An Empirical Study of Synchrophasor Communication Delay in a Utility TCP/IP Network

摘要: The strain on modern electrical power system operation has led to an ever increasing utilization of new Information Communication Technology (ICT) systems enhance the reliability and efficiency grid operation. Among these proposals, Phasor Measurement Unit (PMU)-based Wide-Area Monitoring Control (WAMC) have been recognized as one enablers “Smart Grid”, particularly at transmission level, due their capability improve real-time situational awareness grid. These differ from conventional Supervisory And Data Acquisition (SCADA) in that they provide globally synchronized measurements high resolutions. On other hand, WAMC also impose several stringent requirements underlying ICT systems, including performance, security, availability, etc. As a result, functionality applications is heavily, but not exclusively, dependent capabilities systems. This tight coupling makes it difficult fully exploit benefits synchrophasor technology without proper design configuration support applications. applications.In response above challenges, this thesis addresses dependence Specifically, two data quality attributes, latency completeness, are examined together with effects typical application, PMU-based wide-area damping outcomes research include quantified results form PMU communication delays frame losses, probability distributions can model delays. Moreover, determined for three different delay-robust designs application validated based results. Finally, virtual developed perform network co-simulations.The reported by offer prospect better predictions performance supporting terms completeness. be further used optimize integrated manner. contributes systematic approach considering PMU, part co-simulation platform, provides means investigate cost-efficient
