摘要
随着中国经济的飞速增长,航运行业也得到蓬勃发展。而随着船舶的大型化,自身电力系统容量越来越大,电网也越加密集,并且船舶航行也不是在稳定环境下进行,海水侵蚀比较严重,从而电力系统的绝缘故障频率较高,对绝缘故障点的迅速定位就特别重要。本文在研究了现代绝缘监测系统技术基础上,提出了一种单频信号绝缘监测技术,通过对传统双频信号监测技术的改进,简化了系统电路与软件复杂度。最后设计了基于DSP的在线监测系统装置,验证了系统的有效性。
With the rapid growth economy of china,shipping industry also has developed rapidly.With the ship become more and more large,the capacity of power system must be bigger and the grid be more intensive. And the environment of ship is so bad,water erosion is always there,the insulation fault of power system often happens,so how to monitor the insulation fault become important. This paper research the insulation monitoring technology,propose single frequency signal insulation monitoring way. At last,design online insulation monitoring system based on DSP.
