Centralized Management System for an Industrial Microgrid;Case Study: Razi Petrochemical

With the entry of microgrid systems into the industry, the traditional protection system has faced many challenges, connection and outag of the power grid from microgrid systems lead to the grid parameters changes. traditional protection systems Data are traditionally predicted and used before operation. Here, the adaptive protection plan isintroduced. while identifying the problems of using microgrids. Adaptive protection tends to predict the protection of electrical and microgrid networks for different work modes and by using a protection management center, protection system data transfer to the system with the network conditions. In this work, Razi Petrochemical Electricity Networkand its power plant have been introduced as an industrial microgrid, then simulations are performed in Digsilent software. The interaction of the microgrid and the main network negative effects on the traditional protection system have been investigated and identified. Finally, the Utilization of adaptive protection plan and protection layers is definedand dual protection relay settings are recommended for optimal operation of this plant.
