摘要
分析了带隔直电容不平衡电桥法检测方法和直流系统故障隔离原理,提出发电厂直流系统故障隔离方案,设计了直流保护系统整体框架。该发电厂直流保护系统进行了试运行,结果表明该系统可准确预测直流系统故障并对故障进行隔离。
The detection method using unbalanced bridge with blocking capacitor and the principle of fault isolation for DC system are analyzed,the scheme of fault isolation for DC system of power plant is put forward,and an overall framework of DC protection system is designed.The trial operation of DC protection system of power plant is carried out,and the result indicates that the system is able to accurately predict the faults in DC system and isolate the faults.
