| Abstract: |
| A SCADA system for the water and steam quality control of the thermal system in power plants is introduced,which adopts the PID (Proportion Integration Differential) control algorithm with human intelligence simulation.The algorithm applied can avoid the defect of chemical feeding system vibration caused by the delayed feedback.The SCADA system uses the communication technology of DDE and Winsock between Client/Server application programs,realizing the reform of FIX log module and net information sharing. |
