“…In practice, CGGs are often defined based on operational experience (e.g., in [12]) or by observing the simulated rotor angle dynamics for multiple disturbances [31]. In some grids, the potential CGGs are obvious from the network structure [13], [33]. Eventually, it is possible to use a combination of multiple methods to define the CGGs.…”

With the growing number of severe system disturbances and blackouts around the world, controlled system separation is becoming an increasingly important system integrity protection scheme (SIPS) to save the electric power system from a complete or partial disintegration. A successful controlled splitting approach should at least tackle the following two well-known and interrelated problems: "when to split?" and "where to split?". Multiple previous publications consider these problems separately, and even those pursuing a combined approach propose solutions with limited applicability. In this article, we are proposing a novel PMU-based detector of loss of synchronism that utilizes generator PMU data to promptly detect rotor angle instabilities over a wide area. Moreover, we are showing how our loss of synchronism detection principle can be coupled with the known controlled splitting techniques to form an integrated defense scheme against unintentional loss of synchronism. The performance of this wide-area SIPS is demonstrated on the IEEE 39-bus test power system for various types of unstable conditions.

“…The North American Electric Reliability Corporation (NERC) concludes that synchrophasor technology has the potential to change the control room operational environment like no other technology since implementation of state estimator technology [1]. Over the years, to extract valuable information from synchrophasor data, many PMU-based applications have been developed [2][3][4][5]. Traditional SCADA based state estimation is complemented by synchrophasor data [2,3].…”

“…Advanced training simulators facilitate operator training [4]. Oscillation monitoring and wide-area damping controls are developed based on PMU data [3,5]. However, in line with the growth of these advanced phasor applications there are challenges for both power utilities and application developers in developing and evaluating such applications.…”

Wide Area Measurement Systems (WAMS) using phasor measurement unit (PMU) demonstrate the great potential in monitoring and analyzing power systems. Synchrophasor applications, such as system monitoring, wide-area controls, linear state estimation, and advanced training simulator, are developed to utilize valuable information from synchronized phasor data. However, there are challenges for both power utilities and application developers in designing, developing, testing and evaluating these applications. One of the main issues is the lack of a real-time simulation platform to emulate the PMU data that may be collected from WAMS. To help address these challenges, this paper proposes a software-based synchrophasor system emulator, ePMU. ePMU emulates synchrophasors by streaming real-time simulation results in standard PMU data format for large power system models. In addition, ePMU emulates actual power system controls by accepting commands from external applications to change network parameters and topologies during real-time simulations. This paper presents this real-time synchrophasors emulator and illustrates its values and benefits.
