Embodiment Construction

[0037] The soft pressure plate of the secondary device of the smart substation, especially the soft pressure plate of the relay protection device, is directly related to the normal operation of the secondary system. The protection function soft pressure plate directly determines whether the function of the device is put into operation; the outlet soft pressure plate directly determines whether the GOOSE jump / close or control command can be issued after the logical action of the device function; the receiving soft pressure plate, especially the SV receiving soft pressure plate, directly determines Whether the signal received by the device is complete, which leads to whether the function of the device can operate normally. Therefore, the incorrect operation of the device's soft pressure plate may lead to the lack of function of the device, abnormality or failure to issue the GOOSE command correctly, which will lead to the incomplete protection function of the secondary system for...

Abstract

The invention discloses an equipment real-time status-based smart substation soft strap remote anti-misoperation method. According to the method, whether soft strap remote control operation is allowed is judged based on the real-time status of primary equipment and functional completeness of secondary equipment and according to principles that the primary operating equipment cannot operate without main protection, 220kv-or-above equipment cannot operation without failure protection, and a tripping switching-on protection device cannot operate a SV receiving soft strap, if the soft strap remote control operation affects the main protection and the completeness of the failure protection of the primary equipment, the soft strap remote control operation is prohibited. The method of the invention, based on real-time status information of a substation, can prevent potential safety hazards about main protection-free operation or failure protection-free operation of the primary equipment brought about by misoperation of a soft strap, and can also prevent potential safety hazards about incorrect action brought about by the misoperation of the soft strap, and can improve the operation accuracy of the soft strap and ensure safe and reliable operation of the smart substation.

Description

technical field [0001] The invention relates to a remote misoperation prevention method for a soft pressure plate of an intelligent substation based on the real-time state of equipment, and belongs to the technical field of electric power automation. Background technique [0002] The digitization and networking of information in smart substations has replaced a large number of cable loops with optical fiber loops, and the structure of the relay protection device at the interval layer has changed. The original hard pressure plate for the exit has been replaced by a soft pressure plate for the exit. In order to avoid the influence of abnormal digital information, the relay protection device has added a receiving soft pressure plate, which can effectively isolate abnormal SV information and GOOSE information. With the application of IEC61850, the functional pressure plates of intelligent or conventional relay protection devices are gradually transformed into soft pressure plate...
