针对当前船舶配电网扰动信号检测系统存在的检测精度低、检测时间长等不足,提出了基于数学形态学的船舶配电网扰动信号分形检测系统。首先对当前船舶配电网扰动信号检测系统的工作原理进行分析,指出引起目前系统不足的原因,然后采用数学形态学对船舶配电网扰动信号进行滤波处理,对船舶配电网扰动信号中的噪声进行去除和抑制,最后采用分形理论对船舶配电网扰动信号进行检测和定位,并实现了船舶配电网扰动信号检测的仿真验证性测试。测试结果表明,本文检测系统可以对船舶配电网扰动信号进行高精度定位,具有很强的自适应能力,缩短了船舶配电网扰动信号检测时间,是一种速度快、精度高的船舶配电网扰动信号检测系统。

In view of the shortcomings of the current detection system of ship distribution network disturbance signals,such as low detection accuracy and long detection time, a fractal detection system of ship distribution network disturbance signals based on mathematical morphology is proposed. Firstly, the working principle of the current disturbance signal detection system of ship distribution network is analyzed, and the reasons for the shortage of the system are pointed out. Then, the disturbance signal of ship distribution network is filtered by mathematical morphology, and the noise in the disturbance signal of ship distribution network is removed and suppressed. Finally, the disturbance signal of ship distribution network is detected and located by fractal theory. The simulation validation test of disturbance signal detection in ship distribution network is realized. The test results show that the detection system in this paper can locate the disturbance signal of ship distribution network with high precision, has strong adaptive ability, shortens the detection time of disturbance signal of ship distribution network, and is a fast and high precision disturbance signal detection system of ship distribution network.
