Abstract

Narrowband power-line communication seems to be a suitable communication technology designed for off-grid renewable energy solutions. Existing electrical installations can be designed both for the transmission of electricity and for the communication of electrical equipment operating inside such an installation. This study presents an implementation of the above-mentioned off-grid communication system and examines the basic problems related to its exploitation. The authors of this article focused their attention primarily on examining the disturbance of the communication channel caused by the use of typical electrical devices, such as: a light bulb, a kettle, etc. used in a household. The aim of the research was also to find the impact of switching on individual devices and their combinations on the disturbances during data transmission. Measurements of incorrectly transmitted data packets were carried out and then the test results were referred to the error measures. Moreover, the influence of the carrier frequencies on the signal attenuation and the method of eliminating the existing interferences were also discussed.

摘要

窄带电力线通信似乎是一种适用于离网可再生能源解决方案的通信技术。现有的电气装置既可以设计用于电力传输，也可以设计用于在该装置内运行的电气设备的通信。本研究介绍了上述离网通信系统的实现，并研究了与其开发相关的基本问题。本文的作者主要将注意力集中在研究由典型电气设备（如家庭中使用的灯泡、水壶等）的使用所引起的通信信道干扰上。该研究的目的还在于找出单个设备及其组合的开启对数据传输期间干扰的影响。对错误传输的数据包进行了测量，然后将测试结果与误差度量相关联。此外，还讨论了载波频率对信号衰减的影响以及消除现有干扰的方法。
