Analysis on fault of flow data acquisition of intelligent terminal in heat supply network of 300MW power plant and solution

Abstract

Abstract:

Abstract:The control section of the heat supply network of the 300MW thermal power plant consists of a programmable logic controller and an intelligent terminal data collecting system. The intelligent terminal collecting system collects the data of the flow, the pressure and the temperature for metering and charging settlement. The communication of the intelligent terminal system and the intelligent transmitters is not compatible, which caused the flow data collected by the intelligent terminal to be incorrect. The reason of the fault was analyzed, and relevant solution was given.

Key words: Key words:thermal power plant, intelligent terminal, programmable logic controller (PLC), transmitter, flow data acquisition
