高频电晕杂音的微型机统计观测

本文讨论了影响超高压线上载波电话通信的电晕杂音,并提出实现微型机实线统计观测和数据处理的方法。介绍对电晕杂音的采样和四种气候的数据文件,以及计算电晕杂音的均值、方差、直方图、分布曲线、拟合优度检验、信杂比统计分析和非线性回归的方法及其应用软件。统计检测系统共检测和计算六条线路36个数据。计算结果可为经济、合理、可靠地设计载波通信的收、发信电平提供准确的数据。

A Statistical Observation on High Frequency Corona Noise by Microcomputer

Discusses the corona noise which disturbs the carrier telephone communi-cation via the extra- high- voltage power line, and offers a method to implementthe real- line statistical observation on corona noise by microcomputer and thedata processing managment proper. Describes the sampling method of coronanoise and the constraction of data file corresponding to four kinds of local cli-mate. Methods and its application software for the calculations of means,varia-nces, histograms and distribution curves of corona noise and for the goodnessof fit test, S/N ratio analysis and non- linear regression, etc., are presented .The-re are 6 lines and 36 data detected and calculated by the statistical detectionsystem. The results make provision for the design of electric levels for receivi-ng and transmitting signals in carrier communication via power-line, with ec-onomy, reasonability and reliability.
