Abstract

The invention discloses an early warning system and an early warning method of a marine nuclear power platform. The early warning system comprises a sensing network subsystem, a data storage subsystemand an early warning analysis subsystem, wherein the sensing network subsystem is used for acquiring and transmitting a real-time operation parameter of target equipment of the nuclear power platform. The data storage subsystem is used for storing the real-time operation parameter in a distributed manner. The early warning analysis subsystem is used for comparing the real-time operation parameterof the target equipment with a preset first-order threshold, determines whether the target equipment is in normal operation and displays an early warning result. The early warning system and the early warning method have advantages of realizing advanced precise positioning of a target equipment fault of the marine nuclear power platform, improving reliability of the nuclear power platform, overcoming blindness and excessive maintenance in periodical maintenance, reducing maintenance time and maintenance workload, and improving economic performance of the marine nuclear power platform. Furthermore the early warning system and the early warning method overcome defects of low pertinency and low efficiency in corrective maintenance and preventive maintenance of an existing nuclear power device.

Description

technical field [0001] The invention relates to the field of management of nuclear power platforms, in particular to an early warning system and an early warning method for marine nuclear power platforms. Background technique [0002] The marine nuclear power platform is an offshore floating nuclear power plant. The platform stack power is 100MWt×2 levels, the electric power is 25MWe×2 levels, and the service life is 40 years. After a period of operation, the platform needs to replace spent fuel and install new fuel. The refueling cycle is 1.5 years. Therefore, in order to ensure the long-term efficient and healthy operation of the platform, it is necessary to operate and maintain the platform throughout its life, and the maintenance guarantee method of the marine nuclear power platform provides a guarantee for the realization of the efficient utilization of the platform. [0003] At present, the maintenance support of nuclear power plants mainly includes maintenance and lo...
