摘　　要：针对船舶电站准同步并车的要求以及特点,设计高精度新型数字同步表。以Proteus和Keil为实验平台,完成了相应的软件编程和外围硬件电路的设计,分析了主要技术环节的实现。仿真实验结果表明新型数字同步表的设计完全实现了针对待并发电机和电网电压的频差和相位差的检测与显示功能,且运行可靠,检测精度高,成本低。According to the requirements and characteristics of automatic control of ship＇s power station, the new high-precision digital synchronoscope is designed. Using Proteus and Keil as experimental platform, the corresponding design of software programming and peripheral hardware circuits are completed, and the realization of main technology is analyzed. Simulation results show that the design of new digital synchronization table makes sure that the frequency difference and phase difference of generators and grid voltage can be detected during generator connecting in parallel with system, and it operates reliably with high precision.
