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
