摘要
船舶电力系统容量小,在受到较大扰动时,频率和电压不再保持为恒定,而是一个动态变化的过程。为了对船舶电力系统的过渡过程进行分析,本文利用PSCAD/EMTDC软件建立了柴油机及其调速系统以及发电机励磁系统的数学仿真模型,并对其各组成部分进行详细分析。最后利用分级突加突卸负载的方式对机组模型的正确性进行验证,指出通过对船舶电站同步发电机的励磁控制和柴油机的转速控制可以提高船舶电力系统稳定性。
The capability of marine electric power system is low. When it comes under large disturbance, the voltage and frequency of the system is a dynamic process instead of keeping constant. In order to analyse the transition process of the marine electric power system, this paper use PSCAD/EMTDC to establish a simulation model of the diesel and its speed-governing system and the generator excitation system. It also analyses the component of the marine diesel generator simulation model. Finally, it uses the method of adding and discharging loads suddenly to validate the correctness of the model, and points out that it can improve the stability of the marine electric power system through the controlling of speed and excitation.
