| 摘要: |
| 在介绍了利用相量法计算电力系统参数原理的基础上，给出基于高速和双串口中央处理器DS80C32的相量测量单元PMU(Phasor Measurement Unit)的系统硬件组成。PMU的同步时钟由全球定位系统GPS(Global Positioning System)提供。用此方法计算得到系统各节点的线路序参数，与传统线路参数测量方法的结果相比，具有测量精度更高、结果更准确的优点。 |

| Abstract: |
| The principle of phase measurementmethod for measuringpower system parameters is introduced and the system hardware construction of PMU(Phasor Measurement Unit)is given,which is based on high-speed CPU DS80C32with double serial ports.The synchronous clock of PMU is provided by GPS(Global Positioning System).Compared with traditional methods,the line parame-ters measured by this method for each node on power system are more accurate.The phasor mea-suring errors are analyzed and the solutions are suggested. |
