Abstract

This application provides a distribution feeder self-adaptive voltage regulation setting algorithm, including: collecting bus load parameters and each feeder load parameter at different time sections; by comparing the bus load parameters and each feeder load parameter at each time section, determine The maximum and minimum operating modes of the total bus load determine the maximum and minimum operating modes of each feeder load; calculate the overall load change voltage adjustment range according to the bus load parameters corresponding to the maximum and minimum operating modes of the total bus load; Adjust the voltage adjustment range of each feeder end voltage; adjust the feeder end voltage corresponding to the maximum and minimum operation modes of each feeder load to the bus voltage, and obtain the voltage demand range of each feeder for the bus voltage; integrate the overall load change voltage adjustment range and voltage demand range to get the adjustment range of the adaptive voltage regulation. The application has the obvious advantages of simplicity, reliability and low cost.

Description

technical field [0001] The present application relates to the field of power distribution technology, in particular to a distribution feeder adaptive voltage regulation and setting algorithm. Background technique [0002] Voltage is one of the basic indicators to measure power quality, and it is a sign reflecting the balance and reasonable distribution of reactive power in the power system. Unqualified voltage will cause serious harm to the power grid. Excessive voltage deviation will affect the quality and output of industrial and agricultural production, damage power equipment, and even cause systemic "voltage collapse", resulting in large-scale power outages. Regulating the voltage of the power system so that its variation does not exceed the specified allowable range is an important means to ensure the stability of the power system and the safe and economical operation of various power equipment and electrical appliances. [0003] In the prior art, the commonly used vol...
