Description

Technical Field

[0001] The invention belongs to the field of testing technology, and in particular relates to a control instruction channel performance test method. Background Art

[0002] The DC shutdown circuit breaker panel is a safety-level device of the reactor protection system. Its main function is to control the power supply of the rod drive mechanism power system (RRS) and the rod control system (RPC), as well as to cut off or connect the circuit between the reactor and the power system. The main function of the shutdown circuit breaker is to cut off the connection between the reactor and the power system when shutdown is required to ensure the control and safety of the reactor. It can prevent the current of the power system from entering the reactor and disconnect the circuit to put the reactor in a shutdown state. Similarly, when restarting the reactor, the shutdown circuit breaker can connect the reactor and the power system to restore power supply. Therefore, it is necessary to ensure the functionality, accuracy and stability of the control command channel.

[0003] However, at present, when testing the performance of the control command channel corresponding to the shutdown circuit breaker panel, it is usually judged by conventional means of judging the delay rate and packet loss rate, and the state conversion, tripping and closing of the shutdown circuit breaker itself are not tested, resulting in low accuracy of the test results;

[0004] To this end, we propose a control instruction channel performance test method. Summary of the invention

[0021] Step S22, the shutdown circuit breaker receives the output control instruction generated by the instruction generation terminal and records the receiving time, and obtains the transmission time CSS of the corresponding output control instruction by subtracting the sending time from the receiving time;

[0022] Step S23, if the transmission duration is greater than or equal to the corresponding maximum standard response duration, an abnormal signal is generated, and the corresponding output control instruction is deemed invalid;

[0023] Step S24, if the transmission time is less than the corresponding maximum response time, the shutdown circuit breaker is adjusted to the corresponding state information according to the output control instruction, and recorded as the real-time state information, the real-time state information specifically includes the connection state, the test state and the disconnection state;

[0027] SKZ=e×λ / CSS, where e is a natural constant.

[0028] Furthermore, the output control instructions specifically include connection instructions, test instructions and disconnection instructions; successful matching specifically means that the connection instruction corresponds to the connection state, the test instruction corresponds to the test state, and the disconnection instruction corresponds to the disconnection state.

[0029] Furthermore, the step S3 also includes the following sub-steps:

[0030] Step S31, obtaining a control circuit diagram corresponding to the shutdown circuit breaker, wherein the control circuit diagram includes lead wires of the positive and negative control power supply busbars and contacts on the corresponding lead wires, switch KG and contacts 1 to 12 in switch KG, a make contact DH, a break contact DD, a red light RD, and a green light GN;

[0035] Furthermore, the step S32 further includes the following sub-steps:

[0036] Step S321, perform a manual closing test, adjust the switch KG to close the shutdown circuit breaker, at this time, the switch KG is in the "after closing" position, and the contacts 3-4 and 11-12 are connected;

[0037] Since the shutdown circuit breaker is in the closed state, the make contact DH is closed and the break contact DD is open, so only 11-12 is energized, and the current path is (+) → KG 11-12 →RD→DH→(-), so the red light emits a flat light;

[0038] Step S322, perform an automatic closing test, close the shutdown circuit breaker, at this time, the switch KG is in the "after closing" position, and the corresponding contacts 1-2 and contacts 7-8 of the switch KG are connected;

[0039] Since the shutdown circuit breaker is in the closed state, the make contact DH is closed and the break contact DD is open, so only contacts 7-8 are energized, and the current path is M100 (+) → KG 7-8 →RD→DH→(-), the red light is connected to the flash bus bar, so the red light flashes.

[0040] Furthermore, the step S33 also includes the following sub-steps:

[0041] Step S331, perform a manual trip test, adjust the switch KG to trip the shutdown circuit breaker, at this time, the switch KG is in the "after trip" position, and the electric shocks 1-2 and 7-8 are connected;

[0042] Since the shutdown circuit breaker is in the tripped state, the make contact DH is open and the break contact DD is closed, so only 1-2 is energized, and the current path is (+) → KG 1-2 →GN→DD→(-), so the green light emits a flat light;

[0043] Step S332, perform an automatic trip test, the shutdown circuit breaker trips, at this time, the switch KG is in the "post-trip position", and the corresponding contacts 3-4 and 11-12 of the switch KG are connected;

[0044] Since the break contact DD is closed and the make contact DH is open, only contact 3-4 is energized. At this time, the current path is M100 (+) → KG3-4 →GN→DD→(-), the green light is connected to the flash busbar M100(+), so the green light flashes.

[0045] Furthermore, the step S4 further includes the following sub-steps:

[0046] Step S41, calculating the control excellence level value KYD of the corresponding shutdown circuit breaker by a formula, the specific formula is as follows:

[0047] KYD=SKZ×BZ; where BZ is the gate position correction coefficient of the shutdown circuit breaker at different gate position levels. The gate position correction coefficient BZ of the shutdown circuit breaker corresponding to the first gate position is a1, the gate position correction coefficient BZ of the second gate position is a2, and the gate position correction coefficient BZ of the shutdown circuit breaker corresponding to the third gate position is a3, 0<a3<a2<a1;

[0048] Step S42, comparing the control excellence level value of the shutdown circuit breaker with the excellence threshold;

[0049] Step S43, if the control excellence level value of the shutdown circuit breaker is greater than or equal to the first excellence threshold, the control excellence level of the shutdown circuit breaker is recorded as first-level control;

[0050] Step S44, if the control excellence level of the shutdown circuit breaker is less than the first excellence threshold and greater than or equal to the second excellence threshold, the control excellence level of the shutdown circuit breaker is recorded as level 2 control;

[0051] In step S45, if the control excellence level value of the shutdown circuit breaker is less than the second excellence threshold, the control excellence level of the corresponding shutdown circuit breaker is recorded as level three control.

[0052] Furthermore, the first excellent threshold is greater than the second excellent threshold, the command channel performance of the first-level control corresponding to the shutdown circuit breaker is better than the command channel performance of the second-level control corresponding to the shutdown circuit breaker, and the command channel performance of the second-level control corresponding to the shutdown circuit breaker is better than the command channel performance of the third-level control corresponding to the shutdown circuit breaker.

[0053] Furthermore, the step S5 further includes the following sub-steps:

[0054] For the shutdown circuit breaker corresponding to the abnormal signal, replace it with a confirmed shutdown circuit breaker. For the shutdown circuit breaker corresponding to the third-level control, check the electrical connection and contact damage. For the shutdown circuit breaker corresponding to the second-level control and the first-level control, do not perform any operation.

[0055] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0056] The present invention first obtains the real-time voltage value of each shutdown circuit breaker corresponding to the shutdown circuit breaker panel, and makes an initial judgment on the shutdown circuit breaker, then performs an output control instruction test on the shutdown circuit breaker, and obtains the output control level value corresponding to the shutdown circuit breaker, then performs a closing test and a tripping test on the shutdown circuit breaker, and obtains the gate position level corresponding to the shutdown circuit breaker, and finally obtains the control excellence level corresponding to the shutdown circuit breaker by comprehensively evaluating the channel performance of the shutdown circuit breaker, and the user terminal receives the abnormal signal or the control excellence level corresponding to the shutdown circuit breaker, and learns the state of the corresponding shutdown circuit breaker according to the abnormal signal or the control excellence level and makes a response, so as to accurately judge the control instruction channel performance corresponding to the shutdown circuit breaker panel.

[0062] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] Embodiment 1:

[0064] See also Figure 1-Figure 3 As shown, the technical solution provided by the present invention is: a control instruction channel performance test method, comprising:

[0065] It should be noted in advance that the DC shutdown circuit breaker panel described in this embodiment belongs to the safety-level equipment of the reactor protection system. The DC shutdown circuit breaker panel is connected to eight shutdown circuit breakers. The main contacts of the eight shutdown circuit breakers are connected to form a four-out-of-two logic and are connected in series in the power supply circuit. Figure 2As shown, the shutdown circuit breakers are controlled by four sequence protection groups respectively, each sequence protection group controls two shutdown circuit breakers, and only one shutdown circuit breaker is tested each time. Since the shutdown circuit breaker adopts a four-out-of-two logic setting, the operation of the reactor will not be affected when the control instruction test is performed; in this embodiment, the terminal for generating an output control instruction is defined as an instruction generation terminal;

[0068] Step S11, if the number of real-time voltage values ​​of the shutdown circuit breaker is less than eight, an abnormal signal is generated; if the number of corresponding status information of the shutdown circuit breaker is equal to eight, the next step is entered;

[0069] Step S12, obtaining a standard undervoltage voltage value of the undervoltage release corresponding to the shutdown circuit breaker and a standard shunt voltage value of the shunt release;

[0070] Among them, the undervoltage release is used to provide undervoltage protection for the shutdown circuit breaker. When the voltage in the circuit where the shutdown circuit breaker is located is too low, it automatically trips and disconnects from the power supply; the shunt release is used to realize the disconnection operation of the remote circuit breaker. The electromagnetic coil of the shunt release is connected in series with a starting switch, and then connected in parallel with the circuit where the shutdown circuit breaker is located; the shunt release is set to prevent greater accident losses or protect certain facilities. For example, in case of a fire in a certain area, before the use of fire sprinklers or fire hydrants, in order to prevent electric shock, the shunt coil is driven by the fire signal to cut off the power supply circuit in this area to avoid secondary injuries caused by electric shock during the rescue process;

[0071] Step S13, comparing the real-time voltage value in the shutdown circuit breaker with the standard undervoltage voltage value of the undervoltage release and the standard shunt voltage value of the shunt release;

[0078] Step S22, the shutdown circuit breaker receives the output control instruction generated by the instruction generation terminal and records the receiving time, and obtains the transmission time CSS of the corresponding output control instruction by subtracting the sending time from the receiving time;

[0079] Step S23, if the transmission duration is greater than or equal to the corresponding maximum standard response duration, an abnormal signal is generated, and the corresponding output control instruction is deemed invalid;

[0080] Step S24, if the transmission time is less than the corresponding maximum response time, the shutdown circuit breaker is adjusted to the corresponding state information according to the output control instruction, and recorded as the real-time state information, the real-time state information specifically includes the connection state, the test state and the disconnection state;

[0081] Step S25, acquiring real-time status information, and matching the real-time status information with the corresponding output control instruction. If the match is unsuccessful, an abnormal signal is generated and sent to the user terminal;

[0082] Step S26, if only one output control instruction is successfully matched, an abnormal signal is generated and sent to the user terminal; if two output control instructions are successfully matched, the value of the output control coefficient λ corresponding to the shutdown circuit breaker is set to X2; if all three output control instructions are successfully matched, the value of the output control coefficient λ corresponding to the shutdown circuit breaker is set to X1, where 0<X2<X1;
