Abstract

The authors conduct the examination of power exchange fluctuations existence problem between the parallel running generators of the marine electrical complex. This article provides a new solution of a relevant problem of increasing the technical and economic efficiency of parallel synchronous generators operation of the marine electrical complex, which shows the rationality and efficiency improvement of their management systems in order to reduce the amplitude of power exchange fluctuations. The experimental results obtained in the form of waveforms for all modes of operation of the existing sea-ferry vessel “Eysk”, confirming the presence of the exchange and in-phase oscillation with an amplitude up to 100%, represents the presence of problems and lacks of parallel operation mode used in the ship's synchronous generator units. A method which could be applied to reduce power exchange oscillation amplitude lies in changing the settings of automatic diesel speed controllers. The expediency of adaptive self-adjusting automatic control system for the implementation of this method is explained as this article follows with the research results confirmed by mathematical modeling.

消除船舶电气系统中可交换功率波动方法的发展

对船舶电力系统并联发电机之间的电力交换波动存在问题进行了研究。本文针对提高并联式同步发电机运行的技术经济效益这一相关问题，提出了一种新的解决方案，说明了并联式同步发电机管理系统的合理性和有效性，以减小电力交换波动的幅度。现有海轮渡船“Eysk”的所有运行模式的波形形式的实验结果，证实了交换和同相振荡的存在，振幅高达100%，代表了问题的存在和缺乏并行运行模式在船上的同步发电机组使用。一种减小功率交换振荡幅度的方法是改变柴油机自动调速控制器的设置。本文说明了自适应自调节自动控制系统实现该方法的方便性，并通过数学建模验证了研究结果。
