The association of measurement amount and switching value is described in detail below.

One, the association of measurement amount:

Existing SCD is analyzed, is by the Data induction that combining unit is sent:Specified delay, zero-sequence current, three-phase electricity galvanic electricity Pressure, synchronous voltage, gap current.

Specified delay, zero-sequence current in combining unit can be detached from model element, indirect assignment;

Output parameter value in combining unit reading model element takes away the three-phase output current instantaneous value of pass as electric current Value takes away the instantaneous voltage for closing the busbar that is connected as voltage value, takes the phase sequence, phase, voltage value of Switch Three-Phase as the same period Voltage value;

From the angle of transformer combining unit, directly to gap current assignment.

The relationship of combining unit and the output quantity of primary equipment is configured, the electric current of switch, voltage is corresponding with combining unit Channel be associated.Its cardinal principle is as follows:

From the DA (except daName=t/q) filtered out in smv_base under the combining unit, according to smv_id, seq liters Sequence arranges display in lists.

Obtaining current value on switch out of interval.Judge three according to DA descriptions and DO titles in combining unit SV data sets The correspondence of phase current takes away pass A phase i end output currents and is associated with current value DA.It is used herein as electric current and voltage Split-phase interpretation algorithm.What is start with " Amp " containing " electric current " printed words or doName in description is electric current, contain " voltage " printed words or What doName was started with " Vol " is voltage;In description and DO names, the corresponding A containing A/B/C letters/B/C phases.

According to the topological relation of a model, its busbar being connected with the ends i is searched, busbar A phases is taken to export transient voltage It is associated with voltage value DA.

By the measurement parameter information of configuration with after optional primary equipment output quantity is associated in present interval, sampled value ginseng Number is saved in jaxb_smv_baseda tables, and switch parameter is saved in jaxb_gse_baseda tables, and interval information is saved in In jaxb_bay tables.

Two, the association of switching value:

Position of the switch information is acquired by intelligent terminal, the protection being sent in present interval and measure and control device.One intelligence Terminal acquires the location information of a switch or multiple disconnecting links, these are switched, the information of disconnecting link is sent out by variable amount of data set It send.

Primary system obtains position of the switch information, needs the GOOSE numbers for subscribing to the on off state that parsing intelligent terminal is sent According to collection, and DA in data set is associated with the upper of switch when switch supports single-phase be separately controlled and is associated with out different DA Close ABC it is each it is single-phase on.

The description of switch and two model logic nodes (LN) of disconnecting link, is the data set of XCBR and XSWI respectively.Pass through solution Logical node in each mounted cast is analysed in SCD, and logical node is screened, extracts the logical node of switch and disconnecting link simultaneously It is shown with tabular form, the corresponding parameter once switched is matched.

The present invention is associated with by first and second system model, has got through the information channel of a pel and secondary model, and is System emulation lays the foundation, while will realize quick XML super larges document analysis i.e. by JAXB and VTD-XML technologies SCD is parsed, and the software algorithm of the association search based on graph theory realizes high visualization automatic mapping function simultaneously.In conjunction with two kinds of skills High visual intelligent transformer station secondary system can be shown by art, system diagram, logic connectivity diagram be presented automatically, in conjunction with intelligence The actual conditions stood are modified to automatic mapping content, are adjusted, and meet on-site actual situations and close friend is presented to user, real Figure, library, mould integration are showed.It can be taken over seamlessly between each figure layer, by invisible between IED, impalpable communication process with " virtual The form of secondary circuit " is presented, while critical event dynamic in the form of height is visual shows.

The above is the preferred embodiment of the present invention, for those skilled in the art, Without departing from the principles of the invention, several improvements and modifications can also be made, these improvements and modifications are also regarded as this hair Bright protection domain.
