在当前各个核电厂中,随着核电厂数字化、信息化程度日益提升,对信号处理的可靠性和准确性要求越来越高。而所采集到的模拟输入信号,一般均含有各种噪声和干扰。本文主要通过在模拟信号离散化后进行数字化滤波,对比分析一些典型数字滤波算法对电厂模拟仿真带噪声数据的处理结果,总结典型算法对核电厂不同种类信号、不同类型的干扰采用的数字滤波方法的效果,对核电厂的信号处理算法选择起到一定的帮助和指导。
In the current various nuclear power plants, with the digitization of nuclear power plants, the increasing degree of information technology, the reliability and accuracy of signal processing requirements are getting higher and higher. The collected analog input signals generally contain a variety of noise and interference. In this paper, digital filtering is carried out after the discretization of the analog signal, and some typical digital filtering algorithms are compared and analyzed to deal with the noise data of power plant simulation. The typical algorithms are used to filter the different types of signals and different types of interference in the nuclear power plant. The effect of nuclear power plant signal processing algorithms to play a certain help and guidance.
