Abstract: Power system safety is a one of the major focused areas in recent days due to mismatch between power generation and power demand. Successful operation of a power system depends largely on the engineer's ability to provide reliable and uninterrupted service to the loads. Safety includes both the operation and planning of power system networks i.e both voltage and frequency at allloads must be held within acceptable tolerances so that the patron equipment will operate efficiently.Inordertoachieve safety the system generators should run synchronously andwith adequate capacity to meet the load power demand. Secondly, the integrity of the power network should 'be maintained to ensure continuity of service. Power systems occasionally suffer perturbations. These perturbations may be small originating from random changes in loads or they may be severe arising out of a fault on the network.This paper presents brief overview of differenttypesofinstabilities inpower systemandthe techniques used to overcome it. The paper also compares the applicabilityof different techniques on the basis of performance.
