Thermotechnical electrical integrated control system for thermal power plant

Abstract

The invention discloses a system for realizing thermotechnical electrical integrated control of a power plant. The system comprises a unit set, a booster station and a thermotechnical electrical integrated monitoring master station, wherein the monitoring master station is connected with a decentralized processing unit (controller DPU) through a monitoring layer network, thereby forming a system real-time information backbone network for collecting and managing data information between the monitoring master station and the decentralized processing unit; and meanwhile, an electric communication card is used for finishing the data collection and management of various electric intelligent devices; in the electric devices, the devices closely related to a production technology are incorporated into the decentralized processing unit, the device control is finished and the process automation is emphasized; and in the electric devices, a plant power supply, an incorporated unit related to the booster station and public electric devices are monitored and the monitoring is emphasized. In the system provided by the invention, the control functions of the electric devices and the thermotechnical device of the power plant are seamlessly fused, and the system is fully oriented to a process flow of electrical production.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to providing a unified software and hardware platform for the whole plant control of a power plant. Background technique [0002] With the implementation of the national energy policy, energy saving, consumption reduction and reliability improvement are the essential requirements for thermal power plants to improve operating efficiency. Power Plant Grid-connected Operation Management Implementation Rules, began to vigorously assess and compensate the reliability and scheduling performance of grid-connected generating units. These measures make it necessary for thermal power plants to continuously strengthen the efficiency, operational safety and reliability of generating units. In order to adapt to the market development trend and improve competitiveness, the power generation group is gradually improving the layered management model. The power plant layer is gradua...
