Title
Design of a Sliding Mode Disturbance Observer for Out-of-Step Protection
Abstract
If a failure occurs in the power system, the electrical output of the generator changes, which can be regarded as a result of an external disturbance input. This paper deals with the out-of-step protection problem by using a disturbance observer to maintain synchronization of the power system. A disturbance observer is designed to estimate the disturbance that affects the stability of the system owing to an abrupt load input or output as well as various faults. The performance of the designed observer is verified by simulation of the single-machine infinite bus power system. Simulation results show that the disturbance can be estimated successfully within the critical fault removal time and the system can be synchronized against the fault.
