| Abstract: | Aiming at the situation of the calculation complex and liable to make mistake in maintransformer differential protection verification, using Nanrui RCS- 978 main transformer differentialprotection device as an example,analyzes the two type of main transformer differential protectionverification methods which are widely applied. puts forward automatic calculation module for maintransformer differential protection verification based on EXCEL. The application result shows thatautomatic calculation module can reduce the calculation complexity of main transformer differentialprotection verification, improve the correctness and efficiency of the verification. |
