Large Density Circulating Fluidized Bed Waste Incineration Power Plant Monitoring System Development And Research

This paper is subject to national emphasized groundwork research item about the disposal of the city waste using incineration , and it focuses on the research of the monitoring and controlling system of the multilayer Circulation Fluidized Bed boiler which is used in Hangzhou Qiaosi Power Plant, while considering an utilizing advanced technology and experience domestically and abroad. The key points of this paper include the design of software and hardware of the system, and the realization of automatic control function.The monitoring and controlling system adopts a total distributed control system (DCS) constituted by a programmable logic controller (PLC), a computer (PC) and thermal power engineering signal sensors,sender, controller, etc . PLC is used to collect data and perform automatic control mostly, while PC is adopted to monitor the operation process,analyze,display and store data. We also upbuild intranet between the different DCS systems to transfer the real time data and communicate.This paper contents software development of PLC and PC. The software for PC developed by Visual C++. The software for PLC programmed by STEP 7, The communication module programmed by Winsock Application Programming Interface.The design of an automatic control system for the Hangzhou Qiaosi Power Plant is also included in this paper. The system uses intelligent PID controller and fuzzy controller to design automatic control loops, and performs the adjustment of PID parameters.
