The invention discloses a power distribution automation system wireless communication channel automatic test system based on a Metlab, is applied to on-site acceptance check of power distribution automation system terminal equipment and is for realization of quantitative testing of wireless communication channels and flexible setting of parameters such as IP addresses of master stations, times of sending data packets, sizes of the data packets, times of cycling of tests and test time intervals. The invention also discloses a power distribution automation system wireless communication channel test result automatic extracting method base on the Matlab. In the method, according to collecting of Ping command return results, a function of test result automatic collecting is realized by means of recognizing of key characters and obtaining of test data of various test contents. The invention also disclosed a power distribution automation system wireless communication channel test report automatic generation method based on the Metlab. According to the method, a test report is resolved into a plurality of sub-portions, and format parameters of the portions are obtained. The related parameters are guided into a self-brought formatting output function of the Metlab, and then subjected to combination to realize a formatting output function of the test report.
