Zusammenfassung:	The utility model relates to the technical field of reactive power voltage regulation, in particular to a dynamic reactive power compensation device for a long-distance transmission line of a power grid. The input end of a line voltage regulator is connected with the output end of a line inlet current transformer, and the output end of the line voltage regulator is connected with the input end of a line outlet isolating switch; and the input end of a compensation voltage regulator is connected with the output end of a line outlet current transformer, and the output end of the compensation voltage regulator is connected with the input end of a dry hollow series reactor. Through the reactive power compensation device, comprehensive control of voltage reactive power can be realized, and the voltage regulator is separately controlled to regulate the voltage in the absence of a compensation capacitor or the regulator of the reactive power compensation device is separately regulated when the voltage regulator does
