For ease of understanding the present invention, below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.

Dispatcher training analogue system (hereinafter to be referred as training system) is a set of computer system, it is by the mathematical model of simulated practical power systems, simulate the system condition after various scheduling operations and fault, and these information are delivered in the model of Power System Control Centers, for yardman provides a Training Environment true to nature, to reach the object that neither affects the operation of practical power systems and training yardman, the functipnal capability of yardman under normal condition and quick-reaction capability (QRC) under accident condition have been trained, also can be used as the instrument that dispatching of power netwoks operations staff analyzes operation of power networks.

The invention provides a kind of method of student's operation being carried out intelligent evaluation in dispatcher training analogue system, comprise following three kinds of situations:

A) student's operation is assessed: for investigating that student carries out for grid equipment that instruction issues or during straighforward operation, whether student's operation is maloperation, and investigates the requirement whether student's operation meets grid equipment operation standard; Wherein maloperation comprises that on-load broaching tool lock, on-load close disconnecting link, the charged ground wire etc. that closes;

B) operation of power networks index is assessed: for investigating student, control the ability of operation of power networks quality, operation of power networks index comprises the economic index of the safety indexes of operation of power networks, the reliability index of operation of power networks and operation of power networks;

C) accident prediction is carried out to analysis and evaluation: for investigating student in the face of in grid equipment generation major accident or abnormal situation, whether can be in official hour with reasonable manner, process due to equipment failure or the consequence that extremely causes.

With the transformer station shown in Fig. 2, student's operation evaluation process is described as an example, student's operation estimation flow is shown in Fig. 1.

Fig. 2 is a typical 110kV transformer station, for convenience of description, only draws 110kV partial wiring diagram here.Suppose that circuit L2 is charged.

Fig. 2 has only drawn the equipment such as inlet wire and the switch connecting, bus.System will generate the working specification of this wiring diagram relevant device automatically, and here, we take the maintenance of circuit L2 equipment is example, illustrates the generative process of working specification.

For the maintenance of circuit L2 equipment, according to overhaul of the equipments standard, first should separate the switch that circuit measures, then separate bus end disconnecting link, then strapping wires trackside disconnecting link, line-to-ground disconnecting link finally closes.Fig. 2 to Fig. 6 shows this this side line of plant stand section operation steps, and plant stand offside equipment operating step is identical with this side plant stand.The maintenance of circuit L2 should be divided into 4 steps, and the first step is separated switch 102, as shown in Figure 3; Second step, separates bus bar side disconnecting link 102-1, as shown in Figure 4; The 3rd step, strapping wires trackside disconnecting link 102-2, as shown in Figure 5; The 4th step, the earthing 102-2-1 that closes, as shown in Figure 6.

More than take exactly the concrete steps of circuit as example devices illustrated inspection operation.

To student's operation evaluation process as shown in Figure 1, in training process, according to the requirement of grid equipment operations specification, training system is by all types in traversal transformer substation system, the equipment of all electric pressures, form one by one the various types of working specifications of all devices, and equipment, action type and working specification are preserved, generate grid equipment working specification experts database.Grid equipment working specification experts database comprises the be incorporated into the power networks bypass replacement working specification of working specification and equipment of all kinds overhaul of the equipments working specification, all kinds equipment cold standby working specification, all kinds equipment stand-by heat working specification, all kinds equipment.

In training process, read this moment as the teaching notes content of the class of operation such as maintenance, and in the time of having stipulated at teaching notes, read in real time and record student's content of operation, according to five anti-operation requirements, judge whether student's operation is maloperation, if judge it is maloperation, automatically generate one for the maloperation record of this training, the maloperation score value that simultaneously training system will deduction teaching notes be set, finishes for the examination of these teaching notes; If judge it is not maloperation, whether the working specification that in contrast judgement student's operation steps and experts database, this equipment is corresponding is consistent, if inconsistent, automatically generate the training record of student's working specification mistake, deduct the deduction of points value of the predefined working specification mistake of teaching notes simultaneously.

Above-mentioned each class of operation teaching notes need the analysis and evaluation through above-mentioned steps, finally by teaching notes setting operation class total points, deduct the mark of working specification mistake deduction, obtain student's operation and assess to obtain score value.If teaching notes setting operation class total points is 20 minutes, student operates accurate words, and this must be divided into full marks 20 minutes, otherwise this must be divided into 20 marks that deduct operation deduction.

Economy examination must be divided into: economic evaluation item total points-E _s.

6. method of student's operation being carried out intelligent evaluation in training system according to claim 1, is characterized in that, described c) accident prediction is carried out to analysis and evaluation comprise the following steps:

(c-1) make accident prediction, extract the whole accident teaching notes in teaching notes, and formulate detailed accident treatment prediction scheme according to the concrete accident of teaching notes, and define every kind of given score of processing prediction scheme, the last mode with prediction scheme file and accident teaching notes information bundle preserves;

(c-2) in training process, in-service monitoring student is triggered to all operations in the accident predetermined processing deadline from accident, read the accident teaching notes of current time, and student's operation is analyzed with accident prediction, whether the mode that detects comparison student processing accident meets a kind of in accident prediction, if so, record the given score of this accident pretreating scheme; If do not meet any one accident prediction, this accident treatment assesses to such an extent that be divided into zero;

(c-3) after training finishes, calculate the PTS of accident prediction analysis item, specific formula for calculation is as follows:

Wherein, S _sfor teaching notes accident treatment PTS, k is teaching notes total number of accident, S _ifor student processes the score of i accident of teaching notes.
