Embodiments of the present invention will be described below with reference to the drawings. The same parts as those in the conventional example are designated by the same reference numerals, and the duplicated description will be omitted.

Embodiment 1 FIG. 1 shows an embodiment of a plant simulation device of the present invention, which has a configuration in which, in addition to the conventional device shown in FIG. 13, a plant optimum value according to the state of each plant is stored. And a plant optimum value storage means 21, an operation evaluation means 22 for comparing and evaluating the simulated plant value from the plant simulation means 6 and the plant optimum value stored in the plant optimum value storage means 21, and this operation evaluation means.

Further, the simulator computer system 5a for simulating the plant and evaluating the operation includes an alarm simulating means 24 for simulating the alarm generation based on the operation signal 3, and a simulator clock 25.

The plant optimum value storage means 21 includes

In order to evaluate the deviation from the plant optimum value 31, which is the reference value of 7, the deviation calculator 33 calculates the deviation 34 between the simulated plant value 7 and the plant optimum value. Further, the maximum deviation 35 is calculated by the maximum deviation calculator 36 among the deviations 34 calculated by the deviation calculator 33 during the simulated operation. Furthermore, by the allowable value deviation number calculation unit 37,
In order to compare the simulated plant value 7 with the allowable value 32 of the plant optimum value and to check how many times the simulated plant value 7 deviated from the allowable value 32 during the simulated operation, the allowable value deviation number 3

More specifically, the operation of this embodiment will be described by taking as an example a simulated operation from the start of the rise in the main steam temperature of the power plant to the end of the rise in the main steam temperature.

FIG. 3 shows the main steam temperature rise rate from the start to the end of the main steam temperature rise due to the simulated operation. In this figure, the broken line 51 shows the simulated value of the main steam temperature rise rate, the solid line 52 shows the optimum value of the main steam temperature rise rate set in advance, and the alternate long and short dash line 53 shows the allowable value which is the allowable range from the optimum value. ing.

In a power plant, as shown in FIG. 4, for example, from start-up to 100% rated power generation, operation modes such as condenser vacuum rise start and 100% rated power generation can be classified. The time T from the start of activation is set in these operation modes. Plant optimum value storage means 21
In, the plant optimum value 31 and its allowable value 32 are registered in advance for each operation mode. For the operation modes of starting the main steam temperature rise and ending the main steam temperature rise, see FIG.

The plant optimum value 31 such as the main steam temperature and the allowable value 32 of the plant optimum value are registered.

The time required from the start time Ti of the main steam temperature rise to the end time Tj of the main steam temperature rise is determined by the constraints of plant operation. From the optimum value of the main steam temperature increase rate and the allowable value thereof respectively registered, the optimum value 52 and the allowable value 53 of the main steam temperature increase rate from the start of the main steam temperature increase to the end of the main steam temperature increase are calculated.
In the example shown in FIG. 3, the optimum value and the allowable value of the main steam temperature rise rate are the same values at the start and the end of the main steam temperature rise, and a linear function of the time from the start of the main steam temperature rise to the end of the main steam temperature rise. Therefore, the optimum value 52 and the allowable value 53 of the main steam temperature rise rate are indicated by a straight line.

In the simulated operation, the operator operates the operation switch 2 of the control panel 1 to increase the amount of fuel or air in order to increase the temperature of the main steam. Based on the operation signal 3, the plant simulation means calculates the simulated value 51 of the main steam temperature increase rate. In FIG. 3, the difference between the simulated value 51 of the main steam temperature rise rate and the optimum value 52 of the main steam temperature rise rate from the start of the main steam temperature rise to the end of the main steam temperature rise is the deviation 54, and the maximum absolute value thereof is The value is the maximum deviation 55.

The number of deviations of the simulated value 51 of the main steam temperature rise rate from the allowable value 53 is calculated by the method shown in FIG. In step 1, the allowable value 53 of the main steam temperature increase rate at a certain time Ti + Δt during the main steam temperature increase simulation operation is calculated by the above-described method, and at the same time calculated by the plant simulation means 6 A simulated value 51 of the main steam temperature rise rate is input (step 2). In step 3, it is determined whether or not the simulated value 51 of the main steam temperature rise rate at time Ti + Δt deviates from the allowable value 53, and if it deviates, the allowable value deviation frequency is counted in step 4. Up. The processing from step 1 to step 4 is repeated during the main steam temperature rise simulation operation from the main steam temperature rise start time Ti to the main steam temperature rise end time Tj, and the count number during that time is output as the allowable value deviation count. (Step 5). If the number of deviations from the permissible value is 0, there is no problem in the driving skill of the operator.

In addition to the above-mentioned allowable value deviation frequency, the operation evaluation means 22 similarly applies to the main steam temperature increase rate deviation 54 and the main steam temperature increase rate maximum deviation 55 for comprehensive evaluation. Calculated and output to the instructor console 9 by the driving evaluation result output means 23,
The collected operation history data 39 and alarm history data 41 are also output. From this evaluation result, it is possible to know which operation of the operator was wrong and how to perform the corresponding operation. In addition, even after a long period of simulated driving, the evaluation record can be left as a printout or a hard copy of the CRT, so that the operator can be instructed, and the simulated driving can improve the efficiency of the training. it can.

FIG. 7 shows an application example of the above embodiment, in which the actual plant value 62 from the actual plant system 61 is shown.
Is input to the operation evaluation means 22 of the above-mentioned embodiment, and the operation efficiency of the actual plant can be evaluated.

In this configuration, the actual plant value 62 from the actual plant system 61 is input to the simulator computer system 5a and compared with the plant optimum value 31 registered in the plant optimum value storage means 21 to evaluate the operation evaluation means. At 22, the actual plant is evaluated. The evaluation result of the actual plant is output by the operation evaluation result output means 23. This makes it possible to effectively improve the operation of the actual plant.
