局部放电全站定位综合算法

提出了一种适用于变电站大范围监测的局部放电定位算法。该算法基于接收信号指示强度（RSSI）,结合传感器数据实际情况补充计算节点。与传统三边加权定位方式不同,引入不定量条定位中垂线与三边区域共同加权。该模型考虑现实情况下放电位置在高度轴上与传感器群不在一个平面的情况,通过中垂线的引入可以有效地抑制定位误差。实验结果表明,所提出的改进定位模型能有效地匹配现实放电监测硬件,定位误差小于传统三边加权定位,结果符合工程要求。

Improved Algorithm on Wide Range Positioning for Partial Discharge in Substation

This paper proposes an improved positioning algorithm of electrical partial discharge applied for substations. The algorithm is based on the received signal strength of indication(RSSI) and replenishes beacon nodes by considering practical condition of the sensors. Compared with traditional trilateral weighting positioning algorithm, the proposed algorithm can improve the positioning accuracy by calculating the weighting results of the indefinite quantitative positioning perpendicular bisector and trilateral districts. This model considers the reality that the height of electrical discharge spots differentiates from the height of the plane formed by beacon nodes (signal sensors). The experimental result indicates that the revised positioning model proposed in this paper can effectively fit the condition of monitoring hardware and has higher positioning accuracy than the traditional trilateral positioning.
