This method has been gaining traction in the distribution electrical system, allowing greater autonomy in fault detection and resolution. But what exactly is self-healing, and how can it assist the electrical sector?
What is self-healing?
Self-healing, a real-time monitoring technique, has the ability to identify and correct faults in the electrical grid autonomously. When a power outage occurs, this technique can identify the type of fault and take necessary measures to restore the system.
This capability is achieved through a smart grid equipped with sensors and monitoring devices that detect fault points.
Additionally, it allows for a faster solution to system defects, reducing downtime. This is because the system operates independently, able to restore power in affected areas without the need to dispatch technical teams to the site.
The utility and implementation of Self-Healing technique
To implement the self-healing system, you need to install equipment with remote control and use teleprotection. Coordination among all elements plays a crucial role in ensuring adequate protection during maneuvering and recovery processes, avoiding unwanted failures.
In this case, we recommend using IEDs (Intelligent Electronic Devices) to control reclosers and switches. These devices are commonly integrated into utility supervisory systems, increasing the reliability of the electrical system.
It is important to note that this technique is already widely used in other countries, such as the United States and Japan, and is in the implementation phase in Brazil. In this context, HVEX is developing technologies to implement self-healing concepts in the Brazilian electrical system.
