Embodiment Construction

[0023] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and through specific embodiments.

[0024] figure 1 It is a schematic diagram of the structure of the thermal-technical-electrical integration control system in a power plant. It mainly includes monitoring master station, unit unit and public system. The unit unit is composed of a thermal automation system and a plant electrical automation system, and the public system is composed of a booster station automation system. The server of the monitoring master station is connected to both the distributed processing unit (ie controller DPU) and the public system through the monitoring layer network (Ethernet) to form the real-time information backbone network of the system, which is responsible for the data information between the distributed processing units. Collection and management; an isolation device is set between the unit unit and t...

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...
