摘要
基于全球定位系统GPS的同步相量量测单元PMU(Phasor Measurement Unit)是一种新型的量测装置,该装置可以直接量测节点电压相量。文章在电力系统同调性概念的基础上,通过数字仿真获取发电机的时间响应曲线,定义了基于相关性原理的发电机同调指标。该方法简明且易于实现,具有较高的应用价值。通过IEEE39节点对该方法进行了验证。
The synchronous phasor measurement unit(PMU) based on global positioning system(GPS) which can directly measure the nodal voltage phasors is a new type of measurement device.According to the power system coherency and the swing curves of the disturbed generators,apply the data mining and the principle of the correlation,define the indicator for coherence.The technique presented is simple and easy to realize and have the high application value.It is validated by IEEE39.
