The invention discloses a high-plant-to-on-load transformer-based voltage regulation system and method. The voltage regulation system comprises an external DC power supply and an automatic voltage regulation device, wherein a power switch is arranged between the external DC power supply and the automatic voltage regulation device, power-on operation is automatically completed by the device after the power switch is switched on, the automatic voltage regulation device comprises a strong electricity input loop, a weak electricity input loop, an analog input loop, an outlet loop, an output signalloop and a CUP logic plate, and the strong electricity input loop, the weak electricity input loop, the analog input loop, the outlet loop and the output signal loop are connected with the CUP logicplate. By the voltage regulation system, the operation of an operator is reduced, the misoperation probability is reduced, the logic function is more complete, the automation is higher, and the maintenance of a power utilization voltage for a plant is wider.
Description
technical field [0001] The invention relates to the technical field of automatic voltage regulation of high power plant transformers, in particular to an automatic voltage regulation system and automatic voltage regulation method of high power plant transformers. Background technique [0002] Generally, the high power transformer or start-up transformer in a power plant is equipped with an on-load tap changer or not, but the power plant often does not pay attention to the impact of the power supply voltage on the unit auxiliary equipment. Or when it is too low, if the transformer tap is not adjusted in time, it will cause the auxiliary machine to operate under abnormal voltage, affect the normal operation and service life of the auxiliary machine, and cause harm to the plant's electrical equipment. However, with the rapid development of automation technology, power plants are gradually realizing automatic control, and the plant power voltage will gradually realize automatic ...
