舰船电网是具有各类负载和变电装置的移动式独立电网。首先提出在舰船照明电网中应用电力线载波通信技术（Power Line Communication），具有信道谐波干扰少、负载简单、脉冲噪声可评估，分布广的优势。而后在考虑趋肤效应的影响下分析计算出包括交流电阻、交流电感和相间电容在内的照明电缆参数，根据传输线理论得出舰船照明电网电力线信道特性阻抗、输入阻抗与频率的关系，实现电力载波调制解调器耦合电路与舰船照明电缆线的两种匹配：一是发射端的共轭匹配，使发射功率最大；二是负载端的阻抗匹配，使接收功率最大。同时给出了适用于舰船电网的电力载波耦合电器的阻抗设计参数。

Shipboard electric network is an independent mobile electric network with all forms of loads and power transformation devices. This paper proposes the power line carrier (PLC) application to shipboard lighting network in the first place, because lighting network is of less harmonic wave, simple load, accessible pulse noise and widespread distribution. Considering the skin effect, we calculate the lighting cable parameters including AC resistance, AC inductance and line-to-line capacitance. The relation between the frequency and the characteristic impedance and input resistance is deduced according to the Microwave Transmission Theory. And we can realize two kinds of impedance matching between PLC coupling circuit and lighting cable: one is conjugate match in transmitting terminal, which can achieve maximum transmitted power;the other is impedance match in loading terminal, which can achieve maximum received power. At the same time, we give the parameter design of the coupling circuit suitable for shipboard electric network.
