The invention discloses an energy storage power station remote control time delay test method and device, and the method comprises the steps: carrying out the time synchronization of all devices in anin-station communication network, and enabling all the devices to be in a unified time standard; performing communication monitoring on each communication stage according to pre-divided communicationstages to obtain corresponding communication message data; performing unified protocol conversion on the acquired communication message data of each communication stage; reporting a message receivingtime stamp to the communication message after the protocol conversion; and calculating the communication delay of each communication stage and the remote control delay of each remote control operation according to the communication message timestamp of each communication stage, and further calculating to obtain the comprehensive remote control delay data of the energy storage power station. Timedelay testing can be carried out on all remote control points in the energy storage power station, the testing efficiency is high, the cost is low, the testing result is reliable, and high-performancereal-time remote control communication of the energy storage power station control system can be achieved.
