摘要
在半潜船的改装项目中,通过新加可变频调速的变频器控制压载泵可实现船舶的下潜和上浮,但随之产生的谐波对电网产生了危害,文章通过治理谐波的实践经验,以“海燕”油船改装为半潜船为例,对新加变频器产生谐波的影响及治理进行了分析,为类似船舶的谐波改善提供了参考。
In the semi-submersible ship modification project, the ballast pump can be controlled by the newly added variable frequency and speed adjustable frequency converter to realize the ship’s diving and floating, but the resulting harmonics have harmed the power grid. The practical experience of harmonics, taking the "Haiyan" tanker converted into a semi-submersible vessel as an example, the influence and treatment of harmonics generated by the newly added frequency converter are analyzed, which provides a reference for the improvement of harmonics of similar ships.
