Thermal power generating unit short period reliability assessment method and device based on fault early warning technology

Abstract

The invention provides a thermal power generating unit short period reliability assessment method and device based on the fault early warning technology, thus evaluating the thermal power generating unit reliability on the basis of equipment early stage fault early warning, and providing the maximum processing curve in a future period.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a short-term reliability evaluation method and device for thermal power units based on fault warning technology. Background technique [0002] Thermal power generation is a relatively special production system. On the one hand, the unit must be kept running for a long time, and on the other hand, the operating status must be constantly changed according to the grid dispatching requirements. This mode of operation makes the occurrence of various faults inevitable, which in turn affects the safety and economy of the production process. [0003] However, the current research is biased towards the fault diagnosis of the unit, and the early fault warning of the equipment cannot be realized. The reliability analysis of thermal power units tends to be traditional. The research is on the inherent reliability of the equipment, which reflects the performance change trend ...
