摘要
电力推进系统是舰船重要的动力系统,其负荷量占全船负荷量4/5左右。在电力推进系统运行中,会对舰船电网产生一定程度功率因数影响和谐波干扰,降低电网运行的安全性。为有效控制功率因数和谐波干扰,要采用高压整流技术,此项技术能够降低谐波电流,使电力推进系统保持更加理想的机动性和工作性能。本文从分析高压整流技术控制策略入手,提出高压整流技术在舰船电力推进系统中的具体应用方案,通过仿真实验证实本文提出的高压整流控制系统能够有效抑制谐波污染。
The ship’s electric propulsion system is an important power system of the ship,and its load accounts for about four-fifths of the ship’s load.In the operation of the electric propulsion system,it will have a certain degree of power factor influence and harmonic interference to the ship’s power grid,reducing the safety of the power grid operation.In order to effectively control the power factor and harmonic interference,high-voltage rectification technology should be adopted.This technology can reduce the harmonic current and make the electric propulsion system maintain more ideal mobility and working performance.This paper starts with analyzing the control strategy of high-voltage rectification technology,and proposes a specific application scheme of high-voltage rectification technology in the ship’s electric propulsion system.Simulation experiments prove that the high-voltage rectification control system proposed in this paper can effectively suppress harmonic pollution.
