Apparent‚ and Reactive Power According to Chipkin (2009)‚ we could think of Real Power as useful power – a measure of how much work is being done. Apparent Power is the power delivered by a power source to a load like a motor. They also stated that you need to supply more power (Apparent Power) to a device than it will do the work (Real Power). Reactive Power is the (vector) difference between Apparent Power and Real Power. Reactive Power cannot be harnessed to do useful work. Power Quality Disturbances

sector. Power line communication has many new service possibilities on the data transferring via power lines without use extra cables. AMR is a very important application in these possibilities due to every user connected each other via modems using power lines. AMR is a technique to facilitate remote readings energy consumption. Improving the electrical power supply to households as a big issue. The government has set a specific goal to raise the distribution rate of electrical power supply

INTRODUCTION: Indian Power sector has been evolved over a period of time. Power sector started opening up to private participation from 1992 when the largest FDI has been approved in the form of ENPRON POWER PROJECT in the state of Maharashtra. The tariff structure has been changed from single part tariff to two part tariff. The tariff includes the fixed cost and the variable cost. Most of the countries coal reserve lies in the eastern part of the country while most of the power consumption states

1. Introduction to Power Engineering 1.1 Power System Functions The traditional power system is arranged as a hierarchy. Generators feed into a high voltage transmission system that facilitates bulk transfers of power over large distances. Connected to the transmission system are medium voltage distribution networks that take power from grid supply points and deliver it to the customers who are supplied a low voltage. For a lot of its history‚ the electricity supply industry has operated as

12 Power System Stability 12.1 INTRODUCTION The stability of an interconnected power system is its ability to return to normal or stable operation after having been subjected to some form of disturbance. Conversely‚ instability means a condition denoting loss of synchronism or falling out of step. Stability considerations have been recognized as an essential part of power system planning for a long time. With interconnected systems continually growing in size and extending over vast geographical
