The Reseorehing About Measure Componemt of Roter Lou-Yoltag in Generatet Field-loss Proteceion

在分析发电机失磁保护构成、特点的基础上,对其转子低电压元件的原理与实现进行了研究,提出了可行的改进方案。研究表明,新方案可提高失磁保护的可靠性。

Based on the analysis for component characteristic of generator field-loss protection, it and re searchs the principle and realizablity of rotor lowvoltage component and advances a feasible improvement plan. It is proved by analysis that the new plan can improve the reliability of field-loss protection.
