This can be done by speed will vary with consequent change in frequency regulating the active and reactive power generated in the which may be highly undesirable maximum system. This is done to avoid the mismatch between the permissible change in power frequency is ±0.5hz. In generation and the load variations. Automatic Generation modern large interconnected system, manual Control (AGC) is one of the most important issues in electric regulation is not feasible and therefore automatic power system design and operation. The objective of the AGC generation and voltage regulation equipment is in a power system is to maintain the frequency of the area. If installed on each generator. If load is increase at time interconnected power system is considered then the tie-line frequency get decreased to maintain constant power is to be kept close to the scheduled values by adjusting frequency by using AGC. Through automatic the MW outputs the AGC generators so as to accommodate generation control we are maintain system fluctuating load demands. frequency constant.

CONTROL
1. INTRODUCTION Automatic generation control is requiring for controlling the electric power generation. Power system consists generation, transmission and distribution. In power system automatic generation control (AGC) is a system to control the output of generation. Due to sudden change in load frequency decrease or increase this will effect on the speed of the turbine. If constant frequency is not maintained it will affect the whole power system. Hence equipment of power system gets damaged. In an electrical power system AGC i.e. Automatic generation control is a technique of adjusting the power output of multiple generation units with respect to changes in the load. The performance of the system is judged according to the frequency. It’s measured whether it is increasing or decreasing. Power system operation considered so far was under condition of steady load. However both active and reactive power demands are never steady and the continually change with the rising or falling trend. Steam input to turbo generator must, © 2017, IRJET
