摘要
分析使用几种原理的变压器保护 ,将各有优缺点的不同原理综合应用在同一保护上 ,提出多原理的数字式变压器保护 ,采用硬件和软件双重冗余性原理 。
The article analyzes application of transformer protection based on different theories, and brings forward much theory's digital transformer protection, theories with different advantages and disadvantages are used together in the same protection,the protection adopts hardware and software's redundancy, which improves reliability and sensitivity of the protection.
