摘要
Abstract
ABB UNITROL 5000 excitation system is widely used in large-scale power plants in China which uses ARCNET as its inner communication mode. In allusion to twice accidents of tripping caused by communication failure of the UNITROL 5000 excitation system of the No.2 power unit in one power plant,this paper analyzes fault alarming information,compares twice accidents,studies ARCNET communication principle and finally locates the failure based on field simulating test. It al-so proposes precaution measures from different angles so as to prevent similar accidents happening again.关键词
