一种基于方位角测量的局部放电定位方法
摘要：
本发明公开了一种基于方位角测量的局部放电定位方法，包括步骤：(1)在检测现场设置由M×M个特高频传感器构成的特高频传感器平面阵列，该M×M个特高频传感器均匀分布；(2)构建平面坐标系，设局部放电源位于该平面坐标系中的坐标(x，y)处；(3)将特高频传感器平面阵列设置在平面坐标系内的第一位置(x1，y1)，则局部放电源与第一位置的夹角为局部放电第一方位角θ1；(4)获得第一方位角θ1；(5)将特高频传感器平面阵列移动至平面坐标系内的第二位置(x2，y2)，则局部放电源与第二位置的夹角为局部放电第二方位角θ2；(6)获得第二方位角θ2；(7)基于局部放电源的位置方程，获取局部放电源的坐标进行定位。
摘要（英）：

The invention discloses a partial discharge positioning method based on azimuth angle measurement. The method comprises the following steps of (1) setting an ultra-high frequency sensor planar array formed by M*M ultra-high frequency sensors at an inspection site, wherein the M*M ultra-high frequency sensors are uniformly distributed; (2) constructing a plane coordinate system, and setting a partial discharge source at a coordinate (x, y) in the plane coordinate system; (3) setting the ultra-high frequency sensor planar array at a first position (x1, y1) in the plane coordinate system, whereinthe included angle of the partial discharge source and the first position is a partial-discharge first azimuth angle theta 1; (4) acquiring the first azimuth angle theta 1; (5) moving the ultra-highfrequency sensor planar array to a second position (x2, y2) in the plane coordinate system, wherein the included angle of the partial discharge source and the second position is a partial-discharge second azimuth angle theta 2; (6) acquiring the second azimuth angle theta 2; and (7) based on the position equation of the partial discharge source, acquiring the coordinate of the partial discharge source and carrying out positioning.
