Abstract

The invention relates to a voltage regulation system and method of a power distribution transformer based on response to demand, and belongs to the technical field of intelligent power distribution. A voltage set reference value of the voltage-regulating power distribution transformer is adjusted according to load periods of power utilization; in the peak period of power utilization, the voltage set reference value is reduced, namely the power supply voltage at the low voltage side is reduced in the peak period to reduce the power load; and in the valley period of power utilization, the voltage set reference value is increased, namely, the power supply voltage at the low voltage side is improved in the peak period to increase the power load. According to the system and method, demand is responded actively, the power load can be actively reduced in the peak period, and increased in the valley period, and thus, active response to demand in public mechanism, commercial building, industrial enterprise and residential districts is realized.

Description

technical field [0001] The invention relates to a distribution transformer intelligent voltage regulation system and method based on demand response, belonging to the technical field of intelligent power distribution. Background technique [0002] In order to maintain the stability of the power supply voltage, the high-voltage side of the distribution transformer is generally equipped with a main transformer tap. By adjusting the position of the high-voltage side tap of the main transformer, the stability of the power supply voltage can be achieved in the case of grid voltage fluctuations. For 10KV power distribution The transformer is generally equipped with 5 taps for voltage regulation, and the voltage between each tap is ±2.5% of the rated voltage. For oil-immersed distribution transformers, it is realized by using end taps, and for dry-type distribution transformers. It is realized by way of center tap. [0003] Most of the tap adjustments of current distribution trans...
