Fig. 2 is converting station electric power device action rule base tracing trouble process flow diagram;

Fig. 3 is converting station electric power equipment monitor information representation case library tracing trouble process flow diagram.

Embodiment

Below in conjunction with accompanying drawing, the embodiment of the present invention is further described.

A supervisory control of substation information intelligent diagnostic analysis method, as shown in Figure 1, comprises the following steps:

Step 1, collection transformer station's real time monitoring information typing basic data database.

It is storage unit that this step be take the power equipment monitoring, supervisory control of substation information data is entered into respectively in basic data database, for the case work of obtaining provides data supporting.

Step 2, set up converting station electric power device action rule base, this action rules storehouse by converting station electric power equipment knowledge base with and annexation inference engine storehouse form.

As shown in Figure 1; in this step; by regulation management maintenance module, set up the rule base of the major equipments such as bus rule base, transformer rule base, line rule storehouse; using the protection information of the monitor message gathering and power equipment action as driving input; press the dependency rule in inference strategy calling rule storehouse; if the condition part of rule matches with diagnosis input message; this rule is put into candidate queue as applicable rule; by Rule of judgment conflict resolution, the condition using it as further reasoning is served final diagnostic result again.

Described knowledge base consists of power equipment physical attribute, electrical connection attribute and power domain professional experiences.The form of implementation rule is: if < prerequisite > is < action > so, during executing rule, premise part and rule database are carried out to information matches, once the match is successful, the action part of executing rule; Otherwise, do not respond.

Step 3, set up converting station electric power equipment monitor information representation case library, this information representation case library is integrated and is formed by the monitor message of enumerating the substation field collection of formula.

Information representation case library is that case management maintenance module is usingd the data of electrical equipment fault problem as raw data, by the analysis of raw data, sets up fault analysis case archives.As shown in Figure 2, case management maintenance module is obtained Inference Conditions from rule base, foundation using it as Case Retrieval, if case coupling, carry out the multiplexing acquisition diagnostic result of case, if coupling case is unsuccessful, start the rule base matching process of a new round, form new analysis case, finally obtain diagnostic result.
