Abstract


In recent years, frequent international large-scale power outage, causing enormous economic losses, the paper’s reearch results at home and abroad, a chain reaction accident on the grid of critical phenomena in the initial analysis carried out by self-organized criticality of understanding Power chain reaction accident in critical phenomena, through the blackout and the nature of the concept of understanding, analysis of the reasons for the blackout, the establishment of a simplified power system model of the transmission will be three kinds of typical power system block algorithm compared with MATLAB language program for three kinds of examples of sub-block approach to the programming, given the final outcome, the results were compared.In this system the power of a node changes start on the grid of self-organized criticality of the preliminary analysis, to study in recent years, the frequent blackouts in the accident. Grid node in the critical phenomena, power distribution, the critical point of the determination of measures to be taken to avoid the critical operation of power grids in order to prevent blackouts in chain reaction accident is the purpose of this article.
