Introduction

The history of phasor measurement unit (PMU) evolution was discussed in Chapter  1. In this chapter we will consider certain practical implementation aspects of the PMUs and the architecture of the data collection and management system necessary for efficient utilization of the data provided by the PMUs. One of the most important features of the PMU technology is that the measurements are time-stamped with high precision at the source, so that the data transmission speed is no longer a critical parameter in making use of this data. All PMU measurements with the same time-stamp are used to infer the state of the power system at the instant defined by the time-stamp. It is clear that PMU data could arrive at a central location at different times depending upon the propagation delays of the communication channel in use. The time-tags associated with the phasor data provide an indexing tool which helps create a coherent picture of the power system out of such data. The Global...
