Improved P-type synchrophasor model based on IEEE C37.118.1 reference architecture

Traditional wide area measurement systems (WAMSs) are incapable of effectively monitoring system stability in real time. System stability has now become an important requirement in modern renewable rich electricity networks. "Synchrophasor Technology" is an emerging WAMS technology which would enable time synchronized monitoring and reporting, hence can monitor system stability effectively in real time. The IEEE std. C37.118.1 TM stipulates the performance requirements which should be adhered by the synchrophasor units or phasor measurement units (PMUs). Based on the guidelines provided in the IEEE std. C37.118.1 TM, it is possible to develop an improved reference synchrophasor model which would provide improved reliability and stability. This paper analyses the feasibility and implementation of the improvements focusing on the P-Type (Protection) synchrophasor model. Results show that dynamic compliance is largely improved whilst the steady-state error margin is also reduced with the proposed synchrophasor model.
