Abstract

The invention discloses a spatial position determining method for a sensor array with four array elements. The method comprises that simulation parameters of a transformer are received; multiple groups of coordinate parameters of the sensors in the sensor array are obtained, the sensor array is used to locate a discharge source of the transformer, and each group of coordinate parameters corresponds to one spatial position of the sensor array; the positioning coverage rate of the discharge source is calculated in the simulation manner according to the simulation parameters and the multiple groups of coordinate parameters to obtain multiple simulation results; a simulation result in which the positioning coverage rate of the discharge resource is maximal is selected from the simulation results; and the spatial position corresponding to the simulation result in which the positioning coverage rate of the discharge resource serves as the spatial position of the sensor array. Thus, the problem that in the prior art the sensor array with the four array elements is low in the coverage rate for positioning the discharge source is solved.

Description

Technical field [0001] The invention relates to the field of simulation, and in particular to a method and device for determining the spatial position of a four-array sensor array. Background technique [0002] At present, in the location measurement of the transformer partial discharge source, the UHF positioning technology is usually used for positioning. Among them, the UHF positioning technology uses a four-element sensor array to detect the partial discharge electromagnetic wave signal, and reads the start of each signal. Start time and do the difference, you can get three relative propagation time values ​​(that is, the propagation time difference), based on which the propagation time-distance difference equation set, also called the time difference equation set. By using the Newton iterative positioning algorithm to solve the equations, the position coordinates of the discharge source can be obtained. [0003] However, through theoretical analysis, there are many factors th...
