Abstract

The invention discloses a voltage regulator, a voltage regulating system and a voltage regulating method. The voltage regulator comprises a transformer, a plurality of load switches and a preset load switch, wherein the transformer comprises a primary coil and a secondary coil, the primary coil comprises a first end, a second end and a plurality of groups of serially connected coils, and the plurality of groups of serially connected coils are connected between the first end and the second end; the load switches correspond to the groups of serially connected coils one by one, and one end of each load switch is connected with one group of coils while the other end of the same is connected with the first end of the primary coil. One end of the preset load switch is connected with the first end of the primary coil, and the other end of the preset load switch is connected with any point in the groups of serially connected coils. The voltage regulator, the voltage regulating system and the voltage regulating method have the advantage that the problem in the prior art that power cannot be supplied normally since power is cut off for voltage regulation is solved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a voltage regulator, a voltage regulation system and a voltage regulation method. Background technique [0002] Voltage is one of the main quality indicators of electric energy. Voltage quality has a direct impact on grid stability, safe operation of power equipment, line loss, industrial and agricultural safety, product quality, unit power consumption and people's daily electricity consumption. [0003] With the development of social economy and the improvement of people's demand for electricity, the quality requirements of distribution network voltage are getting higher and higher. Due to a certain voltage loss in the operation of the distribution network, the voltage deviation at the user end exceeds the standard, especially in some remote areas, there is also the problem that the power supply radius exceeds the long-distance line specified by the state. For the terminal voltage o...
