Abstract
One of methods that can be used to determine the stability of a power system if the fault occured is the equal area criterion method. The equal area criterion method (Equal Area Criterion, EAC) is an example of a direct method for predicting the stability and also the critical clearing time (Critical clearing time). However, to calculate the complex calculations required to determine the equivalent impedance of each condition system. In this study used several approaches to facilitate the calculation of the equivalent impedance. This method uses the equation of power losses. This method is equivalent impedance using modified with Ploss and Qloss for Determining Pmax. From the analysis, it can be concluded the use of this method is quite accurate in analyzing or calculating the transient stability of the generator system in South Sulawesi, with each loading condition, before, during and after short circuit. Generator being looked at is Bakaru, Pare, Suppa, Barru and Sengkang.
Highlights
In the electric power system operation, the system conditions change suddenly, usually occurs due to a disturbance such as a short circuit in the power system, but it caused the release or the addition of load suddenly [1]
We need a power system analysis to determine whether the system is stable or not, if there is fault on the system
The stability of a power system is the ability of power system consists of several Transient ability of a power system to maintain synchronization after a large disturbance that is suddenly for about one "swing" with the assumption that the automatic voltage regulator (AVR) and the governor has not worked
Summary
In the electric power system operation, the system conditions change suddenly, usually occurs due to a disturbance such as a short circuit in the power system, but it caused the release or the addition of load suddenly [1]. Due to changes in operating conditions of the system, the system state will change from the old condition to a new condition. Short period between the condition is called a trantition period or called transient. We need a power system analysis to determine whether the system is stable or not, if there is fault on the system. Many methods are used to analyze the stability of the power
