Abstract

The invention discloses a transformer device state maintaining guiding method based on TRIZ. The method comprises the following steps: establishing a transformer device state maintaining guiding model: setting a TRIZ inventive principle matrix, collecting the experience value sequences of parameters of various quantities of state in state maintaining of a transformer device to be guided in a TRIZ inventive principle domain, getting the discrete mapping sequence values reconstructed by the quantities of state, and getting complete correlation coefficients between the quantities of state and the TRIZ and constructing a transformer device guiding model; using the transformer device guiding model to guide the transformer device: collecting actual sequences of parameters of various quantities of state in state maintaining of the transformer device to be guided in the TRIZ inventive principle domain, getting the actual discrete mapping sequence values reconstructed by the quantities of state, getting the complete correlation coefficients between the quantities of state and the TRIZ inventive principle and getting the guided result of the transformer device. According to the invention, the accuracy of periodically evaluated results of the working states of a No.1 transformer device and a No.2 transformer device of a main transformer for a 220 KV station of a power grid is improved.

Description

Technical field [0001] The invention relates to the field of overhaul of power system substation equipment, in particular to a TRIZ-based state overhaul guidance method for substation equipment. Background technique [0002] Condition maintenance of substation equipment is a major change in the maintenance of power equipment, and is a production management method that is currently vigorously advocated by power grid operating companies. The feature of conditional maintenance is to perform on-demand maintenance based on the status of the equipment, avoid blindness, make the maintenance work more precise and scientific, and make the maintenance more effective. The power grid company has given guidelines for the state-of-the-art maintenance of substation equipment in the power grid. These guidelines are widely used in a large number of substation equipment in China. The current maintenance guidelines are evaluated manually based on traditional technology, and the manual-based state ...
