C) assessment is analyzed to accident prediction：There is major accident or exception in the face of grid equipment for investigating student
In the case of, if can be processed due to equipment fault or abnormal caused consequence with most reasonable manner within the time of regulation.
Student's operation operation evaluation process, student's operation operation assessment stream are illustrated as an example with the transformer station shown in Fig. 2
Journey is shown in Fig. 1.
Fig. 2 is a typical 110kV transformer station, for the ease of description, 110kV partial wiring diagrams is only drawn here.It is false
L2 is powered on alignment road.
Fig. 2 only depicts the equipment such as inlet wire and the switch, the bus that are connected.It is related that system will automatically generate the wiring diagram
The working specification of equipment, here, we illustrate the generating process of working specification by taking the maintenance of circuit L2 equipment as an example.
For the maintenance of circuit L2 equipment, according to overhaul of the equipments specification, the switch of circuit measurement should be separated first, then
Separate bus end disconnecting link, then separately line side disconnecting link, finally close line-to-ground disconnecting link.Fig. 2 to Fig. 6 shows the plant stand this side line
Section operating procedure, plant stand offside equipment operation step is identical with this side plant stand.The maintenance of circuit L2 should be divided into 4 steps, and first
Step, separately switchs 102, as shown in Figure 3；Second step, separates bus bar side disconnecting link 102-1, as shown in Figure 4；3rd step, separates circuit
Side tool lock 102-2, as shown in Figure 5；4th step, close earthing 102-2-1, as shown in Figure 6.
It is exactly above the concrete steps that overhaul of the equipments operation is illustrated by taking circuit as an example.
To student's operation operation evaluation process as shown in figure 1, in training process, according to grid equipment operations specification will
Ask, all types traveled through in transformer substation system, the equipment of all electric pressures are formed one by one all devices each by training system

For working specification.
In training process, the such as teaching notes content of maintenance operation class, and the time for specifying to complete in teaching notes are read this moment
The interior real-time operation content for reading and recording student, requires according to five anti-operations, judges whether student's operation is maloperation, such as
It is maloperation that fruit judges, then a maloperation record for this training is automatically generated, while training system will deduct teaching notes
The maloperation score value of setting, the examination for the teaching notes terminates；If it is determined that not being maloperation, then the operation of contrast judgement student
Whether step is consistent with the corresponding working specification of the equipment in experts database, and student's working specification is automatically generated if inconsistent
The training record of mistake, while deducting the deduction of points value of teaching notes working specification mistake set in advance.
Above-mentioned each operation class teaching notes need the analysis and evaluation through above-mentioned steps, finally with teaching notes setting operation class total score
The fraction of working specification mistake deduction is deducted, student's operation operation assessment score value is obtained.If teaching notes setting operation class is total
It is divided into if 20 points, if student's operation is correct, this must be divided into 20 points of full marks, otherwise this must be divided into 20 and deducts operation
The fraction of deduction.

The related equipment of criticality of the coefficient major embodiment equipment in operation of power networks, such as Weak Node in Power Grid or key node is not
Permission is out-of-limit, so the safety loading coefficient of this kind equipment is just high, conversely, safety loading coefficient is just low, and according to the voltage of equipment in net
Grade, device type and out-of-limit degree, artificial batch defines the safety loading coefficient of whole network equipment；What coefficient of reliability embodied is negative
The significance level of lotus, according to the distribution situation of network load, load is generally divided into a type load, two type loads and three classes and bears
Lotus a, type load is mostly important, therefore coefficient of reliability is just high, and the significance level of three type loads is relatively minimum, therefore coefficient of reliability
It is minimum；Whether the operation of power networks of economic factor major embodiment is the most economical, reasonable, and economic factor is defined simultaneously by the requirement of user
Provide the economic examination threshold value that the whole network is lost under the conditions of acceptable.
With reference to shown in Fig. 7, before operation of power networks index evaluation is carried out, first have to manual maintenance and determine electrical network various kinds of equipment
