为了研究影响PLC中压载波通信速率的主要因素——信噪,在深入了解中压信道特性以及分析现有解决方案OFDM利弊的基础上,通过选取代表性强的,由若干开关站、变电亭和环网箱构成的测试环境,获取载波组网具有可比性的测试数据,来对信噪产生的影响进行分析并介绍测试结果。测试结果的分析可以为我们配置最佳的载波输出频率提供有力的依据,为大幅提升载波通信的速率夯实基础
In order to study the influence of signal-to-noise, which is the main factor affecting the communication rate of PLC in ballast, based on the deep understanding of medium-voltage channel characteristics and the analysis of the advantages and disadvantages of the existing OFDM solutions, by selecting representative strong switchgears, Kiosks and ring cage form the test environment, access to carrier network with comparable test data to analyze the impact of signal noise and introduce the test results. The analysis of the test results provides a strong basis for us to configure the best carrier output frequency, laying a solid foundation for dramatically increasing the carrier communication rate
