Abstract
As the main energy consumption component of the substation, the power loss of the main transformers accounts for about 30% of the loss of the power system. And the loss monitoring and loss reduction analysis of main transformer is of great significance to the loss monitoring of substation. Generally, there are some shortcomings in the way of calculating the critical value of separate operation when using the uniform load distribution or direct parameter equivalence. Based on the improved critical partition method, the reduction analysis of two three-winding transformers is optimized, and the optimal reduction strategy of three-winding transformer is proposed. Based on the three-dimensional analysis of splitting operation loss, which further improves the accuracy and effect of loss reduction, a software system for online monitoring and analysis of loss reduction is designed and tested. The loss of transformers in operation can be monitored online and the loss level as well as loss reduction can be analyzed with high precision, which has a positive effect on the actual optimized operation and future load adjustment reference.
