摘要
船舶电力推进系统的大功率非线性负载会产生显著的谐波电流,并造成电网电压波形畸变。该文以某型测量船的电力推进系统为例,应用ETAP软件建立仿真模型,并进行谐波分析计算。仿真结果表明:该测量船在各种典型工况下的电压总谐波畸变率在规定范围内,可为今后相似船舶的谐波处理提供参考和借鉴。
The high-power nonlinear load of the marine electric propulsion system will generate significant harmonic currents and cause grid voltage waveform distortion.The Electrical Transient Analyzer Program (ETAP) is used to establish the simulation model of the electric propulsion system of a survey ship,and perform the harmonic analysis and calculation.The simulation results show that the total harmonic distortion rates of the voltage are all within the specified range for the ship under various typical operating conditions.It can provide references for the harmonic processing of similar ships in the future.
