摘要

The phasor measurement unit has emerged as a complex, real-time measurement and control system necessitated by the modern power system, the most complex machinery. The extensive installation of phasor measurement units in recent times requires secure and reliable operation. The existing reliability models for phasor measurement unit reliability analysis are constrained by assumptions that disregard the inherent complexity, thus calling for the necessity of a system of systems engineering based reliability model for phasor measurement units. Such a system of systems engineering based model paves the way to accommodate different functional and logical relationships in a suitable way. Another major contribution of this article is the use of statistics of extremes to take into account the scarce failure data for phasor measurement units, which are recent in origin. The results reported in this article validate the efficacy of the system of systems engineering based reliability model.
