Interlock inference service device: the real time data of being responsible for described communication server to receive is carried out reasoning, if real time data meets predefined interlock logic, searches the empty remote signalling of its correspondence, and exports this void remote signalling;
Server is carried out in interlock: be responsible for according to the empty remote signalling of described interlock inference service device transmission, convert thereof into after the action command of controlling the auxiliary comprehensive monitoring system of described intelligent substation and Substation SCADA System, action command is controlled the auxiliary comprehensive monitoring system of described intelligent substation and Substation SCADA System according to this.
Preferably, the auxiliary comprehensive monitoring system of described intelligent substation comprises video, gate inhibition, security protection, fire-fighting, environmental monitoring, air conditioner ventilation, illumination and on-line monitoring one of them or multiple watch-dog.
Preferably, described interlock logic comprises the matching condition of described empty remote signalling and described empty remote signalling, if described real time data meets the matching condition of described empty remote signalling, described interlock inference service device is carried out server to described interlock and sent described empty remote signalling.
Preferably, the matching condition of described empty remote signalling comprises the time sequencing of equipment state, warning information, remote measurement value and a plurality of warning information acquisition times.
Preferably, described interlock inference service device provides human-computer interaction interface, for operating personnel, safeguards described interlock logic.
Preferably, described interlock execution server receives after the empty remote signalling of described interlock inference service device transmission, first search the interlock corresponding with it and carry out prediction scheme configuration file, then convert thereof into the action command of the auxiliary equipment of controlling the auxiliary comprehensive monitoring system access of described intelligence, and can trigger siren and send note, mail to related personnel.
Preferably, described interlock is carried out server human-computer interaction interface is provided, and for operating personnel, safeguards described interlock execution prediction scheme configuration file, and prediction scheme configuration file is carried out in described interlock and described empty remote signalling is mated one by one.
Preferably, described interlock execution prediction scheme configuration file is XML form.
The beneficial effect that the present invention reaches: give full play to the advantage of smart machine, in conjunction with on-line monitoring and environmental monitoring, can just take interlock measure to eliminate potential faults before equipment breaks down, and remind operations staff to pay close attention to; After breaking down, can change the mode that after breaking down, substation operation personnel manually carry out in the past, greatly improve the efficiency of troubleshooting.In addition, intelligent linkage, to improving fail safe, the reliability of substation operation, reduces the aspects such as energy consumption all significant.For unattended operation transformer station, this function is very necessary especially.

Embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of Intelligent interlocking system of transformer substation of the present invention comprises that intelligent substation assists comprehensive monitoring system, Substation SCADA System, communication server, interlock inference service device and interlock to carry out server, and wherein the auxiliary comprehensive monitoring system of intelligent substation can comprise the subsystems such as video monitoring that access controller, environmental monitoring, on-line monitoring, security protection, fire-fighting, illumination, air conditioner ventilation and DVR (DigitalVideoRecorder: i.e. digital video recorder) form as required.Communication server receives from the auxiliary comprehensive monitoring system of intelligent substation and passes the real time data of coming, and by obtaining SCADA data from Substation SCADA System.Interlock inference service device is responsible for, according to interlock logic, real time data is carried out to reasoning, satisfies condition the reasoning results, i.e. empty remote signalling sends to interlock to carry out server.Interlock is carried out server according to empty remote signalling, read in corresponding interlock and carry out prediction scheme, and interlock is carried out to prediction scheme convert action command to, and automatically control according to this auxiliary equipment of the auxiliary comprehensive monitoring system access of described intelligence, and can trigger siren and send note, mail to related personnel.
As shown in Figures 2 and 3, interlock inference service device provides human-computer interaction interface for the interlock logical definition table in operating personnel's maintenance system database, and the configuration tool that also can provide by system generates interlock logic.Whether every interlock logic is comprised of empty remote signalling, some conditions and state, also can select according to time sequencing, to judge.Every empty remote signalling can configure the interlock execution prediction scheme configuration file of an XML form, and this document has defined concrete interlock type and interlock entity, and it can carry out server by interlock provide human-computer interaction interface to generate.
Interlock inference service device when starting, can first load all interlock logical definition tables in all interlock logics, then regularly collect the real time data that communication server sends, according to the condition in interlock logic, the empty remote signalling that search criterion meets.If this void remote signalling has configured interlock and carried out prediction scheme configuration file, send this document name and carry out server execution to interlock.If certain remote signalling or remote measurement are a condition of certain interlock logic, and its value or state meet rule, whether other condition that constantly detects (5-10 second) this interlock logic in a specific time window meets, and the interlock prediction scheme configuration file of getting the empty remote signalling association of its interlock result as met sends to interlock to carry out server and carries out.
Interlock is carried out server after receiving the execution request of interlock prediction scheme configuration file, according to difference interlock type, sends to the service processes of different sub-systems to carry out.Interlock type is divided into that remote control is outputed, alarm bell siren, phonic warning, video interlink, gate inhibition's interlock, SMS notification, mail notification etc.The remote control referring to auxiliary equipment is outputed in remote control, comprises switch lamp, switch gate, startup blower fan, starts draining etc., and service processes is carried out in interlock can send to this type of remote controlled point of configuration the execution of remote control service processes.Alarm bell siren type can trigger transformer station's alarm bell or siren.Phonic warning can trigger the audio files of playing phonetic synthesis.Video interlink is divided into real-time video and grabgraf, can enable respectively, if real-time video is provided with preset point, can also forward relevant position to by linkage camera.The related service execution that service processes can send to video interlink subsystem of video is carried out in interlock.Gate inhibition's interlock refers to that in case of emergency removing access controller authority differentiates.Service processes is carried out in interlock can all send to the access controller ID arranging in prediction scheme gate inhibition's subsystem related service execution.SMS notification and mail notification can send to associated user by fault or abnormal conditions and interlock implementation status and organize whole members or certain user.
