A BLOCKING SCHEME FOR CURRENT CIRCUIT BREAKING IN DIFFERENTIAL PROTECTION SYSTEM OF TRANSFORMERS |
| |
| Abstract: | A blocking scheme for current circuit break in differential protection system of transformers performed by software of micro-computer is proposed in this paper. Next, a completed soft-ware block diagram is described. At last, the tests of the proposed scheme on both the digital simulation and the physical transformer model are performed. The results indicate that the scheme is feasible, simple and reliable. |
