摘要
针对北斗定位技术在变电站智能运检管理系统中的应用需求,研究了基于北斗导航定位系统的定位算法。文中对于“北斗一代”定位系统采用了双星三球交汇方法,通过建立3个坐标方程实现了对用户位置的求解。对于采用了RNSS技术的“北斗二代”系统,通过采集四颗同步卫星的测距信息,建立非线性话的坐标方程利用泰勒级数将其转变为线性方程,然后利用最小二乘法来求解用户坐标。通过仿真算例,对该算法的有效性进行了验证,计算实现了对用户坐标信息的准确求解和定位。研究内容为实现北斗导航系统,在电力变电站智能运检管理系统中的应用提供了参考。
Aiming at the application requirement of Beidou positioning technology in substation intelligent operation and inspection management system,this paper studies the positioning algorithm based on Beidou navigation and positioning system.For Beidou Generation positioning system,this paper adopts the method of intersection of two stars and three spheres,and solves the user's position by establishing three coordinate equations.For the"Beidou II"system using RNSS technology,this paper collects ranging information of four synchronous satellites,establishes coordinate equation of non-linear speech,transforms it into linear equation by Taylor series,and then uses least square method to solve user coordinates.Finally,a simulation example is given to verify the validity of the proposed algorithm.The calculation achieves the accurate solution and location of user coordinate information.The research content of this paper is of great significance for the application of Beidou navigation system in intelligent operation and inspection management system of power substation.
