Abstract

Stability of power system can be defined as its property which keeps several parameters in the balanced operating condition when sudden disturbances occur. In the stable operating condition, mechanical power input in the prime mover poses an equilibrium state with the electrical power output. Such condition makes all generators spin in synchronized speed.Disturbances in a power system tend to make out-of-balance situations, which in turn force the engineers to develop a better power system management. One of power system management that needs a high concern is load shedding strategies. It highly depends on system frequency, since the frequency is the most sensitive value affected by imbalance condition.Load shedding strategy uses frequency relays as the devices to break the connection of circuit breakers by measuring system frequency. The relays can be programmed to break specific circuit breakers if the system frequency reaches a defined value set by programmers. By inspecting this strategy, there is a high expectation to make a better power system, especially in 500 kV interconnected power system in Java-Madura-Bali.
