【Abstract】 The design and realization of feed water, main steam temperature and burning control circuits using intelligent programmable controllers in the monitoring system of fossil-fired generating units has been introduced. Each controller can be regarded as a front-end connecting with the monitoring network. The controllers can be operated by high-level computer, or run separately out of the net. The structure of the monitoring system is simple. Operational results show that the monitoring system was reliable in operation and had good performance.更多还原
