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 power system control?

with different dynamic and characteristics. The term power system control is used to define the of control theory and technology, optimization methodologies and expert and ligent systems to improve the performance and functions of p wer systems normal and abnormal operations. Power system controls keep the power system a secure state an

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.

What are Gency Control/protection schemes?

gency control/protection schemes [40–42].Furthermore, there are many controls and protections systems on transmission and distribution sides, such as switching capacitor/reactors, tap-changing/phase shifting transformers, HVDC controls, syn

Why do power systems need a PAC controller?

Nowadays, power systems’ Protection, Automation, and Control (PAC) functionalities are often deployed in different constrained devices (Intelligent Electronic Devices) following a coupled hardware/software design. However, with the increase in distributed energy resources, more customized controllers will be required.
