The present invention relates to a method for detecting and analyzing an abnormal communication link of an intelligent substation based on total-station information. The method comprises the following steps: establishing a network structure association matrix for communication between devices; establishing a receiving-transmitting configuration association matrix of a device communication source and a device target; acquiring communication link alarm information from all devices in real time; comparing a device receiving-transmitting association relationship with a configuration association relationship; and determining the range of the devices which cause abnormal communication. The method for detecting and analyzing the abnormal communication link of the intelligent substation based on the total-station information presented by the present invention has a positive significance for finding a fault in time accurately and ensuring the safe operation of the intelligent substation.
