Embodiment
The system of locking prepared auto restart when the present invention realizes stability control device action cutting load, as shown in Figure 1, comprising:
Power end locking prepared auto restart communication interface, be installed in power end transformer station, the stability control device of Yu Gai transformer station is connected, for receiving the excision load line information that stability control device sends, to the load side locking prepared auto restart communication interface of corresponding load side transformer station, send locking prepared auto restart action message;
Several load side locking prepared auto restart communication interfaces, each load side locking prepared auto restart communication interface is installed in Yi Ge load side transformer station, the prepared auto restart of Yu Gai transformer station is connected, for receiving the action outlet junction closure of locking prepared auto restart action message rear drive relay, connect the electric discharge locked loop of load side prepared auto restart, realize the electric discharge locking of prepared auto restart.
Provided by the invention a kind of while realizing safety and stability control device action cutting load the system of locking automatic closing to have the application mode that 1 or 1 above Load Substation configured backup auto-activating device and load side locking prepared auto restart communication interface all applicable to similar.
Fig. 1 shows the typical application scenarios of 1 Yu16Ge of power end transformer station load side transformer station, power end locking prepared auto restart communication interface only needs 1, but it possesses 16 output communication ports, can be connected work with the load side locking prepared auto restart communication interface of 16 Load Substation.Fig. 2 is the workflow diagram of native system, below in conjunction with the further interpretation work flow process of example.
Safety and stability control device exemplary configuration as shown in Figure 1 16 pairs of tripping operation outlet contacts, corresponding access can realize the switch trip loop of 16 go back tos load circuits controlling cutting load respectively.During safety and stability control device action cutting load, to power end locking prepared auto restart communication interface, send the information of cutting load simultaneously.For example, according to the action policy of safety and stability control device, under certain manner of execution, need to take the measure of excision load circuit 1, load circuit 3, load circuit 4 loads, safety and stability control device, in action outlet jump load circuit 1, load circuit 3, load circuit 4 switches, sends excision load circuit 1, load circuit 3, load circuit 4 information to power end locking prepared auto restart communication interface.
By above-mentioned example, the communication module of power end locking prepared auto restart communication interface as shown in Figure 1 receives information by optical-fiber communication channel from the port of communicating by letter with safety and stability control device; The logic processing module of power end locking prepared auto restart communication interface is resolved the information receiving, obtain after the signal of excision load circuit 1, load circuit 3, load circuit 4, if the passage pressing plate of port one, port 3, port 4 correspondences drops into, to port one, port 3, port 4, send locking prepared auto restart action message immediately; If port one, port 3, the passage pressing plate that the arbitrary port of port 4 is corresponding exit, to this port, do not send any information.
By above-mentioned example, the communication module of the load side locking prepared auto restart communication interface of load side transformer station 1 receives information by optical-fiber communication channel from the port one of power end locking prepared auto restart communication interface as shown in Figure 1; The logic processing module of load side locking prepared auto restart communication interface is carried out anti-error verification to the information receiving, comprise CRC check and message address verification, be verified as the Executive Module to load side locking prepared auto restart communication interface when correct and send locking prepared auto restart action command; The Executive Module of load side locking prepared auto restart communication interface receives after locking prepared auto restart action command, the action of driving exit relay, again by the normal opened contact closure of exit relay to connect the discharge loop of transformer station's 1 automatic switching device of standby power supply, realize the object of locking prepared auto restart action.
By above-mentioned example, as shown in Figure 1 the communication module of the load side locking prepared auto restart communication interface of load side transformer station 3 by optical-fiber communication channel the port 3 reception information from power end locking prepared auto restart communication interface; The communication module of the load side locking prepared auto restart communication interface of load side transformer station 4 is the port 4 reception information from power end locking prepared auto restart communication interface by optical-fiber communication channel.The handling process of the load side locking prepared auto restart communication interface of load side transformer station 3, load side transformer station 4 after receiving locking prepared auto restart action message is consistent with above-mentioned load side transformer station 1, does not repeat them here.
By above scheme, can be found out, a kind of system of locking automatic closing while realizing safety and stability control device action cutting load of the present invention, by the information interaction between communication interface, the demand of reliable locking automatic closing while having realized safety and stability control device action cutting load.The method of locking automatic closing while realizing safety and stability control device action cutting load of the present invention, the Load Substation going for more than 1 or 1 needs the application form of locking automatic closing when safety and stability control device action cutting load, when needing the automatic closing of a plurality of load side of locking transformer station, only need install safety and stability control device action cutting load a set of power end locking prepared auto restart communication interface, and the connection between device adopts optical-fiber communication channel, save the investment of secondary circuit and device, improved the reliability of fail safe and the power supply of electrical network, there is good economic benefit.
The above embodiment has only expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
