Comparison and Application of Programmable Logic Controller and Distributed Control System in Coal Handling System

Huixin Zhang

Abstract

PLC was used much more than DCS in coal handling system in existing power plants. In this paper, DCS and PLC were compared over technology and economy to better serve the construction bidding and project implementation. Seen from the comparison results and the requirements of unified hardware platform, taking DCS in coal handling system is the trend.
