Series & shunt compensation and FACTs Deviceskhemraj298
Series compensation is used to improve the performance of extra high voltage transmission lines by connecting capacitors in series with the line. It allows for increased transmission capacity and improved system stability by reducing the phase angle between sending and receiving end voltages for the same power transfer. Shunt compensation controls the receiving end voltage by connecting shunt capacitors or reactors to meet reactive power demand and prevent voltage drops or rises. Flexible AC transmission systems use high-speed thyristors to switch transmission line components like capacitors and reactors to control parameters like voltages and reactances to optimize power transfer.
Final year project ideas for electrical engineering eepowerschool.comMuhammad Sarwar
Final year project is the ultimate achievement of an electrical engineering graduate. The idea
of a final year project is to practically implement the technical and professional skills learned.
Graduates work on different final year project ideas. The title of an FYP should be novel and
the project must have a positive impact on the society. Many students choose their FYP topic
in a haste, and at the end of completion, it’s no good for them. So, choose your final year
project wisely and give a lot of thinking while choosing final year project ideas for your
electrical engineering degree.
This post gives a complete list of final year project ideas for electrical engineering students. A
short summary (or synopsis) of the project has also been given to get the complete
understanding of the project. The summary contains a short introduction, methodology and
project outcomes.
Undergraduate students of BSEE are encouraged to pick a topic that would implement a novel
research idea. Though, only simulations can also be used instead of a design project. Various
simulation softwares are available to implement the FYP e.g, Matlab/Simulink, Power World
Simulator, ETAP, Digsilent PowerFactory, PSCAD etc.

Economics of Power Generation
A power station is required to deliver
power to a large number of consumers
to meet their requirements. While de-
signing and building a power station, efforts
should be made to achieve overall economy so
that the per unit cost of production is as low as
possible. This will enable the electric supply
company to sell electrical energy at a profit and
ensure reliable service. The problem of deter-
mining the cost of production of electrical en-
ergy is highly complex and poses a challenge to
power engineers. There are several factors which
influence the production cost such as cost of land
and equipment, depreciation of equipment, inter-
est on capital investment etc. Therefore, a care-
ful study has to be made to calculate the cost of
production. In this chapter, we shall focus our
attention on the various aspects of economics of
power generation.
Abstract:-This paper deals with open loop study of fixed capacitor thyristor controlled reactor (FC-TCR) system simulation using Matlab/Simulink for various loading. The modelling of the FC-TCR is verified using the Matlab/Simulink. First power flow results are obtained and power profile have been studied for an uncompensated then results are compared with the results obtained after compensating using the FC-TCR.Its observed that current drawn by FC-TCR is varied by changing firing angle. In compensation without FC-TCR, load increases and power factor become less and in compensation with FC-TCR, load increases and power factor become near to the unity.Hence by providing compensation Voltage, power profile of system will be improved and system losses are reduced.

The system provides an economical way to automatically correct power factor using static capacitors.

This document discusses the selection of circuit breakers. It begins by defining a circuit breaker as a protective device that is used to automatically open the faulty part of a power system during a fault. There are two main factors considered when selecting a circuit breaker: 1) its normal working power level and fault level ratings, which are specified by the rated interrupting current or MVA, and 2) its momentary current and speed ratings. The momentary current rating must be higher than the maximum current during fault conditions, while the speed rating depends on transient fault currents and specified cycles. Multiplying factors are used to determine the circuit breaker's short circuit interrupting current from fault analysis calculations.

Analysis and Implementation of Solid-State Relays in Industrial application F...IJMREMJournal
There are many applications and circumstances where switching devices are required for proper operation,
controlling and isolating the high power and low power systems. The most widely used switching devices are
electromechanical relays and solid state relays. In this work, analysis and implementation of solid state relays over
electromechanical relays with respect to instantaneous current supply inindustrial application is conducted and
compared. For this purpose, an experimental setup is arranged for switching operation of electromechanical relays
and solid-state relays.The results of voltage and the current transients are analyzed and compared. It was observed
that there are no transients occurred during switching of solid state relays where as during switching of
electromechanical relay transients observed in volatge and current waveforms. So, it is advisable to use the solid
state relays over electromagnetic relay for safe and smooth operation of the system.

INSTRUCTIONS TO THE CANDIDATE
SAFETY:
You are doing experiments in Power Electronics lab with high voltage and
high current electric power. It may cause even a fatal or loss of energy of your
body system. To avoid this please keep in mind the followings
In case of any wrong observations, you have to SWITCH OFF the power
supply related with it.
You have to tuck in your shirts or wear an overcoat.
You have to wear shoes compulsorily and stand on mats made by
insulating materials to electrically isolate your body from the earth.
ATTENDANCE:
If you absent for a lab class then you have lost several things to learn.
Laboratory should be treated as temple, which will decide your life. So don’t fail
to make your presence with your record notebook having completed
experiments, observation with completed experiments, day’s experiment
particulars with required knowledge about it and stationeries.
RECORD:
Shows the performance of equipment and yourself. It will be very useful
for future reference. So keep it as follows.
Write neatly; as they have to be preserved enter the readings in the record
notebook those have been written in your observation.
Units should be written for all quantities.
Draw necessary graphs and complete the record before coming to the
next lab class.
Don’t forget to write the theory with precaution and inference of each
experiment.
MAY I HELP YOU
1. Device ratings should be noted.
