2. INTRODUCTION
The rising importance of middle-range power operations and
environmental preservation requirements at thermal power stations
has brought the need for more sophisticated operation and control.
Meanwhile, in response to the changing circumstances of the
electric power industry, systems must be implemented, that can also
meet requirements such as cost effectiveness and labor savings.
The technical advances such as implementation of protective
functions by printed circuit boards, software configure system and
common sensor system

23. Control Boards

24. This project has introduced the new technologies applied in labor-
saving systems that as a thermal power plant supervisory and
control systems aim to be economical while maintaining a high
degree of reliability.
The systems discussed are the first to meet the need for a remote
centralized supervisory and control system and result from a
successful fusion of latest digital control equipment, computer
technology and the excellent operational skills built up by the
electric power company.
CONCLUSION
