The invention discloses a method for coordination control of controllable shunt reactors. The method comprises the steps that a controllable shunt reactor control system submits the controllable shunt reactor lifting capacity to a master safety control station device through a home-station safety control substation device; when the master safety control station detects that line tripping occurs on a power transmission channel and the channel tide is larger than a certain value before the accident, the master safety control station sends information to the controllable shunt reactor control system through each safety control substation and locks the original control logic; the safety control substations collect the busbar voltage of each station after the accident and submit the voltages to the master safety control station, the master safety control station makes a decision in a centralized mode, and a command is given to put into part of capacity into the controllable shunt reactors according to the timing sequence if overvoltage is detected; the controllable shunt reactor control system receives and executes the command of adjusting the capacity; the original control logic of the controllable shunt reactor control system is open after a period of time. By the adoption of the method, coordination control of multiple sets of dynamic reactive power compensation equipment distributed in multiple transformer substations can be realized, overvoltage can be effectively restrained after the accident, and system voltage collapse caused by simultaneous incoordinate actions of multiple sets of controllable shunt reactors can be avoided.
