“…Moreover, the accuracy of an FL can be improved by applying synchronized measurements of currents or voltages. Until now, many faults have been detected by PMUs in distribution systems [72][73][74][75][76][77][78]. However, some FL methods use only current or voltage phasors [79,80].…”

Synchrophasor technology opens a new window for power system observability. Phasor measurement units (PMUs) are able to provide synchronized and accurate data such as frequency, voltage and current phasors, vibration, and temperature for power systems. Thus, the utilization of PMUs has become quite important in the fast monitoring, protection, and even the control of new and complicated distribution systems. However, data quality and communication are the main concerns for synchrophasor applications. This study presents a comprehensive survey on wide-area monitoring systems (WAMSs), PMUs, data quality, and communication requirements for the main applications of PMUs in a modern and smart distribution system with a variety of energy resources and loads. In addition, the main challenges for PMU applications as well as opportunities for the future use of this intelligent device in distribution systems will be presented in this paper.

“…Therefore the quality of synchrophasor measurements from PMUs, including timing accuracy, has also been a key topic of research, particularly in Europe [7] and the USA [8], [9]. Research work has highlighted the challenges associated with: measurement quality, which is very important for distribution system applications of PMUs; PMU data quality; PMU timing accuracy [10]; real-time supervisory assessment of multiple PMU data streams [11]; and latency [12]. The importance of rigorous testing of PMU-based systems is strongly emphasized in [13] and analysis of the large-scale PMU data quality issues is given in [14].…”

Due to the changing nature of power systemswith reduced electrical inertia and the prevalence of smaller controllable power resources rather than large generatorsnew control approaches are required to mitigate disturbances. Ubiquitous measurements and communications networks can be leveraged to accelerate and provide a targeted, real-time response in such future systems. However, autonomous control of power systems requires dependable measurements. This paper provides a review of state of the art approaches to real-time power system control using synchrophasor measurements. In particular, examples are given involving recent developments in frequency regulation. Through a case study, it is shown how laboratories can be linked using Software-Defined Networking technologies to conveniently share resources in order to realistically and comprehensively validate synchrophasor-based control systems.

“…PMUs are used to get the voltage and current measurements from different buses for approximating a voltage stability indicator in near real time. Some recent PMU based applications for voltage stability are summarized in Table 3 [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52].…”

“…In second, PMU data is analyzed for most prominent disturbance signature. PMU data is fed to the strongest signal selection and fault detection (SSFD) module which preprocesses the signals by removing bad data and identify the data stream with the highest strength [48,49] An adaptive PMU based protection scheme for both transposed and untransposed parallel transmission lines which is based on the distributed line model and the synchronized phasor measurements at both ends of lines is discussed [50] Another adaptive wide area backup protection scheme for transmission lines is proposed in which backup protection zones are formed based on PMU placement and network topology. It also provides a non-iterative solution for the faulted line and FL identification problem [51,52] SSE estimates the PS state associated with a given time and based on the measurement set corresponding to that moment of time.…”

Synchrophasors are time-synchronized electrical measurements that represent both the magnitude and phase angle of the electrical sinusoids. Synchrophasors are measured by fast time-stamped devices called phasor measurement units (PMUs) to constitute the basis of realtime monitoring and control actions in the electric grid. Due to its enhanced situational awareness capabilities, many applications of PMUs are presented in the literature in the past decades. This paper presents a comprehensive summary of synchrophasor technology, its architecture, optimal placement techniques and its applications in electric power transmission and distribution systems. These applications include wide-area situational awareness and monitoring, state estimation, fault location and protective relaying, islanding detection etc. This review also covers some of the existing challenges in its implementation and its potential applications.
