| 摘 要： | 分析了模拟合并单元的采样值映射模型和实现方法，利用同步采样技术，将传统PTCT的模拟交流信号构建成符合IEC60044-7/8和IEC61850-9-1标准的采样值映射，从而在传统变电站的基础上直接奠定IEC61850标准的数据基础。提出并验证了模拟合并单元的测试方案。该模拟合并单元已在数个110 kV变电站数字化工程中得到了应用。

| Abstract: | The sampled value mapping model and realization method of Analog Merging Unit(AMU) is analyzed in this paper.By using synchronized sampling technology,Analog AC signals from traditional PTCT are constructed into a sampled value mapping which defined in IEC60044-7/8 and IEC61850-9-1.So the basic IEC61850 data is established for traditional substations.The test method for AMU is proposed and verified.The actual applications of the AMUs have been realized in several 100 kV substations digitalized engineering. |
