description The invention discloses a reactive power and voltage emergency coordination control device and control method. The device includes a coordination control master station, regional master stations and sub-stations, and adopts a centralized control structure. Capacitors and reactors are switched on/off according to the voltage and DC fault situation of the regional master stations. The coordination control master station forwards the fault information of the regional master stations and receives reactive power and voltage sensitivity information of relevant stations sent from an AVC master station. Each regional master station collects the information of capacitors and reactors in the region, and makes a comprehensive decision based on the DC fault, reactive power and voltage sensitivity and other information. The sub-stations are information acquisition and execution stations, and can carry out switching-on/off actively according to the local voltage. The reactive power resources in the power grid can be quickl
