abstract
2019 IEEE. Currently, there are over 2500 phasor measurement units (PMUs) installed in the East, West, and Texas interconnections in the USA, enabling wide-area situational awareness. One of the major concerns in industry is the susceptibility of synchrophasor systems to timing intrusion (TI) attacks. As examples, such TIs may result from compromised timing signal received from Global Positioning System (GPS), malicious attacks associated with the time stamp assigned to the PMU streaming values, or induced latency or other disruptions in the transmission of synchrophasor frames. TI attacks may invalidate measurements of key electrical quantities, and may consequently incapacitate vital control functions. In order to provide a solution to TI detection and mitigation, a TI management testbed is implemented to evaluate the resilience of synchrophasor systems against TI attacks. The functional specifications, implementation details of the TI evaluation testbed, as well as associated testing tools are introduced and discussed. Initial test use cases are defined, the results are presented, and future developments are outlined.
