Abstract

The invention relates to a method and system for determining an overall state of a converter valve. The method includes the steps of establishing a model for determining an overall state of a converter valve, defining levels of the overall state of the converter valve, and determining a factor layer and an indicator layer of the model; determining weights of various specific indicators in the indicator layer by an analytic hierarchy process; synthesizing states of the various specific indicators corresponding to various factors in the factor layer by a fuzzy comprehensive evaluation method to determine states of the various factors in the factor layer; and integrating the states of the various factors by evidence reasoning to determine the overall state of the converter valve. The system includes a state determination model establishing unit, an indicator weight determining unit, a factor state determining unit and a state level determining unit.

Description

technical field [0001] The present invention relates to the field of converter valve state determination, and more particularly, to a method and system for determining the overall state of a converter valve. Background technique [0002] Determining the state of the converter valve is the basis for the condition maintenance of the converter valve. Accurately and effectively determining the health state of converter valves in operation is one of the hot issues in research at home and abroad. The key to state determination is to establish a reasonable state determination model based on non-destructive indicators obtained from preventive tests, so as to judge The operating state of the diverter valve. Although the research on state determination technology has been actively carried out at home and abroad, the current state determination methods are mostly focused on qualitative, without a more detailed division of relative advantages and disadvantages, and a reliable and accur...
