摘　　要：针对新能源并网、高压直流输电存在的宽频振荡问题,以同步相量测量装置(PMU)为基础,将宽频测量结果纳入广域同步测量系统(WAMS)势在必行。为实现宽频测量结果的实时传输,分析了现行的主子站同步相量通信规约,并在此基础上提出两种不同的宽频测量规约扩展方案,并从数据传输带宽、工程改造和可扩展性等方面对两种方案进行了分析,旨为PMU装置宽频测量传输规约的制定和完善提供基础支撑。The new energy grid connection and HVDC transmission have the problem of wide-range-frequency oscillations,so it is imper-ative to incorporate wide-frequency measurement results into the Wide Area Measurement System(WAMS)based on the Phasor Measure-ment Unit(PMU).To realize real-time transmission of wide-frequency measurement results,the paper analyzes the current synchronized pha-sor communication protocol of main stations and substations and proposes two different expansion schemes of wide-frequency measurement protocol.It makes analysis of two schemes from the aspects of data transmission bandwidth,engineering reconstruction and expandability to lay foundation for formulating and improving the wide-frequency measurement transmission protocol of PMU.
