“…In this respect, the emergence of the wide area measurement system provides a new idea for the design of power system protection systems. The first wide-area protection principle is derived from the transient based protection in 1996 [2], in which GPS time synchronization played a major role in the design [3]. This was immediately followed by a summary paper in 1997, which systematically outlines the concept of the so-called "wide area protection" [4], focusing principally on the control aspect of the area.…”

“…This led to the development of the so-called 'transient based protection' relays based on travelling wave and superimposed components, which utilizes the fault generated transients for transmission system protection. Studies have found that the fault generated high frequency transients can be detected and quantified, creating the possibility for developing new protection principles and techniques [2]. Considerable effort has now been devoted to research on high frequency transient detection.…”

Synchronized wide area communication has become a mature technology, which makes the real-time interaction between the substations and the wide area protection and control system possible. However, the present protection and control system to handle this real-time data has been recognized to be deficient. This paper begins by reviewing the development history of power system protection, with special attention paid to the recent development in the field of wide-area and integrated protections, in order to look into the future development of protection and control systems. Then the concept of integrated wide area protection and control is introduced, where it can be shown that a hierarchical protection and control system provides the protection and control for wide area or regional power substations/plants and their associated power networks. The system is mainly divided into three levels: the local, the substation/plant, and the wide area/regional. The integrated functions at each level are described in details with an aim to develop an optimal coordination mechanism between each level. The key element in the proposed system is the wide area real-time protection and control information platform, which not only enables the merger of three lines of defence for power system protection and control, but also provides a perfect tool for the application of cloud computing in substations and power networks.

“…The fast development in both microprocessor and transducer technologies in recent years has enabled fault detection techniques to be considered which were impractical in the past and encouraged interest in the utilization of fault generated transients for protection. Studies have found that the fault generated high frequency transients can be detected and quantified and open the possibility for developing new protection principles and techniques [2][3][4][5][6]. At the same time, the dramatic growth in signal processing power of relay platforms, and the availability of suitable communication schemes, has provided a new opportunity to revisit the concept of integrated protection [7].…”

“…However, there are numerous existing and potential high-frequency applications for signal transmission on power cables, as e.g., with power line communication (PLC) techniques [28], simulation and analysis of lightning and switching overvoltages [28], transient based protection [2] and fault localization and Partial Discharge (PD) monitoring [24,29,32]. The present study is motivated in particular by the potential of improving the fault localization and diagnosis techniques for High-Voltage Direct Current (HVDC) submarine power cables based on detection and analysis of transient (virgin) pulses caused by dielectric breakdown.…”
