Embodiment
For further setting forth the technological means that the present invention takes and the effect that obtains, below in conjunction with accompanying drawing and preferred embodiment, to technical scheme of the present invention, know and complete description.
See also Fig. 1, for the present invention is based on the schematic flow sheet of the relaying protection on-line monitoring method of protecting communication system.The present invention is based on the relaying protection on-line monitoring method of protecting communication system, may further comprise the steps:
S101 is by protecting the monitoring information class quantity of state of communication system Real-time Obtaining protective relaying device;
As one of them embodiment, described monitoring information class quantity of state is divided into monitoring information Regularia quantity of state, physical message Regularia quantity of state and Expert Rules class quantity of state according to Data Source.
The various amounts that can characterize the protective relaying device state are divided into following a few class according to the Data Source difference:
The monitoring information Regularia: the monitoring information evaluation rule is the rule that a class is estimated the equipment real time data, and the data that on-line monitoring is collected can find corresponding rule to estimate in the monitoring information evaluation rule.The self-checking alarming of the main monitoring and protecting of system and action.
Physical message Regularia: the rule that every Test Information, operational inspection information are estimated.This type of Bye-Law to Rule is more fixing, and trigger data also is to rely on manual entry, and rule definition is relatively simple.
The Expert Rules class: Expert Rules is the rule of estimating mainly for the familial defective, and the characteristics of this rule-like are to have uncertainty, also needs the professional to be confirmed whether equipment is estimated after being triggered.For example, two device trigger have been arranged same Expert Rules, but the expert may the operation of marking after analyzing in conjunction with actual conditions, and another has just ignored this rule.
Wherein monitoring information class quantity of state obtains by protecting communication system, can grasp in real time the state value of the protective relaying device of the whole network on-line operation, then marks according to its value.
S102 marks to the running status of protective relaying device according to the described monitoring information class quantity of state that obtains;
As one of them embodiment, respectively according to described monitoring information Regularia quantity of state, described physical message Regularia quantity of state and described Expert Rules class quantity of state to the protective relaying device scoring of classifying;
Sue for peace after the result of described classification scoring multiplied each other with default weight coefficient respectively, obtain the appraisal result to protective relaying device.
For example can adopt the dual scoring model of classification scoring and whole scoring, adopt bonus point system.
The classification scoring refers to mark respectively by monitoring information Regularia, physical message Regularia, Expert Rules class respectively, if the scoring of certain rule-like has surpassed threshold values, will not carry out the integral body scoring, directly is judged as unit exception, needs maintenance.
Whole scoring refers to the overall merit to Whole Equipment maintenance urgency: according to the partial status evaluation result, the bound fraction evaluation adopts suitable algorithm to draw Whole Equipment maintenance urgency grade to the influence degree of Whole Equipment function.For example, can mark according to following table.
