Measuring the Electric Grid

This book offers ideas on ways to make better, more useful measurements in an increasingly challenging power system environment. The technology for computing and communicating information has evolved almost beyond recognition since power systems got started, and it is time to pay attention to the possibilities now available by correct consideration of the theoretical aspects of measurement. The first four chapters expound on measurement theory, and present ideas that give a foundation for the second part of the book. In the next four chapters, important measurements that are specific to the power system are scrutinized closely. Particular light is shone on reactive power, and the phasor measurement unit. The final chapter outlines ideas for further work, and the book includes an appendix that covers the important topic of uncertainty in measurement.
