The Effect of Operational Load Configuration to Transient Stability on Petrochina International Jabung

摘要

One of the parameters of the electrical power operating system stability is the need to balance the supply provided by the plant generation and its load requirement. The underway operation in PetroChina international jabung from time to time makes the need for operational loads tend to change. Replacement or additional load in the future also harmonized with the operational load configuration and the need for additional generation supply. A transient analysis is needed to determine the limits of system stability in dealing with various kinds of interference including the ability of the system to overcome generator tripping disturbances, short circuit, and motor starting disturbances. The analysis is used to provide the best recommendation for whether the system needs additional supply or the best scheme for load shedding. Analysis of the interference is seen from the frequency response, rotor angle response and voltage response in the system.
