Vector jump relay on SIMULINK: implementation of anti-islanding techniques in distributed generation systems

The growing demand for electricity has encouraged consumers to invest in generators connected to consumer facilities. This type of generation is known as distributed generation (DG). DG has advantages, but it can bring some inconveniences, such as the risk of feeding a section of the network during maintenance (islanded operation). To prevent this from happening, as the DGs must have protections that must identify the loss of connection to the network. Among the main methods of island detection are vector jump relays. Studies aimed at islanding detection can be performed using different softwares, among them, one can mention, MATLAB/SIMULINK. However, there is no document in the literature that clearly describes how to implement a simulation of island detection using the vector jump method on MATLAB/SIMULINK. This work contributes to provide a detailed orientation of this implementation using a synchronous machine serving as a guide for students who start studies in distributed generation.

Automated summary

The increasing demand for electricity has led to investment in generators connected to consumer facilities, known as distributed generation (DG). While DG has advantages, it can pose risks like islanded operation. To prevent this, proper protection and island detection methods like vector jump relays are essential. Studies using software like MATLAB/SIMULINK can help in this area, but there is a lack of documentation on implementing island detection using the vector jump method in these programs. This research serves to provide detailed guidance on implementing island detection using synchronous machines for students starting in distributed generation studies.
