Embodiment Construction
[0005] Series voltage compensation is a load-oriented compensation method. Its purpose is to inject a three-phase voltage with controllable amplitude, phase angle and frequency into the system during the power supply voltage drop and connect it in series with the power supply voltage to offset the drop component of the power supply voltage. , There are three ways of series voltage compensation: same voltage compensation, constant voltage voltage compensation and leading voltage compensation.

The invention provides a compensation method for series voltage of a power network. The compensation method is reasonable and practical in design and good in using effect. According to the technical scheme, series voltage compensation is a load-oriented compensation mode, and aims at injecting three-phase voltage of which the amplitude, the phase angle and the frequency are controllable into a system during a power supply voltage drop period to be connected with power supply voltage in series, so as to counteract drop components of the power supply voltage; and the series voltage compensation comprises the following three modes: same voltage compensation, constant-voltage compensation and leading voltage compensation. The compensation method has the beneficial effects that the compensation method is reasonable and practical in design, time-saving, labor-saving, and wide in market application prospect; and the stability and the power supply quality of network voltage are ensured.
Description
technical field [0001] The invention relates to the technical field of power supply, in particular to a method for compensating the series voltage of a grid. Background technique [0002] Today's grid power supply voltage drops seriously, leading to unstable power supply voltage and quality degradation and unnecessary consumption of electric energy, and dynamic compensation technology is a key way to solve this problem. Contents of the invention [0003] The invention provides a compensation method for grid series voltage with reasonable and practical design and good use effect. Its technical solution is: series voltage compensation is a load-oriented compensation method, and its purpose is to inject three-phase voltage with controllable amplitude, phase angle and frequency into the system in series with the supply voltage during the supply voltage drop, so as to offset There are three methods of series voltage compensation for the drop component of the supply voltage: sa...
