Economic Operation Of Transformer For Cities With Automatic Technology In Low-Voltage Distribution

Based on the economic operation of transformer for distribution and the application of it, the operation method is discussed in detail in this paper. The paper analyzed several conditions of economic operation of transformer for distribution and described how to combine the principle of economic operation with the practice for the purpose of reducing the electrical energy loss and raising the power factor of source side. The paper also discussed the normal regulation methods of economic operation and gave a new method of super-short-term load calculation which resolved the choice of the shut-time point of the distribution transformer, using a liner-trending 2-step self adaptation coefficient calculation.The automatic technology of low-voltage distribution is used in the economic operation of transformers, whose function and principle are described in detail.Combined with the practice,beneficial analysis is carried on to show that the technology acts positively on saving electric energy and investment.
