Abstract: According to the function and application of smart substation integrated supervisory and control system, a substation level test system architecture is designed, each function module and information interaction process of test system architecture are analyzed. Then the substation level test technologies are deeply studied, including the station level data interaction testing technology, supervision and control system testing technology and remote functional testing technology. The station level data interactive test method is innovatively put forward, with which the test strategy can be configured, messages can be customized, and interactive behavior can be controlled. A closed-loop test method for supervision and control system information and electric power telecontrol device testing method based on substituted service are respectively proposed too. In order to verify the feasibility of the proposed technological test scheme, the testing system with the above technical characteristics is realized through the software technology, which includes relay protection and measurement & control information simulation system and main station simulation system. Finally, engineering application proves that station level test technology of smart substation improves testing efficiency and ensures the reliability of measurement results.
