Optimization method of key state parameters of power distribution switch device

Abstract

The invention relates to the field of state evaluation of electrical equipment, particularly to an optimization method of key state parameters of a power distribution switch device. The method comprises establishing an original variable library for obtainable power distribution device state parameters according to existing technological means and existing historical data and test data; utilizing a principal component analysis method to optimize original variables to convert multiple relevant variables into multiple irrelevant variables which contain a large part of information of the original variables; taking the obtained new variables as the input variables of state evaluation of the power distribution switch device. The method can help extract main content of multi-dimensional data to obtain the most useful information, to eliminate useless information and further achieve data optimization, thereby clarifying sample classification and further improving accuracy and reliability of state evaluation of the power distribution switch device.

Problems solved by technology

However, due to the variety of state quantities of distribution switchgear and the large input original sample data, the structure of the state evaluation model is also very complicated.

Moreover, a large amount of original data may also greatly reduce the reliability of the evaluation results due to excessive data fluctuations and interference from wrong samples.
