1. Program overview

SIS (plant-level monitoring information system) is a plant-level automation information system that integrates real-time process monitoring, optimization control and production process management. It is located in the thermal power plant's distributed control system DCS and related auxiliary program control systems and plant-wide management information system MIS. A set of real-time plant-level monitoring information system in between. The main purpose of SIS system is unit performance calculation, plant-level economic analysis, plant-level load distribution and economic operation of the unit. The real-time nature of the SIS system is reflected in the real-time analysis of the operating parameters of the unit by the SIS system. Through the powerful data mining, data processing and optimization functions of the system, the operating conditions of the unit and the entire plant can be accurately analyzed, diagnosed and optimized; the SIS system Plant-level characteristics are reflected in the fact that the SIS system covers the DCS data information of the entire plant and the data information of the auxiliary control system, and realizes the optimization of the operation of the entire plant based on the analysis of the economics of the entire plant.
