Study On Economic Operation Technology Of Transformer Based On Double Source Power Supply

With the development of power grids and the increasingly high demand for security of power supply,we want power grids to maintain economic operation when the security being improved.The economic operation of transformer based on double source power supply,meet of user’s power supply as well as quality,is to maximize the reduction of energy loss of transformers in supply lines by means of technical measures.It is an effective way to reduce power loss by adjusting the operation of transformers in the substation,which is one of main measures taken in the current Transformer economic operation.However,power lines and different combinations of transformers have a significant impact on substation economic operation,thus it is necessary to take both transformers and power lines in substation into consideration and probe a safer and more economic operation mode.Taking Chengzhong Zibo transformer substation as an example,this article gives a technical research on economic operation technology of transformer based on double source power supply.When transformer load changes,the optimal combination of transformers and power lines in transformer substation is found through theoretical analysis of the data collected.Meanwhile,the article proposes such kind of combination of operation mode as“double source power supply to run as main,one prepared for one to run as a supplement”combination.This paper provides the theoretical analysis for the operability and actual data verification for the economic application of mentioned operation mode.Meanwhile,it gives an analysis of auxiliary transformer cooling equipments’ economic operation,and takes switching over the auxiliary transformer cooling equipments into transformer economic operation range.By adjusting the way of operation,energy loss can be minimized,also safe and economic operation of substation can be realized.
