Abstract

The invention relates to a method for setting accidence diagnose and accidence prediction, which comprises a real-time data interface and a processing module. It provides many kinds of data interfaces to collect and treat data. Wherein, the accidence diagnose and accident prediction module can real-time detect the state of device, and diagnose accidence to alarm and give treating advice; the process detecting, accidence diagnose, accidence analysis and prediction are based on real-time data, that used in process control system; it uses the real-time and history database system modules to provide to the data service of alarm processing module, and provide the quick search of real-time and history data via function type; the alarm unit comprises an alarm operation function treating unit, an alarm container and an alarm manage unit. The invention can integrate the process detection, accidence diagnose, accidence analysis prediction and on-line operation instruction.

Description

1. Technical field

[0001] The invention relates to a system for safe production operation and management of a power plant enterprise, specifically a set method and system for fault diagnosis and accident forecast. 2. Background technology

[0002] my country's thermal power units are restricted by subjective and objective factors such as manufacturing processes and materials, design and installation levels, and operating technical conditions, especially fuel variability and peak-shaving operation methods. There is quite a gap. Statistics show that the failure rate of boiler body, water supply system, steam turbine body, generator body and other equipment is relatively high. According to the statistics of China Electric Power Federation in 2003, the average number of unplanned outages of 135MW units in five years reached 4.1 times per year. According to the statistics of the China Electric Power Federation in 2003, the 300MW unit had a clear downward trend in the past five y...
