Embodiment Construction
[0021] In one embodiment, such as figure 1 As shown, a method for evaluating the maximum load rate range of a transformer includes the following steps:
[0022] Step S110: Obtain the number of transformers running in parallel, the overload capacity of the transformers, the maximum daily load rate of the transformers in summer typical load, and the daily minimum load rate of transformers in typical winter load.
[0023] Specifically, the overload capacity refers to the capacity range that the equipment can withstand after exceeding the rated limit. In the field of communication power supplies, equipment has nominal ratings to indicate the load it can carry, and there is often a margin during design, which is called overload capacity. The typical load day generally refers to the day with the largest load in summer, or the day with the smallest load in summer, and also the day with the largest load in winter, or the day with the smallest winter load. Specifically, typical load d...

The present invention relates to an evaluation method and a system for the maximum load range of a transformer. According to the technical scheme of the invention, the number of transformers in parallel operation, the overload capacity of transformers, the summer typical load minimum daily load rate of transformers and the winter typical load minimum daily load rate of transformers are obtained. The first range of the maximum load rate of transformers is calculated according to the number of transformers and the overload capacity of transformers. The operation safety of transformers is considered. According to the summer typical load minimum daily load rate of transformers and the winter typical load minimum daily load rate of transformers, the second range of the maximum load rate of transformers is calculated. Meanwhile, the load characteristics and the efficiency characteristics of transformers are comprehensively considered. According to the first range of the maximum load rate of transformers and the second range of the maximum load rate of transformers, the reasonable range of the maximum load rate of transformers is calculated and outputted. Therefore, the range of the maximum load rate of transformers is evaluated, while the operation safety, the load characteristics and the efficiency characteristics of transformers are comprehensively considered. The accuracy is improved.
Description
technical field [0001] The invention relates to the field of transformers, in particular to a method and system for evaluating the maximum load rate range of a transformer. Background technique [0002] In terms of research on power grid and equipment utilization efficiency in China, the researches on Northwest Power Grid and East China Power Grid are more representative. In terms of the Northwest Power Grid, the grid operation research report issued by the Northwest Electricity Regulatory Bureau mainly uses the maximum load rate of the line, the average load rate of the line, the maximum load rate of the main transformer, and the average load rate of the main transformer to characterize the utilization efficiency of equipment, and counts the Northwest region. The annual grid equipment utilization efficiency of the power grid for several years, but did not propose a reasonable range of equipment load rate. In terms of the East China Power Grid, the East China Electricity Reg...
