Detailed Description
In order to solve the problems that the operation steps of heat engine operation of a power generation enterprise are complicated, the efficiency is low, the states of valves in power plant equipment cannot be synchronized in real time, and the safety is low in the prior art, the embodiment of the invention provides a monitoring method of a power plant valve and a monitoring device of the power plant valve.
The background art of the present invention is first described below:
before a power generation enterprise runs, initialization operation needs to be performed on the whole power generation system of the power generation enterprise, when the system initially starts to run, the valve state of the power generation system recorded in a computer is inconsistent with the valve state of a site, so the valve state of the power generation system recorded in the computer needs to be kept consistent with the valve state of the site through the initialization operation, and due to special requirements of isolation, signal sampling and the like, in the power generation enterprise, more than 70% of power plant equipment adopts a manual valve and cannot remotely acquire the valve state, so in the prior art, power plant personnel often acquire the state of the manual valve of the site by comparing the valve state of the site with the valve state recorded in the computer one by one, and time and labor are wasted. The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.

"and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" generally indicates that the preceding and following related objects are in an "or" relationship, unless otherwise specified. In addition, it should be understood that the terms first, second, etc. in the description of the embodiments of the invention are used for distinguishing between the descriptions and are not intended to indicate or imply relative importance or order to be construed.
Referring to fig. 1, an embodiment of the present invention provides a method for monitoring a valve of a power plant, which is applied to a control system of a power plant generator set, where the method for monitoring includes:
s10) obtaining a basic valve state list of the valves in the generator set;
s20) obtaining the current adjustment operation of the power plant personnel, and generating a corresponding typical operation list based on the adjustment operation;
s30) generating a screening operation list based on the basic valve state list and the typical operation list;
s40) obtaining an operation instruction of a user, and updating the basic valve state list based on the operation instruction and the screening operation list to obtain an updated basic valve state list.
In an embodiment of the present invention, the obtaining a basic valve state list of valves in the generator set includes: judging whether the updated basic valve state list exists or not; under the condition that the updated basic valve state list does not exist, acquiring a new valve state list, and taking the new valve state list as the basic valve state list; in the presence of the updated base valve state list, taking the updated base valve state list as the base valve state list.
In one possible embodiment, before the generator is operated once, the plant personnel cannot know the valve status of each valve because there is no basic valve status list, and therefore the plant personnel need to initialize the valve status of the plant equipment. In the process of carrying out initialization operation, power plant personnel firstly derive a typical heat engine operation ticket through a computer, and carry out large-scale operation once to power plant equipment according to the typical heat engine operation ticket, for example, carry out unit start operation to power plant equipment, after all operations are accomplished, power plant personnel lead in the typical heat engine operation ticket into the computer, power plant personnel only need compare remaining valve, just can accomplish remaining valve state initialization operation fast, thereby in the time of normal start-up, the basic operating mode of power plant equipment has been established more fast, and work efficiency is improved. After the verification and validation is complete, the plant personnel import the valve status in the typical heat engine operating ticket into the computer and save it as a base valve status list.
In another possible embodiment, the computer automatically uses the updated base valve status list as a new base valve status list before the next operation is performed, as the current base valve status list is updated by the plant personnel via the computer after the previous operation to generate the updated base valve status list.
In the embodiment of the invention, the basic valve state list is immediately updated in real time after each operation, so that the state of the power plant equipment valve stored in the computer is ensured to be consistent with the state of the on-site valve before each operation, and particularly for the manual valve which cannot be remotely monitored.
In an embodiment of the present invention, the generating a screening operation list based on the basic valve state list and the typical operation list includes: comparing the basic valve state list with the typical operation list, judging whether the operation valve state of the operation valve corresponding to each operation step in the typical operation list is the same as the basic valve state corresponding to the operation valve in the basic valve state list, and processing the typical operation list based on the judgment result: in the case that the operating valve state is the same as the basic valve state, deleting the operating step corresponding to the operating valve in the typical operation list; in the case that the operating valve state is not the same as the basic valve state, reserving an operating step corresponding to the operating valve in the typical operation list; and taking the processed typical operation list as the screening operation list.
In one possible implementation, the computer obtains the next operation content that needs to be performed by the plant personnel, and automatically generates a typical operation list according to the operation content, for example, A, B, C, D, E, F steps are included in the typical operation list, where a step represents opening the a valve, B step represents closing the B valve, C step represents opening the C valve, D step represents opening the D valve, E step represents closing the E valve, and F step represents opening the F valve, and the computer automatically compares the typical operation list with the basic valve state list, and finds that in the typical operation list, the corresponding valve in the step B, D, E is already consistent with the state of the B, D, E valve in the basic valve state list, so the computer automatically compares B, D, B, D, E, in the typical operation list, E three steps are eliminated and the corresponding valve states in the other three steps are inconsistent with those in the base valve state list, thus leaving the remaining three steps and generating a screening operation list that includes only A, C, F steps.
Because the states of the valves in all the power plant equipment cannot be obtained through remote monitoring before each operation in the prior art, after a heat engine operation ticket is exported from a computer each time, power plant personnel need to go to the site according to the heat engine operation ticket or manually execute and confirm each operation step on the computer, especially when a certain operation ticket has hundreds of operation steps and only a few valves need to be operated, a great deal of human resources are wasted, and extra operation risks are brought, so that by implementing the embodiment of the invention, the states of the valves of the power plant equipment can be updated in real time after each operation, the valves of the power plant equipment before each operation are ensured to be consistent with the states of the valves recorded on the computer, and each operation in the heat engine operation ticket exported each time has enough safety, the safety of power plant's work in has been guaranteed, furtherly, carries out optimization treatment through the heat engine operation ticket to exporting at every turn, can remove a large amount of invalid operations, and the operating procedure that has significantly reduced has promoted power plant personnel's work efficiency, and still greatly reduced simultaneously has further promoted the security of power plant's work because of the artificial operation risk that a large amount of operations brought.
In the embodiment of the present invention, the monitoring method further includes: acquiring an operation sequence number of each operation step in the screening operation list in the typical operation list; when a certain operation step does not comprise an operation serial number or is the same as the operation serial number of the previous operation step, setting the operation step and the previous operation step as the same operation serial number; when the operation serial number of a certain operation step is different from that of the previous operation step, the operation serial number of the operation step and the operation serial number of the previous operation step are sequentially set.
In the typical heat engine operation order, the valves closest to the power plant equipment can be preferentially operated, operation according to the sequence of the valves on the typical heat engine operation order is not needed, the work content of the power plant personnel can be further optimized, and the work efficiency of the power plant personnel is improved.
In this embodiment of the present invention, the obtaining an operation instruction of a user, and updating the basic valve state list based on the operation instruction and the screening operation list to obtain an updated basic valve state list includes: acquiring an input instruction of a user; inputting the screening operation list into the control system based on the input instruction; updating the base valve state list based on the screening operation list to obtain an updated base valve state list.
In the embodiment of the invention, after the power plant personnel perform the operation in the screening operation list each time, the current basic valve state list is immediately updated on the computer, so that the real-time monitoring of the valve of the power plant equipment by the computer is realized, the consistency between the valve state in the power plant equipment and the state displayed on the computer in real time is ensured, the accuracy of the valve state of the power plant equipment managed or monitored in the subsequent operation process is ensured, the accuracy of a typical heat engine operation ticket generated for the next operation is ensured, the operation safety of a power generation enterprise is ensured, and the work safety of the power plant personnel is improved.
