New-type urbanization-based low voltage treatment measures optimization method

Abstract

The invention relates to a new-type urbanization-based low voltage treatment measures optimization method, which comprises the steps as follows: system parameters of a power distribution network are obtained; the maximum load as shown in the specification of a distribution transformer is calculated according to the distribution transformer capacity; eta represents the load rate of the distribution transformer; S represents the capacity of the distribution transformer; rhi represents a power factor; the current power load of a load terminal is counted; the reason of a low voltage is judged according to the system parameters, and the power load, namely the maximum load of the distribution transformer; if the current power load is greater than the maximum load P of the distribution transformer, voltage adjustment is carried out through a power distribution device; and if the current power load is smaller than the maximum load P of the distribution transformer and when terminal voltage fluctuation of a to-be-tested circuit is greater than a standard value, voltage adjustment is carried out through a wire with a relatively large wire diameter. The terminal voltage of an urban power grid is improved; the reactive current flow of the circuit is reduced; the electric energy loss is reduced; and the quality of a power supply voltage of a rural power grid is improved.

Description

technical field [0001] The invention relates to a low-voltage control method, in particular to a method for optimizing low-voltage control measures based on new urbanization. Background technique [0002] In recent years, with the development of the economy, the load of urban power grids has increased dramatically, and the demand for electricity from users has continued to increase. However, the lines of my country's rural power grids are too long, the wire diameters are too thin, and the booster and compensation equipment are insufficient, resulting in the terminal voltage and power of rural power grids If the factor is too low, it will seriously affect the normal power consumption of rural grid users, so a series of voltage regulation measures must be taken to ensure that the voltage meets the requirements of the grid. If the grid user's voltage is too low and the power factor is too low, the equipment will fail to start and the equipment will not operate normally, which wi...

If the grid user's voltage is too low and the power factor is too low, the equipment will fail to start and the equipment will not operate normally, which will affect the normal power consumption of the user

At present, the low-voltage control of rural power grids is to install a single reactive power compensation device on one line. There is no communication between the devices, and they cannot be controlled uniformly. The cost is high and the voltage control effect is not obvious.
