Abstract
The development of smart grids with increasing penetration of renewable energy sources into the electrical grids have raised several technical challenges for the control and monitoring. One of these challenges is the system reliability, which depends on power grids’ resilience and high integrity of data. The protective relays play vital role in the grid reliability that involves monitoring power lines and mitigating blackouts. In a large power grid, the protective relays operate locally by controlling the opening and closing of switches (breakers) in power lines, which allows to disconnect or remove from service any part of the power system when it operates in abnormal manner that might cause damage to the rest of the system. However, these relays are prone to failures, which lead random opening/closing of the breakers. Therefore, to back up the protection systems, it is necessary to study the relays failures and it effect on a large power grid. The focus of this research is the development of Hardware-in-the-Loop (HIL) Simulation that allows to safely emulate and study the power systems and relays under different operating condition. HIL is the standard industrial method for developing and testing the most complex control, protection and monitoring systems. In this HIL simulation, we use a real-time simulator as a virtual representation of a large power system connected to a real device that is a Schweitzer relay (SEL). A host computer is used to develop a simulation model of a power system and then runs in a target that is real-time target simulator that is an opal RT system. The HIL simulation contains software/hardware interface that enable to control the virtual input to the real system (SEL) and vice-versa.
