[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving training simulator for training a driving operator such as a power plant.

[0002]

2. Description of the Related Art FIG. 3 shows, for example, JP-A-60-230182.
In the figure, 1 is a simulated control panel for operating auxiliary equipment and equipment of a plant, and 2 is a simulator for processing signals operated by the simulated control panel 1. A computer for computing the behavior on the plant side with respect to the operation, 3 is an instructor's desk for operating a simulation device composed of the simulation control panel 1 and the computer 2, and 4 is an environmental condition detection device connected to the computer 2. Figure 4 shows a circuit that switches between the stored environmental conditions data and the environmental conditions detected from the actual plant. 31 is the data that stores the environmental conditions, and 32 is the variable attached to one of these data. Name HZSET, 33 is a variable name HZDET attached to one of the data detected by the environmental condition detecting device 4, 34 is a condition determiner by software, 35 is a variable name HZ attached to the output data of the wave condition determiner 34, that is, Indicates the value of environmental conditions.
Reference numeral 36 is a dynamic characteristic model for calculating the dynamic characteristics of the plant using the environmental condition 35 as one of the input data.

Next, the operation will be described. The environmental condition detected by the environmental condition detecting device 4 is input to the computer 2 and processed as an input variable HZDET33. Either the data HZSET32 storing the environmental conditions or the detected data HZDET33 is selected by the condition determiner 34 and becomes a variable HZ35, which is given to the dynamic characteristic model 36. The input variable HZDET is a value that changes from moment to moment, and by using this value, a very realistic state can be simulated and the operating state under external environmental conditions can only be simulated. Instead, it is also possible to display external environmental conditions that change depending on the chance. Environmental conditions of the plant operation training simulator include the outside air temperature, humidity, cooling water temperature, power system voltage, and frequency. For example, the actual frequency is detected by the environmental condition detecting device 4, is input to the computer 2, and is used as the environmental condition data, so that the operation training is performed as if the actual plant is operating under exactly the same environmental condition. It can be performed.

Further, when it is desired to perform training assuming a condition different from the external environmental condition at the time of carrying out the training (for example, when assuming the condition of winter in summer), the environmental condition that can be arbitrarily set by the condition judging unit 34. By selecting the setting data 31 and giving it to the dynamic characteristic model 36 and performing a simulated calculation, it is possible to carry out driving operation training under specified environmental conditions. That is,
Environmental condition detection device 4 from instructor desk 3 to computer 2
Not to use (to pass the NO side in FIG. 4)
If conditions such as summer and winter are notified, the software of the computer 2 (specifically, the part that realizes the condition determiner 34) causes the dynamic characteristic model 36 to set the environmental condition setting data 31.
The data of the notified conditions are given. The environmental condition setting data 31 includes general environmental conditions in the summer in the controlled object, general environmental conditions in the winter, and the like.

[0005]

Since the conventional simulator for driving training is constructed as described above, this apparatus is used to carry out training from the same state as the plant state including the environmental state during actual driving. When performing, environmental data necessary to create environmental conditions, such as outside air temperature, humidity, cooling water temperature, operating conditions of other power plants outside the training range, and power demand, which are determined not by the operation result of the operator but by the natural environment. The voltage, frequency, etc. of the power system determined by external factors such as fluctuations in the same as the actual operating state in the prior art, but plant data other than environmental data, such as boilers, turbines, generators that change due to operator operation , Auxiliary equipment such as pumps and fans installed in each system, open / close status of switchgear such as circuit breakers and disconnectors, open / close status of valves, valve opening, and operation results. Pressure, flow rate, temperature, etc. of the boiler, turbine, generator body and each piping system, for example, bearing metal temperature of each equipment body, water supply, fuel, air, steam, exhaust gas, etc. There is a problem that it is necessary to simulate the simulation model based on the existing initial value data to make it the same data as the actual plant state during operation, and it is not possible to make it the same state as the actual plant in a short time.

The present invention has been made to solve the above problems, and an object thereof is to obtain an operation training simulator capable of starting training from a plant state during actual operation in a short time.
