Suppression method for voltage fluctuation and flickering of power grid

Abstract

The invention provides a suppression method for voltage fluctuation and flickering of a power grid, and the method has the advantages of reasonable and practical design, convenience in operation and high application effect. According to the technical scheme, a transformer tap is selected to ensure voltage level of an electric device, an on-load voltage regulation transformer is adopted with regard to a newly-built transformer and power distribution transformers additionally arranged at users, a capacitor is set for artificial compensation and comprises parallel compensation and series compensation, a current limitation reactor is additionally arranged at a circuit outlet, the power distribution transformers run in parallel, a high- and low-voltage distribution line scheme with minimum reactance is adopted, a large-scale induction motor with the capacitor is used for compensation, and a power stabilizer is used for voltage stabilization. The suppression method has the advantages of reasonable and practical design, convenience in operation and time saving, the phenomena of frequent supply voltage fluctuation and flickering of the power grid are eliminated, and the power supply quality is improved.

Description

technical field [0001] The patent of the present invention relates to the technical field of power supply, in particular to a method for suppressing grid voltage fluctuation and flicker. Background technique [0002] At present, the power supply voltage of the power grid often fluctuates and flickers. This phenomenon is mainly caused by incorrect methods and methods of power supply, no addition of on-load voltage regulating transformers, no capacitors, and no current-limiting reactors installed at the line outlet. Wait. Contents of the invention [0003] The purpose of the patent of the present invention is to provide a method for suppressing power grid voltage fluctuations and flickers with reasonable and practical design, easy operation and good use effect. The technical solution is: select transformer taps to ensure the voltage level of electrical equipment, Or the user adds a new distribution transformer, adopts an on-load tap changer transformer, and sets a capac...
