Thermal power generating unit intelligent control system based on big data

Abstract

The invention discloses a thermal power generating unit intelligent control system based on big data. The system comprises an OPC interface server, a big data server, a programmable controller, an MODBUS communication card, an EtherNet / IP Ethernet communication card, a debugging machine, and a PROFIBUS-DP / MODBUS communication gateway,wherein the big data server is connected with the decentralizedcontrol system database through the OPC interface server; the big data server is connected with the programmable controller through the MODBUS communication card; the debugging machine is connected with the programmable controller through the EtherNet / IP Ethernet communication card. The programmable controller is connected to the decentralized control system through the controller MODBUS communication card and the PROFIBUS-DP / MODBUS communication gateway, the control mode depends on the big data mining technology to complete the intelligent control process, the safety is good, the accuracy ishigh, and the intelligent control potential of the generating unit is effectively improved.

Description

technical field [0001] The invention belongs to the field of big data control of thermal power units, and relates to an intelligent control system of thermal power units based on big data. Background technique [0002] In recent years, the development goals of thermal power units have gradually been to improve efficiency, save energy, improve the environment and reduce costs. Especially for units with deep peak-shaving capabilities, the strict assessment indicators contradict each other with the complex operating conditions of the units, resulting in dependence on The economic situation of thermal power units with traditional control methods is becoming increasingly severe. The State Council's "Internet +" smart energy key action pointed out that my country should rely on the existing Internet and cloud computing platforms to gradually realize the interconnection and sharing of dynamic monitoring information at all levels, and further improve the energy consumption online mo...
