Transformer type voltage control device, reactive power adjustment type voltage control device, and distribution system voltage control system

摘要

The transformer type voltage control device uses the reactive power generation data (reactive power integral value, positive maximum reactive power integral value, and negative maximum reactive power integral value) received from the reactive power control type voltage control device. Calculate the total power integration value, total positive maximum reactive power integration value, and total negative maximum reactive power integration value, and calculate the positive reactive power margin based on the total positive maximum reactive power integration value and the total reactive power integration value. , The negative reactive power margin is calculated based on the total negative maximum reactive power integral value and the total reactive power integral value, and the positive reactive power margin is positive when the positive reactive power margin is smaller than the positive threshold. If the tap position of the transformer type voltage control device is changed so that the negative reactive power margin is smaller than the negative threshold, the negative reactive power margin is larger than the negative threshold. Change the tap position so that To.
