With the development of technology in the power field gradually becoming digital and automated, technologies such as cloud computing and big data are gradually applied to sense and control the power grid. However, accurate sensing and measurement of the grid state is the main technical basis for data analysis and automated operation and maintenance. Therefore, this paper proposes a multi-point synchronous phase measurement method based on non-contact microsensors to address the shortcomings of existing grid sensors in terms of sensing accuracy and timeliness. The method solves the synchronous phase measurement problem of grid PMUs by deploying non-contact TMR sensors to achieve single-axis current measurement. And based on this, the multi-point synchronous phase measurement method is improved and designed to solve the theoretical accuracy error caused by wire eccentricity. Meanwhile, it is combined with the dynamic phase measurement method to characterize the synchronous phase change and represent the dynamic characteristics of the grid signal more accurately. The simulation results of the experimental platform show that the measurement error size of the multi-point synchronous phase measurement method is within 4%. Moreover, its phase angle measurement error is less than 0.25 degrees, which can realize the synchronous phase measurement of non-contact sensors. It not only reduces the measurement error caused by the environment, but also makes the measurement more convenient and faster, promotes the digital development of the power grid, and provides great convenience for the fault detection and operation and maintenance of power equipment.

“…• small angles of difference on the distribution lines of the order of tenths of a degree; • the presence of noise in the measurements of the distribution circuits, linked both to the randomness of the loads and to the presence of a greater harmonic spectrum caused by the great diffusion of electronic converters; • the costs of the PMUs if referred to transmission systems are reduced thanks to the size of the system, while in distribution systems due to the proximity of the nodes they increase; • the adoption of a low-cost, very efficient and reliable monitored data communication system. In distribution systems, therefore, different applications have been developed called D-PMUs or microPMUs which have better performance in terms of resolution and measurement precision and a lower construction cost than the PMUs used in transmission systems [26,27]. Furthermore, the greater interest in the analysis of the distribution system with the increasing penetration of distributed production from RES and the opening of the liberalized energy markets contribute to the study and research of PMUs [26].…”

In recent years, power grid infrastructure has moved from a centralized power generation model to a paradigm in which generation capacity is distributed across an increasing number of small power plants that rely on renewable energy sources. Systems for emerging distribution systems need a very new protection paradigm, architecture and philosophy making use of new protection devices and sensors such as digital relays, phasor measurement units (PMUs), smart reclosers and line sensors. This article examines the application of PMUs in smart distribution grids and from the point of view of prosumers.

“…The gradual introduction of PMUs according to the works [5,6], in addition to assessing the state of the network, allows us to solve the following tasks: the verification of the dynamic models of power systems, the monitoring of intersystem power fluctuations and a search for their sources, the monitoring of the maximum permissible power flows over controlled sections and an assessment of stability reserves, the identification of emergency situations and the localization of damage, the monitoring of asymmetric modes, the verification of the parameters of replacement circuits of system elements, the development of a new generation of automatic control systems, etc. As can be seen, considerable attention is paid to the tasks of analyzing transients.…”

The development of modern power systems is directly related to changes in the traditional principles of management, planning, and monitoring of electrical modes. The mass introduction of renewable energy sources and control devices based on power electronics components contributes to changing the nature of the flow of transient and quasi-established electrical modes. In this area, the problem arises of conducting a more accurate and rapid assessment of the parameters of the electrical regime using synchronized vector measurement devices. The paper presents an extensive meta-analysis of the modern applications of phasor measurement units (PMUs) for monitoring, emergency management and protection of power systems. As a result, promising research directions, the advantages and disadvantages of the existing approaches to emergency management, condition assessment, and relay protection based on PMUs are identified.
