چکیده
Power systems are extraordinary dynamic and complicated systems with various components and tools of generation, transmission, distribution, protection and control to guarantee the nation-wide interconnected grid's daily operation and safety. This paper reviews the latest Phasor Measurement Unit (PMU) technology development and applications in power system dynamic analysis and reduced model parameter estimation, event and fault location, and novel control strategies and algorithms employed in validating relay operations to prevent cascading failure. The methods and algorithms in the reviewed works are all in accordance with NERC recommendations and fit well in the new trend of wide-area protection and control. The reviewed technology can be utilized and combined in the future to address power system online dynamic simulation, control and protection. Key-Words: PMU, real-time data, fault diagnosis, event tree analysis, self-healing grid, cascading failure.
