为了能够较为准确地定位出电站锅炉“四管”泄漏的位置，对电站锅炉安全运行起到至关重要的作用，因此，将应用于蜂窝网络中的Chan算法和Taylor级数展开法的协同定位算法拓展到三维空间定位，并且通过计算机仿真电站锅炉的声学测点来分析比较该算法的性能：在不同的声波到达时间差（TDOA）估计误差、不同泄漏点位置以及不同声学测点布置个数的条件下分析对算法性能的影响，并且与Chan算法进行比较分析。仿真结果表明，Chan-Taylor协同算法在三维空间的定位性能要优于Chan算法，并且发现不同的声学测点布置情况对定位算法的误差存在一定的影响，因此，验证了Chan-Taylor协同算法推广到三维空间的可行性。

In order to accurately locate the leakage points of boiler tubes and make the power plant operating safe-ly,a location algorithm based on Chan and Taylor algorithms which are used in cellar net is extended to three-di-mensional location. Acoustic sensors arranged in the power plant are simulated to analyze the performance of the cooperative location algorithm by computer. The influence of the algorithm and Chan algorithm in performance are annlyzed and compared in different root-mean-square error of time difference of arrival (TDOA),positions of leak points and quantity of acoustic sensors. The conclusions of simulation show that the performance of cooperative al-gorithm is better than Chan algorithm in three-dimensional location and different positions of acoustic sensors can al-so influence the location algorithms. Therefore,Chan-Taylor location algorithm used in three-dimensional location is feasible.
