Reviews

“.. provides engineers, field technicians, electricians, and plant operators a better understanding of power system protection systems, and as such could be used for company onsite training as well as individual learning .. it is an outstanding resource for obtaining a quick overview of the basic fundamentals of protection systems commonly used in mainly low and medium voltage power systems.” — IEEE Electrical Insulation Magazine, 2006

Developments in the 1980s and 1990s provided new means to advance power system protection, especially the ‘Adaptive Protection’ and the Artificial Intelligence (AI)-based protection techniques proposed in the 1980s and 1990s. The adaptive protection started with the application of Inverse Definite Minimum Time Overcurrent (IDMT) protection in the early time of protection history. The concept played an important role in the 1980s with the progress of computing technology and associated control theory. It can be defined as a new type of relay protection which can change the performance, characteristics or set value according to the operation mode and fault condition of the power system. The basic idea of adaptive relay protection is to protect the power system as much as possible to improve the performance of the protection. Adaptive relay protection has the advantages of improving the response of the system, enhancing the reliability and improving the economic benefits. It has a wide application prospect in the field of distance protection, transformer protection, generator protection, autoreclosure and so on. Research has discovered that, to achieve the protection of the system adaptive to the operation mode and fault status, more detailed system operation and fault information are required through communication network.

The 1990s witnessed the rapid development of electronic and computer technology, the artificial intelligence technology such as artificial neural networks, genetic algorithms, evolutionary algorithm, fuzzy logic and other research applications, which have been applied to the field of relay protection. For example, artificial neural network (ANN) is used to achieve fault type identification, fault distance measurement, direction protection, and so on. Artificial neural network has the characteristics of distributed storage, parallel processing, self-organization and self-learning. The application of artificial intelligence will improve the speed and accuracy of fault detection and analysis, which represents the future development of an intelligent diagnosis system.

As a result of these developments, the performance of the protection relays has been improved. However, these developments have concentrated on the improvement of conventional relaying techniques, and no significant new relaying principles have been derived from the application of the Adaptive and AI techniques. At the same time in the 1990s, with the continuous expansion of the power network, the demand for fast fault clearance to improve system stability encouraged research into non-power system frequency fault detection techniques to increase the speed of the relay response. 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. Another important milestone is the application of novel communication technique, the utilization of global positioning system (GPS) in power system protection as shown in Fig. 1. In this respect, a number of new techniques has been proposed. In particular, the new proposed protection relay principle is able to provide protection for wide area power network [3, 4]. Following the development, the concept of wide area protection focusing on control aspect has been presented [5].

In recent years, the dramatic growth in signal processing capability of relay platforms, and the availability of suitable communications schemes, have provided a new opportunity to revisit the concept of centralized protection. Research [6] on the concept of ‘Integrated Protection’ shows that information obtained from multiple power plants and components can be used to derive new protection principles and schemes, which could have significant advantages over the existing protection techniques based on the individual plant or component. In this respect, the substation area protection [7] has quickly become a practical development and application area. Furthermore, the development of information technology has resulted in the interests in utilizing cloud computing [8] and big data techniques, as shown in Fig. 1, to improve the performance of power system protection and control.

On the other front, the developments in the field of substation integrated automation technology provide the technical basis for optimizing the combination and system integration of monitoring, control, protection and measurement device and system. The implementation of relay protection and integrated automation reflects in the integration and resource sharing, remote control and information sharing. Taking the remote terminal unit and microcomputer protection device as the core, the control, signal, measurement, billing and other circuits are integrated into the computer system to replace the traditional control protection cabinet, which can reduce the area and equipment investment and improve the reliability of the secondary system. With the advanced computer and communication network, the relay protection device is actually a high performance and multi-function computer, which is an intelligent terminal of the whole power system computer network.

It can obtain any information about the operation and fault of the power system from the network, and can transmit any information of the protected components to the network control center or any terminal. Therefore, each microcomputer protection device can complete not only the relay protection function, but also the measurement, control, data communication and other functions under normal operation condition, and can also realize the integration of protection, control, measurement and data communication.
