| 摘要: |
| 实现了一种新型的同步测量系统，在以太网通信的基础上，引入了ZigBee无线网络通信方式，保证了在不便布置有线网络的场所，系统的信息交互能够正常进行。同时对IEEE C37.118进行扩展，引入IEC 61588的主要算法，在以太网中实现了高精度的时钟同步。系统采用了分布式体系结构设计，相量测量的幅值误差小于0.5 %，相位误差小于1°。10节点SPMU子网测试表明：瞬时相量算法时延为77.36 μs，网络传播路径时延为37.02 μs。 |

| Abstract: |
| A scheme of synchronous measuring system is introduced，which，besides the Ethernet network communication，adopts ZigBee wireless network communication to ensure the system information exchange for areas where the network cable laying is impossible. It applies the distributed system architecture and the main algorithms of IEC61588 to extend IEEEC37.118 for high-precision clock synchronization，with phasor measurement error less than 0.5 % and phase measurement error less than 1°. Test results for the 10-bus SPMU subnet show that：the time delay of instantaneous phasor measuring algorithm is 77.36 μs and that of network transmission path is 37.02 μs. |
