Embodiment Construction

[0019] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 Shown is the structure diagram of the integrated controller of the power plant. The integrated controller of the power plant fully considers the control characteristics of the main control system, auxiliary control system and electrical system of the power plant in terms of application structure, and adopts fieldbus control technology, including internal high-speed DP bus, main control system and auxiliary control system of the power plant. The signal of the system thermal equipment is directly connected to the standard IO board of the controller through hard wiring, and the integrated controller completes data acquisition through the internal bus DP. At the same time, it can be connected with the fieldbus interface card through the high-speed PCIE bus. The fieldbus interface card supports various standard fi...

Abstract

The invention discloses a power plant integrated controller integrating communication management and programmable logic control. The power plant integrated controller is an integrated base control platform of a power plant data communication system (DCS), a national communication system and an auxiliary system. The power plant integrated controller includes all the functions of a traditional power plant system DSC controller. The power plant integrated controller is capable of making a control strategy according to technological requirements and control methods of a main engine, an auxiliary engine and electrical equipment, achieving a process control task through the programmable logic control, ensuring coordinate and orderly work of a control device of a power plant, completing communication access, control, management, system diagnosis and the like of intelligent equipment and electrical equipment and other intelligent electronic devices (IED) due to a professional IED device management module, using a field bus technology to achieve collection of field process signals and communication access of the intelligent equipment, managing network variable using a special mode of project design document (PPD), achieving share of data information among controllers, and at the same time improving reliability of the integrated design through various reliable design methods such as hardware, network redundancy and the like.

Description

technical field [0001] The invention belongs to the technical field of power plant control, and in particular relates to an integrated controller for the power plant, which can complete the integrated design of the main control system, the auxiliary control system and the electrical system of the power plant. While completing system control tasks, it can also carry out safe information sharing. Background technique [0002] Power plants are generally divided into three main control systems according to the control process: electrical system, main control system, and auxiliary control system. At present, the main control system adopts the DCS system platform to complete the control task, and the auxiliary system mostly adopts PLC control. The electrical equipment is essentially different from the thermal equipment in terms of equipment characteristics, control tasks, and system structure. In power plants, special electrical equipment is generally equipped. System (NCS system...
