摘　　要：相量测量单元(PMU)相量数据有效性的关键在于时间同步。但由于遵循的标准不同,导致一致性和交互性差。文中根据IEEEStd1344—1995(R2001)和IEEEStdC37.118—2005这2个新旧标准,通过比较对PMU的一些关键问题进行了讨论,包括同步相量、时标和传输频率等,并对这些概念的实现和使用提出了解决方案。同时,根据综合矢量误差提出对PMU的静态测量精度和动态响应性能的评价方法及误差计算方法。最后对数据传输格式的改进进行了分析。The key of the data validity oi the phasor measurement unit （PMU） is the synchronization. The difference in the applied standards can cause to relatively bad consistency and interoperation. According to the comparison of the old and new IEEE synchrophasor standards, IEEE Std 1344-1995 （R2001） and IEEE Std C37. 118-2005, such key problems are discussed as synchrophasor, time tag and reporting rate etc. Resolving schemes for the realization and application of these problems are also proposed. According to total vector error （TVE）, the evaluation and error calculation methods for the static measurement precision and dynamic response characteristics of PMU are giyen. The improvement of the data transmission format is finally analyzed.
