Embodiment 1

[0037] Such as figure 1 , figure 2 As shown, the operation guidance system based on the typical thermal power plant and the accident case library is characterized in that: it includes the DCS data acquisition system of the thermal power plant unit, and it is characterized in that it also includes a memory, a processor and a display,

[0038] The storage guide function module is stored inside the memory, and the accident case library and typical operations are stored;

[0039] The processor encodes and classifies the fault information of different components of the thermal power plant, and through the analysis of the expert industry knowledge base and historical fault data, divides the normal threshold range of the thermal power unit operation index, mines the change rule of the index operation process, and constructs Data sample sets in different states, using machine learning algorithms to establish a fault trigger model;

[0040] The display at least includes the DCS smar...

Abstract

The invention belongs to the field of power plant safety control systems, and particularly relates to an operation guidance system based on a typical and accident case base of a thermal power plant. The operation guidance system comprises a data collection system (DCS) and is characteriazed in that a memory internally saves a mentoring function module, and stores an accident case base and typicaloperations; a processor encodes and classifies fault messages of different components of the thermal power plant; based on an expert industry knowledge base and analysis on historical fault data, normal threshold ranges of operating indicators of a thermal power unit are defined, a change rule in an operating process of the indicators is mined, data sample sets in different states are constructed,and a fault trigger model is established using a machine learning algorithm. When triggering conditions are reached, a display visually shows the location of a fault and a data distribution rule, andinformation about the cause of the fault and treatment suggestions is displayed on the display; fault early warning is accurate and the operation guidance is accurate and in place.

Description

technical field [0001] The invention belongs to the field of power plant safety control systems, in particular to an operation guidance system based on a thermal power plant typical and accident case library. Background technique [0002] The centralized control operation of thermal power plants is an important guarantee to ensure the safe and efficient operation of thermal power plants, that is, the operation level and accident handling level of centralized control operators directly affect the safe and economical operation of thermal power plants; especially in recent years, centralized control operators have become more and more Fewer (2 or 1) and tend to be younger, due to unskilled business level, resulting in a decline in operation and operation level, when unit operation abnormality or accident occurs, due to unskilled business technology or incomplete consideration, the abnormality or accident will expand, Seriously affect the normal production of thermal power plant...
