Studying and building programme for simplifying electrical network diagram using Gaussian elimination algorithm

Tóm tắt

Along with the development of the socio-economy in general and of science and technology in particular, the need for energy is increasing.Particularly, electrical energy plays a very important role. Load of power systems continuously develops and expands, leading to several difficulties in management and operation of power systems. In order to ensure security of power systems, during their operation, parameters of system mode in different operating conditions need to be calculated and assessed with respect to their limits. Thence, security of power systems can be evaluated and measures for enhancing system security can be provided. A methodology for calculating power system that satisfies both computation time and accuracy is extremely necessary. Gaussian elimination algorithm is very helpful in supporting such methods. This paper analyzes mathematical fundamentals and the application of Gaussian elimination algorithm to build programme for simplifying electrical network diagram that is useful to deal with several issues in power systems such as short-circuit calculation,stability analysis etc.
