Specific embodiment
It is further to carry out combined with specific embodiments below in order to more clearly describe technology contents of the invention
Description.
The method that the judgement processing of substation operation rate should be realized based on secondary device communication state of the invention, substation point
It is not connected with substation operation monitoring system and secondary equipment, including following steps:
(1) substation passes through the network-in-dialing state of substation operation monitoring system and secondary device, obtains secondary device
Operation ratio；
(1.1) substation judge substation operation monitoring system communication state whether be it is disconnected, if it is, substation
Operation ratio is 0%；Otherwise, continue step (1.2)；
(1.2) substation obtains the operation ratio of affiliated secondary device by judging secondary device communication state；
Supervision equipment described in (1-1.1) judges to work as by the connection status of the network or data line that monitor secondary device
Whether preceding device is in operating status；
(2) substation operation state is obtained by the operation ratio that the secondary device communicates.
As the preferred embodiment of the present invention, the operation ratio of secondary device is calculated in the step (1.2), specifically
Are as follows:
The operation ratio of secondary device is calculated according to the following formula:
In a specific embodiment of the invention, the judgement of the data of substation operation state is derived from, belonging to secondary set
Standby communication operating condition can be obtained substation by the operation ratio to the secondary device communication accessed under statistics substation
Operating status, the final real-time monitoring realized to substation's state.
As shown in Figure 1, access numerous secondary device devices under each substation, by secondary belonging under substation
The operational effect of current substation is defined in the judgement of the communication state of apparatus；Secondary device is connect under substation, above connects change
Power station operation monitoring system is monitored using all substations that substation operation monitoring device can access it.
Two aspects of judgment basis main source of substation operation situation, first is that the secondary device dress accessed under substation
The communication condition set；Second is that substation communicates the substation operation monitoring system of upper access；Substation is secondary to lower access to be set
Standby communication state, be broadly divided into two states: on/off, identical substation are also classified into upper incoming communication state: on/off；
The evaluative meaning of substation operation state, which is that, instructs station, specifies more reasonable Strategies of Maintenance, section
About manpower and material resources improve working efficiency；By substation operation state evaluation, the state of substation is quantified, with number
Formal intuition the operating status for representing substation.
Method 1: substation to lower by judging secondary device communication state, obtain belonging to secondary device operation ratio,
Its calculation method is
Method 2: substation, by judgement and substation operation monitoring system communication state, breaks on if current state is shown
Then, the operation ratio for defaulting substation is 0%, if display is logical, needs the operation ratio for going to judge substation according to method 1.
This programme is mainly to pass through Industrial Ethernet or universal serial bus to connect the cable between substation and secondary device
Whether be normally foundation, corresponded to N number of secondary device under each substation if connecing, by logical to substation and secondary device network
Letter is normal/and the state that disconnects judges, the availability of current transformer substation, the finger of its monitoring of supervisory control of substation secondary device monitoring equipment
Mark the link on off operating mode that information is network.
As shown in Fig. 2, protective device/wave recording device (or other secondary devices), is accessed by Ethernet/serial bus
The supervision equipment of transformer substation end, supervision equipment are by monitoring its network/data line connection status judge present apparatus
It is no in operating status.
The calculating of the operation ratio of this programme is mainly counted by the state of the network-in-dialing to statistics access device,
Statistics before did not had using the on-off of network as an evaluation criterion, and in new statistical method, added to " power transformation
Stand " and " substation operation monitoring " network connection judgement, when " substation " and " substation operation monitoring " network channel break
It opens, the operation ratio that default is somebody's turn to do " substation " is 0%.
As shown in figure 3, " substation " such as " becomes the lower multiple secondary devices of access to upper connection " substation operation monitoring "
Power station operation monitoring " and the state of " substation " network connection are to disconnect, then count default " substation " (as shown in Figure 2) under
All secondary devices of access are connected as that network is obstructed, and operation ratio shows 0%.
It is clear using the method for the invention for realizing the judgement processing of substation operation rate based on secondary device communication state
The standard for realizing the monitoring of substation operation rate, realizes controllableization of the operational monitoring data of substation, specifies substation
Operation data quantization measure.This method is intimately associated a kind of completely new solution party of substation secondary device condition monitoring
Case, it is therefore an objective to be counted by the communication state of the secondary device under analysis substation, to judge the operating status of substation；It realizes
The real time monitoring of substation operation state improves the working efficiency of substation's fortune inspection, to realize that the maintenance of substation provides effectively
Guarantee and foundation.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that can still make
Various modifications and alterations are without departing from the spirit and scope of the invention.Therefore, the description and the appended drawings should be considered as illustrative
And not restrictive.
