| Abstract: |
| Real time monitoring and control of a modern power system has achieved significant development since the
incorporation of the phasor measurement unit (PMU). Due to the time-synchronized capabilities, PMU has increased
the situational awareness (SA) in a wide area measurement system (WAMS). Operator SA depends on the data
pertaining to the real-time health of the grid. This is measured by PMUs and is accessible for data analytics at the
data monitoring station referred to as the phasor data concentrator (PDC). Availability of the communication
system and communication delay are two of the decisive factors governing the operator SA. This paper presents a
pragmatic metric to assess the operator SA and ensure optimal locations for the placement of PMUs, PDC, and the
underlying communication infrastructure to increase the efficacy of operator SA. The uses of digital elevation model
(DEM) data of the surface topography to determine the optimal locations for the placement of the PMU, and the
microwave technology for communicating synchrophasor data is another important contribution carried out in this
paper. The practical power grid system of Bihar in India is considered as a case study, and extensive simulation
results and analysis are presented for validating the proposed methodology. |
