The Technical Research and Application of Rapid Adjustment of Three-phase Load Imbalance in Distribution Network

Based on the data of the metering automation system and the marketing system, and problem-oriented, two three-phase load unbalance adjustment schemes of the distribution transformer are proposed. Two typical stations are selected for comparative verification. The results show that the mean value adjustment method is more suitable for light load distribution transformer and the extreme value adjustment method is more suitable for heavy load distribution transformer. Use WPS table to program the calculation process. That is, the system data can be imported to simulate the generation of the adjusted load operation state diagram and the anti-overload state diagram, and automatically calculate the optimal adjustment value and adjustment interval for each phase. Improve efficiency and promote use.
