Development of an integrated power system analysis package

With the present de-regulation in the electric power market, powerful analytical tools are required for the planning and evaluation of feasibility of wheeling of electrical power. A major role for power system engineers is confirming the stable operation of power systems in order to maintain dynamic stability voltage stability, etc. under a wide variety of constraints. Conventional computer software used in power system analysis is, however, not convenient or friendly because it requires that data be input in text form, including even the data for modeling generators, their controllers, loads and so on. In this paper, the authors present a new integrated power system package named Impact (Integrated and Multi-purpose Package of Advanced Computational Tools for power system engineering). This package was developed to provide a fully graphical user interface (GUI). Impact is a package of several useful integrated analytical applications. Users can easily handle bus configurations from the powerful GUI. The power of the GUI coupled with full integration of the application is demonstrated in many attractive themes
