COMPUTER CONTROL OF POWER SYSTEMS

INTRODUCTION

·         Increase in unit size, growth of interconnected and the need to maintain the system in normal mode require sophisticated control, instrumentation and protection.

·         The multiplicity of monitering instruments in the control room and their distance apart make the observation of more than a few vitaloncs almost impossible, especially during the intense activity of plant start up.

·         The operation of changing plot parameters and take critical decisions.

·         These requirements led to the development and application of more advanced solid state modular electronic instruments, computer based direct control and date processing systems.
