the invention relates to an automatic inspection method applied to a triple redundancy overspeed protection device.
Background art:
the steam turbine generator unit is a machine rotating at a high speed, and the rated rotating speed is generally 3000 r/min. Once excessive speed occurs, significant property damage and personal injury can occur. The triple redundant overspeed protection device is used as a core part of a turbine overspeed protection system, and is required to be periodically subjected to inspection testing due to the important responsibility of speed monitoring and trip signal output to inhibit the damage of turbine overspeed accidents. The existing manual inspection method is complex in operation, easy to mistake, time-consuming and labor-consuming, and limited in test items and test precision; the existing automatic inspection method needs to additionally install a test module, test items are difficult to completely cover a triple redundant framework device, the test time is long, great interference is caused on speed monitoring and overspeed trip functions, speed measurement deviation and error trip are easily caused, and long-term stable operation of the device on site is not facilitated.
The invention content is as follows:
the invention aims to overcome the technical defects of the conventional automatic inspection method and provide an automatic inspection method applied to a triple redundancy overspeed protection device.
The technical scheme adopted by the invention is as follows: the automatic inspection method applied to the triple redundancy overspeed protection device comprises the triple redundancy overspeed protection device used for collecting and processing three paths of rotating speed signals of the same rotating machine, wherein the triple redundancy overspeed protection device comprises three mutually redundant overspeed protection modules and a two-out-of-three voting module, the three overspeed protection modules correspondingly output three paths of mutually independent voting trip signals, and when the two paths or three paths of voting trip signals are simultaneously output to the two-out-of-three voting module, the overspeed protection device performs trip actions, and the automatic inspection method is characterized in that: the automatic inspection method comprises the following steps:
1) each of the three overspeed protection modules comprises an inspection control module, the two-out-of-three voting module comprises an inspection logic loop, and the inspection test of each overspeed protection module is controlled and supervised by the inspection control module; the system defines one of the three inspection control modules as an inspection master controller, the remaining two inspection control modules are defined as inspection slave controllers, the inspection master controller sets an inspection timing period, the inspection control modules monitor the running states of the three overspeed protection modules through a detection inspection logic loop after each inspection timing period is reached, and if the three inspection control modules respectively judge that the three overspeed protection modules are in the running states, the inspection master controller initiates an automatic inspection test flow of the whole overspeed protection device;
2) after the automatic inspection process is started, each overspeed protection module uninterruptedly feeds back the running state of the overspeed protection module to the inspection logic circuit, each overspeed protection module can uninterruptedly read the running states of other overspeed protection modules from the inspection logic circuit, if the inspection master controller monitors that other overspeed protection modules are in abnormal running states, the inspection master controller immediately stops the inspection test activity of the module or prohibits the inspection test activity of the module from starting, and stops sending inspection test starting commands to other inspection slave controllers; if the inspection slave controller monitors that other overspeed protection modules are in abnormal operation states, the inspection test activity of the module is immediately stopped or the inspection test activity of the module is prohibited to be started;
3) the feedback of the operating state of the overspeed protection module is realized by different level differentiation of each overspeed protection module: when the overspeed protection module normally executes the monitoring protection task of the rotating speed of the steam turbine, one path of heartbeat level is continuously output to the inspection logic circuit, and the overspeed protection module is in an online state; when the overspeed protection module is in an abnormal operation state, one path of high level is continuously output to the inspection logic circuit to indicate an off-line state;
4) the single overspeed protection module monitors the running states of the other two redundant overspeed protection modules, and is realized by reading the level states of the other two redundant overspeed protection modules from the inspection logic circuit, and when the level fed back to the inspection logic circuit by the remaining one of the overspeed protection modules is a heartbeat level or a high level, the monitored overspeed protection module is in an online state or an offline state.

The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the invention relates to an automatic inspection method applied to a triple redundancy overspeed protection device, a structural framework of the triple redundancy overspeed protection device supported by the automatic inspection method is shown in fig. 1, and in terms of a hardware structure, the triple redundancy protection device consists of three mutually redundant overspeed protection modules and a two-out-of-three voting module. The three overspeed protection modules are independent from each other in the aspect of overspeed protection trip output function, and each overspeed protection module can independently output a trip signal for voting. Three-way voting trip signals from the overspeed protection module are converged into a two-out-of-three voting module, and one final trip signal is output through a two-out-of-three voting loop.
Based on a three-out-of-two-trip voting strategy of the overspeed protection device, only two or three trips output trip signals simultaneously, and the final trip signal output and trip action are caused. Therefore, under the normal condition that no trip signal is output in three paths, the condition that one path of trip signal is output is artificially manufactured in a short time due to the requirement of testing. The method is a basic premise for realizing the full-loop test from the input of a rotating speed signal to the output of a trip signal and the action of the trip in the test process of a single overspeed protection module.
The automatic inspection method of the invention is to manufacture three overspeed protection modules in a time-sharing way under the condition of overspeed protection device trip-out so as to verify the validity of the speed measurement protection function of each overspeed protection module.
The overspeed protection module consists of an inspection control module, a speed monitoring module and a trip execution module; the two-out-of-three voting module consists of a two-out-of-three voting loop and an inspection logic loop. Each module or circuit is composed of respective software and hardware to realize corresponding functions.
The automatic inspection method applied to the triple redundant overspeed protection device comprises a single module automatic inspection flow and a whole device automatic inspection flow. The automatic inspection flow of the single module is responsible for guiding the automatic inspection activity in the single module, the whole test loop is positioned in the single overspeed protection module and consists of an inspection control module, a speed monitoring module and a trip execution module, and the structure is shown in figure 2.
The automatic inspection process of the single module is shown in fig. 3, and mainly comprises test items of a speed detection function test and a trip execution function test, which are used for verifying whether the single module has complete speed measurement and trip safety protection functions. The test is controlled and supervised by the inspection control module, and if any phenomenon which is inconsistent with the expectation occurs in the process, the module is directly judged to automatically inspect and fail.
The automatic inspection of the whole device is responsible for scheduling the automatic inspection activity of the whole device, is used for forming the core part of an inspection test loop, and is respectively an inspection logic loop in a two-out-of-three voting module and an inspection control module in three overspeed protection modules, and the structure of the inspection logic loop is shown in figure 4.
In the automatic routing inspection method, the operation state of the overspeed protection module is defined as "on-line" and "off-line". "on-line" means the state in which the module is normally performing the turbine speed monitoring protection task; "off-line" means that the module is not performing all abnormal operating conditions of the turbine speed monitoring protection task normally, as may be the case: failure of the module, damage to the module, removal of the module, ongoing inspection of the module, failure during inspection of the module, etc.
Each overspeed protection module can actively feed back the real-time operation state of the module to the inspection logic loop, so that other modules can monitor the state of the module in the automatic inspection process of the whole device. The operation state feedback is realized by different level differentiation. When the module is in the state of normally executing the monitoring protection task of the rotating speed of the steam turbine, one path of heartbeat level is continuously output to the inspection logic circuit, and the online state is indicated; when the module is in an abnormal operation state, a high level is continuously output to the inspection logic loop, and the offline state is indicated. Such as: when the module starts to inspect, one path of high level is actively and continuously output to the inspection logic loop, and the offline state is indicated; when the module finishes the inspection, the module actively and continuously outputs a heartbeat level to the inspection logic loop to indicate the online state, as shown in fig. 5.
According to the two-out-of-three voting logic, when more than one overspeed protection module is in an off-line state, the whole device directly outputs a trip signal and executes a trip action. The whole device must strictly avoid the situation that the automatic inspection test directly causes/participates in causing the trip.
The core technical point of the automatic inspection method of the whole device is that whether the whole device/single module has the automatic inspection starting condition is monitored in real time so as to minimize the influence of the test activity on the system safety. The method strictly ensures that automatic inspection test is allowed to be carried out on at most one overspeed protection module only when the three overspeed protection modules are in an online state; the method strictly avoids starting/allowing automatic inspection tests of other overspeed protection modules under the condition that the existing overspeed protection module is in an off-line state; the method strictly avoids more than one overspeed protection module from simultaneously carrying out automatic inspection tests.
In the aspect of implementation of the method, due to the dispatching requirement, the inspection control module in the three overspeed protection modules needs to be defined as an automatic inspection master module and an automatic inspection slave module in a distinguishing way. The two modules are identical in overspeed protection function, but differ in automatic routing inspection function. After the system is powered on, the three overspeed protection modules are respectively and automatically defined as a module A, a module B and a module C according to the difference of slot addresses. The modules a located in the slot a are defined as automatic patrol master modules, the patrol control modules are defined as patrol master controllers, and the modules B, C located in the slot B, C are all defined as automatic patrol slave modules, and the patrol control modules are defined as patrol slave controllers.
The inspection main controller is responsible for controlling and scheduling the automatic inspection process of the whole device, and the specific task comprises configuring all relevant parameters of automatic inspection; timing; actively initiating and stopping an automatic inspection process; actively carrying out inspection operation on the module; monitoring the running state of the automatic inspection slave module; sending an inspection starting command to the automatic inspection slave module; and feeding back a polling result.
The inspection slave controller is responsible for receiving an inspection starting command from the automatic inspection master module and then performing inspection operation on the module; monitoring the operating state of other modules; and feeding back the running state or the inspection result of the module.
The automatic inspection method of the present invention is described in detail with reference to fig. 6:
1) after the periodic automatic polling function is enabled, the polling main controller performs timing. When the timing time is up, the inspection main controller monitors the running states of the module A, the module B and the module C by detecting the inspection logic loop. If three stable heartbeat levels are detected, the module A, B, C is in an online state, and the whole device is judged to have automatic polling starting conditions. The state of the levels that can be monitored as feedback from each module in the patrol logic loop is shown in fig. 7. The inspection main controller actively starts the automatic inspection flow of the whole device.
2) After the automatic inspection flow of the whole device is started, the single module of the module A is automatically inspected firstly. The single module automatic routing inspection process is as described in the previous section, all routing inspection operations are performed in the overspeed protection module. In the process of implementing single module automatic inspection by the module A, the inspection main controller can continuously monitor whether the states of the module B and the module C in the inspection logic loop are kept on line. The state of the level fed back by each module in the patrol logic loop can be monitored at this time as shown in fig. 8.
3) When the single module of the module A is automatically inspected and tested and the test is passed, the inspection main controller can continuously monitor the operation states of the module A, the module B and the module C through the inspection logic loop. If three stable "heartbeat" levels are detected, the module A, B, C is in the "online" state, and at this time, the module B "has the automatic polling start condition", and at this time, the level state fed back by each module in the polling logic circuit can be monitored as shown in fig. 9. And the inspection main controller sends a single-module automatic inspection starting command to the inspection control module of the module B through the inspection logic circuit. After receiving the single module automatic inspection command, the module B monitors the running states of the module A, the module B and the module C through an inspection logic circuit. If three stable heartbeat levels are detected, the module A, B, C is in an online state, and at the moment, the module B determines that the module has an automatic inspection starting condition, and the inspection control module starts the automatic inspection of the module B.
4) Single module automated routing inspection of module B was performed. The single module automatic routing inspection process is as described in the previous section, all routing inspection operations are performed in the overspeed protection module. When the single module of the module B is automatically inspected and tested to be finished and the test is passed, the inspection main controller can continuously monitor the operation states of the module A, the module B and the module C through the inspection logic loop. If three stable heartbeat levels are detected, the module A, B, C is in an online state, and the module C is determined to have an automatic polling starting condition. And the inspection main controller sends a single-module automatic inspection starting command to the inspection control module of the module C through the inspection logic circuit. After receiving the single module automatic inspection command, the module C monitors the running states of the module A, the module B and the module C through an inspection logic circuit. If three stable heartbeat levels are detected, the module A, B, C is in an online state, and at the moment, the module is determined to have an automatic inspection starting condition, and the inspection control module of the module C starts automatic inspection of the module.
5) Single module automated routing inspection of module C was performed. The single module automatic routing inspection process is as described in the previous section, all routing inspection operations are performed in the overspeed protection module. When the single module of the module C is automatically inspected and tested and the test is passed, the inspection main controller can continuously monitor the operation states of the module A, the module B and the module C through the inspection logic loop. If three stable heartbeat levels are detected, the module A, B, C is in an online state, and the automatic inspection of the whole device is determined to be finished.
6) And the inspection main controller finishes the automatic inspection flow of the round device, implements information feedback according to the detection result, starts the automatic inspection cycle timing, and waits for starting the automatic inspection flow of the next round device.
7) If all overspeed protection modules pass the test, and no flow, phenomenon or conclusion which is inconsistent with the expectation exists in the automatic inspection flow of the whole device, the automatic inspection is judged to be normal. And judging the other conditions as abnormal conditions.
The automatic routing inspection exceptions are subdivided into result exceptions and flow exceptions. In the process of polling any overspeed protection module, once the module monitors that a detection item of the module does not pass, the module immediately stops the current polling activity, judges that the result is abnormal, informs a polling main controller, disables the automatic polling function, suspends polling period timing, feeds back fault information to a user and waits for subsequent processing; when any module is in the process of inspection, once the module monitors that other modules are in an off-line state or detects that any link is overtime, advanced, stagnated and repeated, the current inspection activity is immediately stopped, the module is judged to be abnormal in flow and informs an inspection main controller, the automatic inspection function is disabled, the inspection cycle timing is suspended, fault information is fed back to a user, and the follow-up processing is waited.
Whether each overspeed protection module is in normal monitoring protection or automatic inspection test, the operation states of other two overspeed protection modules are monitored continuously in real time. If the condition of off-line of other modules is monitored, the module is determined to have no automatic inspection starting condition or the current automatic inspection test activity of the module is directly stopped.
If the inspection main controller monitors that any module running state feedback which is not in accordance with the expectation or receives any abnormal notification, the inspection main controller immediately disables the automatic inspection function, suspends the inspection cycle timing, feeds back fault information to a user and waits for manual processing.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
