Introduction In order to improve the reliability of relay protection from the point of view of data center as a whole, the relay protection system of power dispatch control center is designed entirely, and an integrated relay protection idea is proposed. Method Starting from the entire distribution structure of power dispatching control center, the integrated design of relay protection was coordinated, and the whole distribution facilities were controlled by an integrated mechanism.
Result According to the research in this paper, it is proved that the integrated relay protection can greatly simplify the relay protection strategy of the original power dispatch control center, improve the protection action time, ensure the selectivity of relay protection action, and improve the reliability of power supply.
Conclusion This paper provides an idea of integrated relay protection , which provides a forward-looking idea and direction for the development of related products.
