摘　　要：针对船舶电力系统运行工况的复杂性和运行环境的特殊性所造成的电力参数测量精确度不高的问题,利用汉宁窗加权的递推DFT算法对电力参数进行分析和研究。从理论上分析了算法的可行性,通过仿真得到了较高的测量精度。经由嵌入式STM32F407和AD7656的综合设计,完成了一种船舶电力参数测量仪的研制,并结合电能质量谐波检测进行实验,利用标准信号源对测量仪的精度进行了测试。测试结果表明,设计的船舶电力参数测量仪检测精度高,可以应用于实际电力系统的参数测量。With the complexity and particularity of ship power system's operating environment,measuring deviceis designed to improve the accuracy. The Hanning window weighted recursive DFT algorithm is used to analyze the electrical parameters. The theoretical analysis proves the feasibility of the algorithm. Higher accuracy is got by simulation.Through the embedded STM32F407 and AD7656 integrated design,the development of a marine power parameter measuring instrument is completed. Combining with a standard signal source for precision measuring instruments,the power quality harmonic detection experiments are completed. Test results show that the designed instrument for measuring ship power parameters has high detecting accuracy and it can be applied in measuring parameters in the practical power system.
