Application of digital computers to power system protection

What is digital signal processing in power system protection and control?

After introductory chapters related to protection technology and functions, Digital Signal Processing in Power System Protection and Control presents the digital algorithms for signal filtering, followed by measurement algorithms of the most commonly-used protection criteria values and decision-making methods in protective relays.

What is a power system protection and control information platform?

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.

How does digital technology affect a protection system?

With the development of digital technology, more and more protection functions for any given apparatus (line, transformer, generator, etc.) have been implemented within one protective device to achieve a certain degree of integration.

What are the developments in power system protection & wide area control?

With the fast progress in high-speed communication network and information technology, there were significant developments in power system protection, power system control and wide area control in recent years, particularly in the wide-area and integrated protection.

When did power system protection start?

Power system protection emerged at the beginning of the last century, with the application of the first electro-mechanical overcurrent relay.

What is a remote terminal & microcomputer protection device?

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.
