Why are smart substations important?

Smart substations are important part of the modern smart electric grid, as they provide seamless integration of renewable energy resources, enhance grid reliability, improves efficiency of the grid, and provide better power quality. A smart substation consists of numerous advanced digital components.

What are the key points of smart substation research?

The key points of the smart substation research include self-diagnosis of substation equipment, intelligent primary equipment, and station and wide-area protection and control system, so as to greatly reduce the floor space and significantly improve the safety, reliability, and economy of the power grid.

What are the components of a smart substation?

Some of the main components of a smart substation are described here − Intelligent Electronic Devices (IEDs) − These devices are used for real-time monitoring and control of the power system. The examples of IEDs include smart sensors, digital relays, automated switching devices, etc.

What is a smart substation platform?

The platform solves the problems of too many station control systems and interfaces, poor data sharing and applying synthetically, and meets the requirements of intelligent substations in digitization of information, integration of functions, compactness of structures, and visualization of status. Fig. 1.5.

What is a smart substation communication system?

This communication system also connects IoT devices used in the smart substation. Automated Control and Monitoring System − This system is employed for providing a centralized control, monitoring, and data analysis mechanism in the smart substation.

How to design a smart substation?

The smart substation should be designed from the top level and set up on a unified information platform to realize the comprehensive data collection, centralized online monitoring, and state diagnose of the main and auxiliary equipment in the substation.
