The present invention relates to a system for simulating a control board attached to a control element drive mechanism control system (hereinafter referred to as 'CEDMCS'), and more specifically, the overall abnormal situation of each control board. It is possible to induce each control board more reasonably without any unnecessary cost and manpower waste on the nuclear power plant side by inducing the failure and troubles to be precisely pre-checked and diagnosed / tracked without complicated procedures such as directly operating the CEDMCS. The present invention relates to a simulation system of CEDMCS-attached control boards that can be guided to ensure stable operation and management.

Normally, under the conventional system, as shown in FIG. 1, the control rod drive device 4 disposed in the nuclear power plant drives the control rod 5 electrically / mechanically in accordance with a control signal output from the CEDMCS 2 side. Control rod 5 arranged inside the reactor to normally perform the functions given to it (e.g., inserting or withdrawing into the reactor core to control nuclear reactivity or free-falling to stop the reactor). It will play a role.

In this case, the CEDMCS 2 appropriately controls the control rod drive device 4 according to the power output from the power and control signal supply tool 1 side and the control signal (including the control signal output from the other system 3 side). By performing the control in such a manner, the overall control of the control rod drive device 4, for example, the withdrawal and insertion procedures of the control rod 5, the starting procedure of the reactor, the stopping procedure of the reactor, etc., may be performed. .

Under such a conventional system, as shown in the drawing, the CEDMCS 2 includes, for example, a control rod drive signal combination board, a voltage application time control board, a pulse signal generation board, a logic signal providing board, and a zero potential detection signal generation board. A plurality of accessory control boards 10, such as a drive signal transfer board and a drive current output board, are systematically arranged.

Of course, these control boards 10 perform very important signal processing roles which are directly related to the functions of the control rod drive device 4 and the control rod 5, in a systemic relationship with each other. In (10), when an abnormal condition is caused, and the abnormal condition is left without prompt action, the aftermath becomes bound to the malfunction of the control rod drive device 4 and the control rod 5 directly, and eventually, The functional impairment of the control rod drive device 4 and the control rod 5 will lead to an irreversible power plant accident.

In view of the significance of such a problem, the conventional nuclear power plant side checks the abnormal state of the control board from time to time by, for example, removing a coating of each control board 10 and contacting a test probe. , Through this, in order to block the failure of the control board 10 in advance, devotes a lot of effort and time.

However, since the conventional control boards 10 are not individually separated from each other but operate systematically under the systematic linkage with other control boards 10, each control board 10 Simple measures, such as connecting a test transducer to the power supply system, cannot precisely check and diagnose the entire abnormal situation and cause of failure of each control board 10 (i.e., under the conventional system, each control board is connected to CEDMCS). There is no way to determine the abnormal state of the control board as a whole without taking a rather reckless method of installation and driving.) After all, even though the nuclear power plant devotes a lot of effort and time, the control board I have no choice but to face the difficult situation that I cannot cope with the failure situation of (10) more appropriately The.

Of course, when the failure of the control board 10 is actually caused in the situation of not grasping such an abnormal situation, the nuclear power plant side burdens such as replacing each control board 10 or reconnecting the connector to prevent an accident. Unavoidable measures will be inevitably taken, and as a result, there will be no choice but to bear various problems such as waste of manpower and waste of money.

Accordingly, an object of the present invention is to provide a computer module, simulation (simulation drive) that can systematically simulate (control drive) the control boards attached to (or to be attached to) the CEDMCS under the same environment as the actual signal linkage of the power plant. The execution status of each control board (eg, mounting status of the control boards, signal flow status between the control boards, data input / output status of the control boards, temperature status of the power device, etc.) is collected and displayed in real time or at regular intervals. By systematically arranging computer modules that can record and diagnose, and through this, it is possible to precisely check and diagnose / track precisely without complicated procedures such as overall operation of each control board and cause of failure by directly operating CEDMCS. By encouraging them to be more efficient, on the nuclear power plant side, each control board is more reasonable, without unnecessary waste of labor and manpower. It is to induce stable operation and management.

Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In order to achieve the above object, the present invention provides a control board simulation execution set mounted on the control board and simulated under the same signal input / output environment as the actual power plant environment; And a control board diagnostic set electrically connected to the control board simulation execution set, and acquiring, recording, and analyzing a simulation execution state of the control board to diagnose and manage an abnormal state of the control board. The simulation set is equipped with the control board under the same signal input / output pattern as the actual power plant environment, and simulates the control board while collecting the simulation execution status of the control board and outputting the control board to the control board diagnosis set.

At this time, the control rod driving device simulation test set 700 is previously applied by the present applicant, registered invention (patent registration No. 560930) (name: control rod drive simulation test device for verification of control rod drive device control system of nuclear power plant) As described above, when the control boards 10 are mounted in the control board simulation execution set 300 and perform a series of simulation execution operations, the control rods form an electrical connection therewith. The drive simulation test set 700, according to its execution, proceeds appropriately with a procedure for electrically / mechanically driving one of the control rods 701, for example, and is eventually placed inside the simulation reactor. The control rod 701 may perform the functions given to it (eg, the function of inserting or withdrawing into the reactor core, controlling the nuclear reactivity, freefalling, stopping the reactor, etc.) as if in reality. It will lead you to a good simulation.

Of course, under the arrangement and operation of the control rod driving simulation set 700, each control board 10 mounted on the control board simulation execution set 300 is the same as the environment of the actual nuclear power plant, the control rod driving apparatus While driving the simulation test set 700, it is possible to more accurately diagnose / verify their abnormal state.

At this time, as shown in Figure 3, the control board simulation execution unit 400 is a control board mounting guide module 420, board status report module 430, the simulation verification signal processing module 440, etc. are closely combined It takes a configuration.

Here, the control board mounting guide module 420 is a board mounting terminal arranged in the same signal input / output pattern as the actual power plant environment, for example, control rod drive signal combination board mounting terminal 421, voltage application time control board mounting terminal ( 422), pulse signal generation board mounting terminal 423, logic signal providing board mounting terminal 424, logic filter mounting terminal 425, zero potential detection signal generation board mounting terminal 426, drive signal transmission board top re-terminal 427, a drive current output board mounting terminal 428, and the like, each control board, for example, control rod drive signal combination board 11, voltage application time control board 12, pulse signal generation board 13 The simulation power supply unit 500 provides flexible mounting areas such as a logic signal providing board 14, a zero potential detection signal generation board 15, a drive signal transmission board 16, a drive current output board 17, and the like. ) And control beam According to the simulation and power simulation control signal outputted from the simulation execution control unit 600 side, and performs a role of running in front of each of the control board 10.

After filtering and generating an accurate zero cross pulse signal, the procedure for transferring the generated zero potential detection signal to the pulse signal generation board 13 is simulated flexibly, as in an actual power plant. The drive signal transfer board 16 mounted in the drive signal transfer board mounting terminal 427 transfers a drive signal (logic signal) from the logic signal providing board 14 side to the drive current output board 17 side.

In this case, the current sensor S1 is arranged in the control rod drive simulation set 700, forming a structure disposed on the signal path between the drive current output board 17 and the control rod drive simulation set. When the counter electromotive force is induced by the movement of the control rod 701, and the current flowing through the coil of the control rod driving simulation set 700 is instantaneously reversed, the point is detected and the detection result is driven. By transmitting to the device simulation test set current state check unit 433 side, the control rod driving device simulated test set current state check unit 433 serves to assist the normal progress without any problem.

By detecting and transmitting the detection result to the control board temperature state checking unit 437, the temperature checking procedure performed by the control board temperature state checking unit 437 may be performed without any problem.

Meanwhile, as illustrated in FIG. 3, the simulation verification signal processing module 440 disposed in the control board simulation execution unit 400 together with each of the above-described modules may be used to control the control board mounting guide module 420. When the simulation verification signal is transmitted from the control board diagnosis set 200 side while taking a structure that is connected to the board mounting terminals 421 to 428, the simulation verification signal is transmitted to each board mounting terminal 421 to 428.
