摘要
目前电网中负载传导骚扰测量与门限值标准都基于传统的混合模方式,包含共模和差模骚扰。电力线载波通信系统中,信号通常以差模方式进行传输,共模骚扰能够得到有效抑制,而电网负载中差模骚扰是影响电力线载波通信性能的主要因素之一。提出了一种基于电力线载波通信耦合装置的差模传导骚扰测试方法,该电力线耦合装置能够有效地对共模信号进行抑制,对差模信号进行提取。测量并研究了不同类型家用电器的差模骚扰特性,对比分析了所提出的差模骚扰和传统混合模骚扰测试结果。结果表明,差模传导骚扰相较于传统骚扰具有更大的骚扰幅值。所提出的测试方法能有效地对家用电器的差模传导骚扰进行测试,为建立电力线差模传导骚扰限制标准提供理论依据和实验手段。
A new method of differential mode conducted emission for power line communication is presented in this paper.In the conventional conducted emission measurement,the interference signal is measured in a mixed mode,including common mode and differential mode.However,in the power line communication the signal is transmitted in differential mode and household appliances as well as other power equipment bring extremely high differential mode interference.The differential mode conducted emission measurement on household appliances become very important for power line communication.The household appliances conducted interference are classified into two groups,and the proposed measurement results are compared with the conventional measurement.From the measurement results,it is shown that in most cases,differential mode conducted emission interference level is higher than common mode conducted emission interference.
