Analysis of Parallel Economic Operation and Switching Strategies of Mobile Capacity Enlargement Distribution Transformers
Published 2023-02-01“… In view of the problem that the seasonal electric load fluctuations in tourist areas and rural areas have a great impact on the safety and economy of distribution transformer operation, the parallel operation of the capacity-added transformers and the throwing-off strategy scheme are proposed.In order to improve the utilization rate of the capacity-increasing transformer as well as the operation efficiency of the parallel transformer set, the impedance range of the mobile capacity-increasing transformer is optimized and calculated by combining the existing transformer condition in Lijiang area.Subsequently, considering the operating interval length, power saving and other influencing factors, based on fuzzy decision theory, a fuzzy strategy model is established and combined with period control, so as to optimize the switching strategy.The results show that the reasonable selection of the impedance interval of the capacity-adding transformer can increase the operating efficiency of the transformer bank.The transformer switching strategy improves the power saving effect of the parallel system, circumvents the fluctuation error of daily load curve, and can improve the economy and reliability of power supply.…”
