摘要
分析了核电厂备用柴油发电机(SDG)保护存在的问题,从保护装置的性能、备件、定值及维护的角度阐述了改造的必要性。通过对改造前后保护装置的对比,介绍了新保护装置的优点,并对保护定值进行重新整定,解决SDG保护装置面临的问题,完善了保护定值配置,对SDG运行维护与整定计算有一定的实用参考价值。
The existing problems in the protection of power plant standby diesel generators(SDG)are analyzed.From the perspective of the performance,spare parts,fixed value and maintenance of the protection device,the necessity of the transformation is explained.By comparing the protection devices before and after the transformation,the advantages of the new protection devices are introduced.The protection setting value is reset to solve the problems faced by SDG protection device and improve the protection setting value configuration,which has a certain practical reference value for SDG operation maintenance and setting calculation.
