【摘要】 宽带电力线通信(BPLC)利用现有的电力网作为高速数据传输媒介时,存在屏蔽性差、阻抗不匹配、载波频率与短波无线电频段重叠等问题,由此而引发的电磁干扰成为BPLC普及与推广的最大障碍,同时也给BPLC商业化提出了更高的电磁兼容要求。本文探讨了宽带电力线通信中可能存在的电磁干扰问题以及电磁辐射的测量方法,并提出了改善BPLC系统电磁兼容性的措施。更多还原

【Abstract】 In broad-band power line communication(BPLC), electric power network works at a high speed data transmission medium which shield the function badly,impedance miss match and carrier frequency mix with HF frequency band.EMI’s problems that BPLC causing become the biggest obstacle of BPLC development,and EMC requirements are needed for BPLC commercialization.The EMI problems in BPLC are discussed,and the measuring methods of electromagnetism radiation are analyzed.Several solutions to prove EMC of BPLC are provided.更多还原
