Abstract

The aim of the paper is to present some particularities of the electricity quality on board ships. The specific vulnerability of the naval power systems is given, first of all, by ship’s power plant and its finite character. Power generation systems on board ships have, in their structure, a significant number of static power converters: controlled rectifiers, DC sources, DC power converters, inverters, etc. whose powers reach the order of tens of MW, comparable to the power of a ship’s plant. The use of these devices in finite naval power plants, inevitably, produces a serious disturbance of the voltage and current waveforms, especially in the power consumer networks. The paper presents the theoretical framework of the problem as well as the results of measurements, which illustrate the presence of the disturbing harmonics due to the static converters.

船舶动力系统电能质量评价
本文的目的是介绍船上电力质量的一些特点。舰船动力装置的有限性是舰船动力系统脆弱性的主要原因。船上发电系统在其结构中有相当数量的静态变流器:可控整流器、直流电源、直流电源变流器、逆变器等,其功率可达几十兆瓦量级,相当于一艘船的发电厂的功率。在有限的舰船动力装置中使用这些装置,不可避免地会产生严重的电压和电流波形干扰,特别是在电力消费网络中。本文给出了该问题的理论框架和测量结果,说明了静态变流器引起的干扰谐波的存在。
