| 摘 要： | 从ZnO电阻的非线性特性出发，对采用ZnO作为灭磁电阻时阀片的均流/均能进行理论论述，指出阀片均能性能的好坏主要依赖于阀片自身的特性;分析比较了ZnO阀片的不同选择方法对均流/均能的影响，指出阀片的均流/均能很大程度上取决于可供选择的阀片的库存量。该研究为发电机励磁系统的安全稳定运行提供了有力的保证。

| Abstract: | Based on the research on a communication model for bus protection, the modeling of the relay control-word, relay lock logic and events is described in detail. Some ambiguous concepts defined in IEC 61850 standards are further analyzed. The point of view of using FCD m represent relay events in a report is emphasized. A method for improving the efficiency of reading and writing setting data is proposed and the confirming mechanism of data communication for events is given a detailed account. |
