Described state model and Controlling model are shown by visual interface, and described state model is general information, exposing operational state information, also realize suspending and continuing operation to sequential control simultaneously; Described Controlling model shows concrete operating procedure according to the requirement of operation order, and each operating procedure only shows practical operation information, does not directly show concrete configuration.
Unified standard and definition are carried out in the requirement that IEC61850 standard extension followed by the model of state model; The content of Controlling model derives from the configuration on backstage completely, and namely backstage connects the specifying information of each equipment obtained of entirely standing, and from these information, directly chooses the data attribute required for sequential control, realize flexible configuration and the unrestricted choice of sequential control.
Its essence of the configuration of Controlling model uses the existing model in full station, but in order to the convenience shown, the content of model does not directly show on interface, but show concrete operating process according to the content of operation order, divide into two parts in the configuration of this Controlling model, one is external display description, and one is the configuration of model.Namely the operating procedure of interface display is the content of operation order, and the mode by manually inputting fills in concrete content of operation, and the interface also by operation ticket system and sequential control function obtains operation order content.The concrete information model of concrete operative association is walked afterwards for each, for the straighforward operation of the primary equipment such as circuit breaker, isolating switch, its concrete information model is structure, obtained device model is associated with full station equipment by background monitoring system, find the control logic node of logical device (LD) in the concrete IED involved by operation, the structure type SBOw of logical node, Operate, Cancel are added in the single-step operation wherein related to, and then forms the structure content of single-step operation in sequential control.It is also that the model obtained by background monitoring system is directly associated that move back for soft pressing plate throwing, customised regions switching etc. operates, and because sequence control system can cross-platformly realize, for this reason, final model needs manual adding wherein.
After Controlling model completes, final operative configuration is also formed, and total operating procedure is also determined, and now, in stateful configuration model, overall operation step just can accurately show.Correct for guaranteeing that model configures, emulated by analogue system, to guarantee the consistent of actual disposition and schedules operations, the practical operation of accurate rear beginning sequential control to be configured.
Clicking operation starts, the flow process that can control in order carries out operation progressively, system can detect the latching logic of each single-step operation automatically, only have conditions permit just to control concrete operation, if be now configured with video interlink signal, then can send interlock signal, guarantee that video frequency pick-up head is switched to by the equipment operated, realize the real time monitoring to operating equipment, start to perform actual control operation while sending interlock signal, every successful execution single stepping, (successful execution number of steps/total number of steps that current state in state model will show, as: 2/6, successful execution 2 step, total step number is 6).If break down in operation failure, operation overtime, operating process, sequential control meeting emergent stopping, and show error reason.
In operation, if operating personnel run into special circumstances, can realize suspending control to sequential control operation according to the reality of self, continuation operation is restarted after conditions permit, the operating procedure that now sequential control can continue according to configuring before operates, to meet the diversified demand of substation operation maintenance.
Associative operation due to transformer station is mostly similar operation, therefore sets up typical operation repository by this sequence control system, is about to conventional operation and associates with the model of relevant device.Transformer substation system, at the beginning of Installation and Debugging, can be set up by way of manual operation.First set up the repository of the primary equipments such as each circuit breaker, isolating switch, then set up but the repository at interval according to the actual construction of transformer station; Afterwards after transformer station puts into operation according to the accumulation of multi-pass operation, progressively set up the repository of each operation, and then convenient calling from now on generic operation.When running into new sequential control operation, the mode by combination configuration realizes, and namely from existing storehouse, calls similar configuration, carries out cutting based on this, and combination new needs manually adds, and carries out forming new sequence operation flow process.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or equivalent replacement, and not departing from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the middle of right of the present invention.
