Abstract
The future growth of the power system will be more dependent on the ability of improving the delivery system that already exists, rather than to build new transmission lines and power stations, for reasons of economy and environment. Line loadability is defined as the degree of line loading permissible given the thermal, voltage drop and stability limit. Nevertheless, power transfer capability is influenced by voltage level and line length. This project is focusing on the analysis on power transfer, loadability limit and stability of transmission lines in a power system. Power transfer capability of the system shows how much interarea power transfer can be increased without compromising system security. Accurate identification of these capabilities provides important information for the planning and operation of both the bulk power market. Stability as defined above encompasses all types of stability likely to be encountered in power systems. A power system at a given operating state is stable if following a given disturbance, or a set of disturbances, the system state stays within specified bounds and the system reaches a new stable equilibrium state within a specified period of time. PSSE software is used for generating data through simulation on IEEE 39 Bus Test System. This system used to analyze power transfer and loadability limit of transmission lines in power system. By using Power-Voltage analysis (PV analysis), the power transfer and loadability limit of transmission lines and the stability of the system were analyzed.
