The relay protection substation is a hardware and software system which is installed at a power system station end and is responsible for communicating with secondary equipment such as an accessed relay protection device, a fault recorder and the like, completes protocol conversion, information collection, processing, control and storage, and sends information to a relay protection online monitoring control function module according to requirements.

The relay protection main station provides a unified online monitoring and control analysis platform for the relay protection and safety automatic device, and is beneficial to a power grid dispatching department to quickly master the actual fault condition of a power grid, the action behavior of relay protection and the system recovery condition through data linkage with the relay protection substation, so that the rapid analysis and implementation countermeasures of power grid accidents are realized. The online monitoring control function of the relay protection master station is beneficial to mastering the actual operation condition of the relay protection equipment and improving the dispatching operation management level. With the rapid development of intelligent wave recorder and fault on-line analysis technology and the establishment of power optical fiber data network, the practical application of the configuration checking module in the on-line monitoring control function of the relay protection main station becomes possible.

The substation testing function is used as a functional sub-module of the relay protection main station information protection system, and the functional sub-module comprises a substation inspection part and a substation acceptance part. The method for checking the uploading condition of the important information of the operated substation through the substation polling function mainly comprises the following steps: the device comprises a fixed value, a switching value, a soft pressing plate, an analog quantity, a communication state, a wave recording file list and a wave recording file. The sub-station checks and checks the various information uploading condition and configuration accurate condition of the new access sub-station, mainly comprising: the device comprises a fixed value, a switching value, an analog quantity, a soft pressing plate, a wave recording file list, a wave recording file, a communication state, a device software version, CRC (cyclic redundancy check), a device model and configuration check information.

The active information uploading test comprises events, alarms, fault amount and wave recording brief reports.

The existing substation testing function tests the important information uploading condition of the operated substation and various information uploading conditions and configuration accuracy conditions of the newly accessed substation through the substation polling and substation acceptance functions. With the increasing complexity of a power grid system, a substation test can set an inspection cycle according to actual needs, cycle calling and inspection are automatically started according to the set inspection cycle, if the communication state of the substation is disconnected, calling fails, the substation is automatically placed at the tail end of a queue, calling is performed on other substations after calling is completed, calling is stopped after the threshold value of the number of repeated calling is reached, and the threshold value can be configured. And after the inspection is finished, automatically generating an inspection report. The sub-station acceptance is judged by judging the selected sub-station, and the acceptance content of the 103/61850 sub-station is a fixed value, a switching value, a soft pressing plate, an analog quantity, a recording file list, a communication state and a device software version number; the acceptance content of the intelligent oscillograph is to call and analyze files.
