Electrical Energy.

Essential features of such power plants are Boilers, Turbines coupled to electrical generators,condensers and large number of auxiliaries.

The Thermal Efficiency of Steam Power Plant is quite low that is about 30% and Overall Efficiency is about 29% .In steam power plants more than 50% of total heat of combustion is lost as heat rejected to the condenser.

SWITCHING TRANSIENTS IN TRANSFORMER

Switching Transients: The word Transients is always very Scary for me but not any more hahaaa...........what about you???? Well coming to the point...why do these Switching Transients occur in a Transformer. When the switch is closed when the voltage is maximum...then the flux required by the core is zero and the available flux in the core is also zero and hence NORMAL OPERATION is sufficient When the switch is closed when the voltage is crossing zero...then the flux required by the core is maximum but here the avaliable flux in the core is zero and hence TRANSIENT OPERATION is required Here when the Transient operation takes place then the flux doubles gradually and this is known as Doubling Effect of Transformer.This Doubling Effect causes magnetic in rush current and Damage in the insulation. Using Secondary Harmonic Restraining Coil can reduce all these Drawbacks.

TRANSMISSION LINES

Transmission lines The Transmission lines are basically Electrical Circuits having distributed constants such as Resistance,Inductance and Capacitance.These contants are uniformly distributed along the length of the line and there concentration at any particular point is not possible Basically these Transmission lines are Classified based on two cases, CASE 1: BASED ON LENGTH:- The Tranmission lines are classified into three types here 1.Short Transmission Lines:When the length of the Tranmission line is below 60 km then they are considered to be under STL 2.Medium Transmission Lines:When the length of the Transmission line is 80-160 km then they are said to be MTL. 3.Long Transmission Lines: When the length of the Transmission line is above 160 km then they are said to be LTL. CASE 2: BASED ON OPERATING VOLTAGE:- Here the Transmission lines are classified into five types 1.Low Voltage:When the operating voltage is upto 1KV. 2.High Voltage:When the operat...
