INTRODUCTION
The rising importance of middle-range power operations andenvironmental preservation requirements at thermal power stationshas brought the need for more sophisticated operation and control.
Meanwhile, in response to the changing circumstances of theelectric power industry, systems must be implemented, that can alsomeet requirements such as cost effectiveness and labor savings.
The technical advances such as implementation of protectivefunctions by printed circuit boards, software configure system andcommon sensor system

This project has introduced the new technologies applied in labor-saving systems that as a thermal power plant supervisory andcontrol systems aim to be economical while maintaining a highdegree of reliability.
The systems discussed are the first to meet the need for a remotecentralized supervisory and control system and result from asuccessful fusion of latest digital control equipment, computertechnology and the excellent operational skills built up by theelectric power company.
CONCLUSION
