High-security-level optimal control device

Abstract

The invention relates to a high-security-level optimal control device, which comprises a power module, a security-level communication module, a control center module and a signal line module, whereinthe power module is electrically connected with the security-level communication module, the control center module and the signal line module and used for providing electric energy needed by work of the security-level communication module, the control center module and the signal line module; and the security-level communication module is connected with the control center module through the signalline module. According to the high-security-level optimal control device, the security-level FPGA technology and the security-level CPLD technology are utilized, software does not adopt any soft coreor other components, all hardware circuits are designed into combinational logic and sequential logic, hot plug is supported, and the security coefficient is improved; and EMC and other protection circuits are adopted, electromagnetic radiation and other related interferences are eliminated, and a power plant protection system is enabled to achieve normalized and standardized operation.

Description

technical field [0001] The invention belongs to the technical field of security control, and in particular relates to a high security level optimal control device. Background technique [0002] With the rapid development of social economy, electric power has become an indispensable part of social development and people's life. While power plants are generating electricity, safety accidents often occur due to a series of reasons such as equipment failures, management lags, and operational violations, resulting in A series of adverse effects such as loss of production equipment, damage to the ecological environment, and casualties. [0003] Although there are many reasons for investigating the safety accidents in power plants, they all boil down to the failure to detect and deal with failures in time due to failures or illegal operations, or failure to deal with and eliminate failures in time afterwards. In the current work of power plants, In emergencies, most of them rely o...

[0003] Although there are many reasons for investigating the safety accidents in power plants, they all boil down to the failure to detect and deal with failures in time due to failures or illegal operations, or failure to deal with and eliminate failures in time afterwards. In the current work of power plants, In emergencies, most of them rely on the PLC system or human operation to shut down the boiler or reactor. There are still problems such as untimely response, low safety factor, and difficulty in adapting to special working environments such as electromagnetic interference. In order to eliminate and avoid power plants as much as possible The occurrence of safety accidents can avoid the loss of human, material and financial resources and the impact on the ecological environment, improve the automation level of the safety protection system of the power plant, meet the special working environment such as high temperature, high pressure, and radiation of the power plant, and ensure the optimal control safety level
