The invention discloses a channel configuration method for rapidly locating the fault of a telecontrol management machine. The method comprises the following steps: firstly, performing topology combing on a channel connection condition; configuring parameters such as a channel table, a communication plant and station table, telemetry, tele-signaling, remote control and tele-adjustment; checking whether the channel status is correct or not, if so, configuring a routing table on a front server, otherwise performing reconfiguration after checking the parameter configuration; configuring a vertical encryption authentication device; performing a ping operation on each channel to check whether a channel service address can be ping-connected or not, if so, performing a next operation, otherwise checking the channel service address and performing correction; and testing the operation of the system. The channel configuration method has the beneficial effects of shortening the time for fault detection of the remote management machine, guaranteeing the normal operation of a control system, and greatly reducing the probability of occurrence of communication accidents in a power grid.
