空载变压器励磁电流无功补偿的技术研究
Research on excitation current of reactive power compensation technology for transformer under the no-load conditions
摘要
Abstract
In order to improve the power factor of the new large transformer in no-load operation conditions and realize its economic operation , we have analyzed loss of transformer that generated in no-load, fund out the reason of the re-ducing power factor of transformer and put forward a method which is based on the field current reactive power com -pensation to improve the power factor of transformer under the no-load conditions .Through introducing Matlab simula-tion modeling of transformer under the no-load running and analyzing the field data during commissioning , the power factor was obviously improved and reached the appraisal of the power factor requirements .The content which is re-ferred in this paper has been applied to the actual operation of the transformer , and achieves good results .关键词
