2) the soft pressing plate of GOOSE on the protective device body; intelligent protection device (comprise protecting and survey integrated device) all is provided with GOOSE and sends (reception) soft pressing plate; withdraw from corresponding pressing plate later on corresponding GOOSE link will interrupt, no longer send (reception) accordingly GOOSE message (comprising heartbeat message).Concrete pressing plate is set to: the soft pressing plate of GOOSE tripping operation outlet, and the control protection is tripped by intelligent terminal; GOOSE starts malfunctioning soft pressing plate, starts female mistake spirit function; The GOOSE reclosing exports soft pressing plate, and the control protection is closed a floodgate by intelligent terminal; GOOSE receives soft pressing plate, and GOOSE corresponding to control opens into reception.
3) maintenance pressing plate, intelligent protection device and intelligent terminal all are provided with one " protection inspecting state " hard pressing plate, and this pressing plate belongs to adopt to open to throw into the function of mode and moves back pressing plate.When this pressing plate dropped into, the TEST place value of all GOOSE messages that related device sends was TRUE, as shown in Figure 3.
When if protective device drops into " protection inspecting state " pressing plate, also be with the maintenance position in the GOOSE message that protective device sends; If the state consistency of the inspecting state of intelligent terminal and protective device namely is the maintenance attitude or all is not the maintenance attitude, then intelligent terminal is processed the GOOSE message of protective device, allows the operation outlets such as breaker tripping and closing; If the state of the inspecting state of intelligent terminal and protective device is inconsistent, namely a side is not the maintenance attitude for maintenance attitude opposite side, does not then process the GOOSE message of protective device.
Consider that repeatedly the plug meeting is to increasing light mouth attenuation, pollution even destroy the light mouth for optical fiber port, so the optical fiber plug can not be arranged long-term use as a kind of peace.And the realization of the soft pressing plate of GOOSE and maintenance pressing plate all depends on the software of device, and the visual means reliability of software will become peace and arrange the deciding factor of reliability.If in the situation that reliability of software can not reach 100%, any single a kind of peace is arranged and all can't effectively be guaranteed to pacify arrange 100% reliable.Therefore can only rely on the soft pressing plate of GOOSE and the dual peace of maintenance pressing plate to arrange to mix and make to improve the reliability that peace is arranged enforcement.
