Research on Application of Synchronized Phasor Measurement Unit (PMU) for Smart Substation
Synchronized phasor measurement unit (PMU) has become the important monitoring device in power networks for high precision and accurate time tag of measurement data. This paper presents the PMUs suitable for smart substation which adopt embedded software-hardware platform. The differences between the common PMUs and PMUs for smart substation are introduced, and the software modules design is put forward, too. The key technology of PMUS is introduced including receiving and processing of sampling data message based on IEC 61850 standard and phasor calculation based on discrete Fourier transform.
