The invention discloses a dynamic reactive power compensation device. A low-voltage busbar is connected with voltage detection and reactive current detection through wires, the low-voltage busbar is connected in series with a current transformer, the current transformer is connected with current detection and the reactive current detection through wires, the input ends of the voltage detection, the reactive current detection and the current detection are respectively connected with the input end of a CPU (central processing unit), the output end of the CPU is connected with the output end in a pulse mode, the output end in the pulse mode is connected with the input end of pulse distribution, and pulse signals are connected to a switching switch of a capacitor bank. The switching switch of the capacitor bank is composed of thyristors V1 and V2 which are reversely connected in parallel. The highest action response speed of the device disclosed by the invention is 60ms, so that the device fully meets the require
