Description

Technical Field

[0001] The invention relates to the technical field of water inlet ball valves, and in particular to a remote control optimization algorithm for water inlet ball valves. Background Art

[0002] As a supporting equipment for hydropower generation, the high-head and large-diameter intelligent controlled water inlet ball valve is the core part for cutting off the water source of the entire unit.

[0003] The invention patent with application number 201410845814.5 discloses a control method for a water turbine inlet ball valve, which is characterized in that: the method comprises the following steps: the water turbine inlet ball valve is opened by hydraulic drive and closed by relying on the potential energy of a heavy hammer, and its actions are valve opening, locking and valve closing, which are specifically described as follows: 1. The valve is opened by utilizing the force of the hydraulic control station and the lifting cylinder of the relay, through the rocker arm, the heavy hammer and the valve stem, driving the opening and closing member to rotate 90°. At the same time, the force of the hydraulic control station and the lifting cylinder also lifts the heavy hammer vertically through the rocker arm, converting the gravity of the heavy hammer into potential energy, so as to prepare the power for closing the valve. 2. The locking adopts manual mechanical locking or automatic mechanical locking; when manual mechanical locking is adopted, after the regulating valve is fully opened, the locking pin is directly put in or pulled out. At the same time, a manual locking input or pull-out signal indicating device is provided; when automatic mechanical locking is adopted, after the valve is fully opened, the mechanical locking shaft is first driven by the force of the transmission cylinder to be put into the locking position for initial locking, and then the electromagnetic force of the electromagnet drives the electromagnetic locking shaft for final locking. The locking process is fully automatic under the action of a series of travel switches. Under the condition that the electromagnet does not lose power, the electromagnetic locking shaft and the mechanical locking shaft can realize safety control.

[0004] The application is about the problem of "due to the special requirements of turbine operation, the general series ball valves cannot meet the use requirements of the working system during the operation of the hydropower station, resulting in the unit being unable to operate from time to time."

[0005] However, the control application of the water inlet ball valve mainly serves the daily operation of the turbine. When a turbine fails, the water inlet ball valve switches the water flow to provide a maintenance environment for the turbine. Although the water inlet ball valve currently has a remote control system, its autonomy is poor and it is unable to better cooperate with the turbine operating status to adaptively control the water flow and reduce the losses caused by turbine failures. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a remote control optimization algorithm for a water inlet ball valve, which solves the technical problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A water inlet ball valve remote control optimization algorithm, comprising: The distribution information of the turbine and the water inlet ball valve is obtained, and the distribution topology of the turbine and the water inlet ball valve is constructed based on the distribution information of the turbine and the water inlet ball valve, and the control direction of the water inlet ball valve is marked on the distribution topology of the turbine and the water inlet ball valve; a monitoring period is set, and the turbine operating status parameters are monitored in real time based on the monitoring period; a parameter screening logic is set, and the monitored turbine operating status parameters are screened by the parameter screening logic; the screened turbine operating status parameters are obtained in real time, and the turbine operating status safety situation is analyzed based on the obtained turbine operating status parameters; the turbine operating status safety situation analysis results are obtained, and whether the turbine operating status is safe is determined according to the analysis results; the water inlet ball valve control strategy is set, and when the determination result of whether the turbine operating status is safe is no, the water inlet ball valve control strategy is applied to control the operation of the water inlet ball valve.

[0008] Furthermore, when constructing the distribution information of the water turbine and the water inlet ball valve and the deployment position information of the water turbine and the water inlet ball valve, the distribution topology of the water turbine and the water inlet ball valve is constructed, all the distribution information of the water turbine and the water inlet ball valve is placed in the same coordinate system for representation, and all the distribution information of the water turbine and the water inlet ball valve in the coordinate system is continuously selected, and each time a group of water turbine or water inlet ball valve distribution information is selected, when the distribution information of the water turbine or the water inlet ball valve is selected in the coordinate system, the picking operation of the water turbine or water inlet ball valve distribution information associated with the selected water turbine or water inlet ball valve distribution information is further performed, so that the selected water turbine or water inlet ball valve distribution information is connected with the picked water turbine or water inlet ball valve distribution information to construct the construction of the distribution topology of the water turbine and the water inlet ball valve; Among them, after the turbine and water inlet ball valve distribution topology is constructed, the connection between the turbine and water inlet ball valve distribution information is the pipeline connecting the turbine and the water inlet ball valve. The water inlet ball valve control direction marked on the turbine and water inlet ball valve distribution topology is placed at the connection position between the turbine and water inlet ball valve distribution information. The water inlet ball valve control direction is the direction of water flow transmitted in the pipeline connecting the turbine and the water inlet ball valve.

[0009] Furthermore, the monitoring period is set to comply with: ; Where: is the monitoring period; is the initial default monitoring period; is the collection of turbines in the turbine and inlet ball valve distribution topology; is the total amount of the upper water inlet ball valves of the i-th group of turbines; is the judgment function; in, Table pair Averaging, decision function When j is the direct-controlled water inlet ball valve of the i-th group of turbines, the judgment function When the value of is 1 and j is the non-directly controlled water inlet ball valve of the i-th group of turbines, the judgment function The value of is 0, It is used to indicate the complexity of turbine and water inlet ball valve distribution based on the topology level of turbine and water inlet ball valve distribution.

[0010] Furthermore, the operating state parameters of the turbine are monitored in real time through a set monitoring period, and the monitoring period for monitoring the operating state parameters of the turbine is reset when the turbine and the water inlet ball valve are configured differently in the distribution topology of the turbine and the water inlet ball valve. The operating state parameters of the turbine are monitored by a water quality sensor and a torque sensor. The operating state parameters of the turbine include: turbidity and pH value of the water flow passing through the turbine, operating speed of the turbine, and operating power of the turbine; Among them, the torque sensor and the water quality sensor perform data interaction operations based on the local area network, so that the turbine operation status parameters monitored by all sensors are collected in any group of designated sensors while being marked with the location information of the parameter source sensors.

[0011] Furthermore, the parameter screening logic is expressed as: Logic1: Set several groups of turbine status safety judgment thresholds, which are respectively applied to the comparison of the turbidity and pH value of the water flow passing through the turbine, the turbine operating speed, and the turbine operating power; Logic2: Obtain any three consecutive sets of turbine operating status parameters monitored during the monitoring period, and compare the three consecutive sets of turbine operating status parameters with the corresponding turbine status safety judgment thresholds to determine whether the turbine is safe based on all turbine status safety judgment thresholds; Logic3: If the judgment result is yes, the turbine operating status parameters monitored in three consecutive monitoring cycles are discarded, otherwise, they are saved; Among them, when the three sets of turbine operating status parameters discarded in Logic3 are from the latest three sets of monitoring cycles, the turbine operating status is judged to be safe.

[0012] Furthermore, the analysis operation of the safety situation of the turbine operation status is performed once each time a new turbine operation status parameter is acquired; The source of the turbine operating status parameters used to analyze the safety situation of the turbine operating status is the sensor that collects all the turbine operating status parameters. In the turbine operating status safety situation analysis stage, the turbine operating status parameters based on the four groups with the latest time series are always used among the obtained filtered and processed turbine operating status parameters.

[0013] Furthermore, the analysis logic of the safety situation of the turbine operation state is expressed as:

[0014] Where: is the safety situation value of the turbine operation status; is the turbine operating speed in the vth group of turbine operating state parameters; is the turbine operating power in the vth group of turbine operating state parameters; is the pH value of the water flowing through the turbine in the vth group of turbine operating state parameters; , is the weight; is the turbidity of the water flow passing through the turbine in the vth group of turbine operating state parameters; Among them, the latest four groups of turbine operating state parameters are recorded based on the above calculation results as The larger the safety situation value of the turbine operation status is, the safer the turbine operation status is, and vice versa.

[0015] Furthermore, the decision logic of whether the turbine operation state is safe is expressed as: In the above formula, if either or both of formula (1) and formula (2) are true, it means that the turbine is in a safe operating state; if neither of formula (1) and formula (2) is true, it means that the turbine is in an unsafe operating state.

[0016] Furthermore, the water inlet ball valve control strategy includes: Control the closing of the water inlet ball valve: the water inlet ball valve in the pipeline with a larger diameter is closed first, the water inlet ball valve close to the turbine determined to be in an unsafe operating state is closed first, and the water inlet ball valve in a higher position relative to the turbine determined to be in an unsafe operating state is closed first; The closing control of the water inlet ball valve is remotely controlled based on a wireless network.

[0017] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects: The present invention provides an inlet ball valve remote control optimization algorithm. During the execution of the algorithm, the superior-subordinate relationship between the inlet ball valve and the turbine is identified by constructing a distribution topology of the turbine and the inlet ball valve. The operating state safety of the turbine is further determined by monitoring and analyzing the operating state parameters of the turbine. Based on the determination result, the inlet ball valve is remotely and intelligently controlled to ensure that when a fault occurs in the turbine, the inlet ball valve serves as a guarantee for the operating safety of the turbine and promptly disconnects the water flow, thereby providing a maintenance environment for the fault maintenance of the turbine and avoiding aggravation of the turbine fault.

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.

[0021] The present invention will be further described below in conjunction with the embodiments. Example 1

[0022] A remote control optimization algorithm for a water inlet ball valve in this embodiment is as follows: Figure 1 As shown, the following steps are included: Step 1: Obtain the distribution information of the turbine and the water inlet ball valve, construct the distribution topology of the turbine and the water inlet ball valve based on the distribution information of the turbine and the water inlet ball valve, and mark the control direction of the water inlet ball valve on the distribution topology of the turbine and the water inlet ball valve; Step 2: Setting a monitoring cycle, monitoring the turbine operating status parameters in real time based on the monitoring cycle, setting a parameter screening logic, and applying the parameter screening logic to screen the monitored turbine operating status parameters; When setting the monitoring cycle, follow: ; Where: is the monitoring period; is the initial default monitoring period; is the collection of turbines in the turbine and inlet ball valve distribution topology; is the total amount of the upper water inlet ball valves of the i-th group of turbines; is the judgment function; in, Table pair Averaging, decision function When j is the direct-controlled water inlet ball valve of the i-th group of turbines, the judgment function When the value of is 1 and j is the non-directly controlled water inlet ball valve of the i-th group of turbines, the judgment function The value of is 0, It is used to indicate the complexity of turbine and water inlet ball valve distribution based on the topology level of turbine and water inlet ball valve distribution.

[0023] Step 3: obtaining the screened and processed turbine operating status parameters in real time, and analyzing the turbine operating status safety situation based on the obtained turbine operating status parameters; The parameter screening logic is expressed as: Logic1: Set several groups of turbine status safety judgment thresholds, which are respectively applied to the comparison of the turbidity and pH value of the water flow passing through the turbine, the turbine operating speed, and the turbine operating power; Logic2: Obtain any three consecutive sets of turbine operating status parameters monitored during the monitoring period, and compare the three consecutive sets of turbine operating status parameters with the corresponding turbine status safety judgment thresholds to determine whether the turbine is safe based on all turbine status safety judgment thresholds; Logic3: If the judgment result is yes, the turbine operating status parameters monitored in three consecutive monitoring cycles are discarded, otherwise, they are saved; Among them, when the three sets of turbine operating status parameters discarded in Logic3 are from the latest three sets of monitoring cycles, the turbine operating status is judged to be safe; Step 4: Obtain the safety situation analysis result of the turbine operation status, and determine whether the turbine operation status is safe according to the analysis result; The analysis logic of the safety situation of turbine operation status is expressed as: ; Where: is the safety situation value of the turbine operation status; is the turbine operating speed in the vth group of turbine operating state parameters; is the turbine operating power in the vth group of turbine operating state parameters; is the pH value of the water flowing through the turbine in the vth group of turbine operating state parameters; , is the weight; is the turbidity of the water flow passing through the turbine in the vth group of turbine operating state parameters; Among them, the latest four groups of turbine operating state parameters are recorded based on the above calculation results as The larger the safety situation value of the turbine operation status is, the safer the turbine operation status is, and vice versa.

[0024] Weight , are both > 0, and is inversely proportional to and When equal < , < ; Step 5: Set the water inlet ball valve control strategy; The judgment logic of whether the turbine operation status is safe is expressed as:

[0025] In the above formula, if either or both of formula (1) and formula (2) are true, it means that the turbine is in a safe operating state; if neither formula (1) nor formula (2) is true, it means that the turbine is in an unsafe operating state; Step 6: Setting a water inlet ball valve control strategy. When the result of determining whether the turbine operation state is safe is no, applying the water inlet ball valve control strategy to control the operation of the water inlet ball valve. The water inlet ball valve control strategy includes: Control the closing of the water inlet ball valve: the water inlet ball valve in the pipeline with a larger diameter is closed first, the water inlet ball valve close to the turbine determined to be in an unsafe operating state is closed first, and the water inlet ball valve in a higher position relative to the turbine determined to be in an unsafe operating state is closed first; The closing control of the water inlet ball valve is remotely controlled based on a wireless network.

[0026] In this embodiment, through the execution of the algorithm in the above embodiment, based on the operating status parameters of the turbine, intelligent and autonomous remote control management is provided for the water inlet ball valve, ensuring that when the turbine fails or has potential failure problems, the water inlet ball valve can be closed autonomously to disconnect the water flow, thereby providing a maintenance environment for the turbine and avoiding further unit damage losses caused by turbine failure.

[0027] See also Figure 2 As shown, the water inlet ball valve is based on the structural level: 1. The same structure of double valve seat seal is adopted. The maintenance seal pair and the working seal pair are completely interchangeable. A wear-resistant ring is added to completely avoid scratches on the water stop ring caused by metal-to-metal friction during operation. When the working seal pair is worn and leaks, the maintenance seal pair can be replaced on-site to the working seal pair if the machine cannot be shut down for a long time, thus shortening the maintenance time. The economic benefits are obvious.

[0028] 2. The valve body is split, the valve shaft is installed on the main valve body, and the force of the medium pressing on the valve shaft is borne by the main valve body. When the auxiliary valve body and the main valve body seal leak, it can be inspected under pressure without stopping the water. The valve shaft seal adopts a double seal design of U-shaped ring and PTFE packing, which has reliable sealing, small friction coefficient, small valve operating torque, and the valve shaft seal can be replaced online. 3. Materials 3. Boldly apply new materials, the valve body is made of ZG20M low alloy steel castings, the ball is made of Q355 forgings, the valve shaft is made of 20Cr13, and the water stop ring is made of ZG06Cr13Ni4Mo. The overall mechanical properties are improved, the valve is light in weight, small in size, flexible in transportation, easy to install, small in switching torque, and reduced in production cost.

[0029] Based on process level 1. The original plum blossom reinforcement ribs on the sphere are designed to be parallel to the flow channel, which makes the flow smoother, the inner and outer surfaces are smooth, and the flow rate is increased; the flow channel is manufactured by first processing and then brush plating to improve the surface hardness and roughness, reduce friction, and increase the flow capacity of the medium. The flow resistance is significantly reduced, the capacity is expanded, and the power generation is significantly increased. Example 2

[0030] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The remote control optimization algorithm for a water inlet ball valve in Example 1 is further described in detail: The distribution information of the turbine and the water inlet ball valve and the deployment position information of the turbine and the water inlet ball valve. When constructing the distribution topology of the turbine and the water inlet ball valve, all the distribution information of the turbine and the water inlet ball valve is placed in the same coordinate system for representation, and all the distribution information of the turbine and the water inlet ball valve in the coordinate system is continuously selected, and a group of turbine or water inlet ball valve distribution information is selected each time. When the distribution information of the turbine or the water inlet ball valve is selected in the coordinate system, the picking operation of the associated turbine or water inlet ball valve distribution information of the selected turbine or water inlet ball valve distribution information is further performed, so that the selected turbine or water inlet ball valve distribution information is connected with the picked turbine or water inlet ball valve distribution information to construct the construction of the distribution topology of the turbine and the water inlet ball valve; Among them, after the turbine and water inlet ball valve distribution topology is constructed, the connection between the turbine and water inlet ball valve distribution information is the pipeline connecting the turbine and the water inlet ball valve. The water inlet ball valve control direction marked on the turbine and water inlet ball valve distribution topology is placed at the connection position between the turbine and water inlet ball valve distribution information. The water inlet ball valve control direction is the direction of water flow transmitted in the pipeline connecting the turbine and the water inlet ball valve.

[0031] Through the above settings, the construction logic of the distribution topology of the turbine and the water inlet ball valve is further limited.

[0032] like Figure 1As shown, the operating state parameters of the turbine are monitored in real time through a set monitoring period. The monitoring period for monitoring the operating state parameters of the turbine is reset when the turbine and the water inlet ball valve are configured differently in the distribution topology of the turbine and the water inlet ball valve. The operating state parameters of the turbine are monitored by a water quality sensor and a torque sensor. The operating state parameters of the turbine include: turbidity and pH value of the water flow passing through the turbine, operating speed of the turbine, and operating power of the turbine. Among them, the torque sensor and the water quality sensor perform data interaction operations based on the local area network, so that the turbine operation status parameters monitored by all sensors are collected in any group of designated sensors while being marked with the location information of the parameter source sensors.

[0033] Through the above settings, the content and source of the turbine operating status parameters are further limited.

[0034] like Figure 1 As shown, the analysis operation of the safety situation of the turbine operation status is performed once each time a new turbine operation status parameter is obtained; The source of the turbine operating status parameters used to analyze the safety situation of the turbine operating status is the sensor that collects all the turbine operating status parameters. In the turbine operating status safety situation analysis stage, the turbine operating status parameters based on the four groups with the latest time series are always used among the obtained filtered and processed turbine operating status parameters.

[0035] Through the above settings, a specified interaction logic is further provided for the interaction of the turbine operating status parameters after being monitored.

[0036] In summary, during the execution of the algorithm in the above embodiment, the superior-subordinate relationship between the water inlet ball valve and the water turbine is identified by constructing the distribution topology of the water turbine and the water inlet ball valve, and the operating state safety of the water turbine is further determined by monitoring and analyzing the operating state parameters of the water turbine. Based on the determination result, the water inlet ball valve is remotely intelligently controlled to ensure that when a fault occurs in the water turbine, the water inlet ball valve serves as a guarantee for the operating safety of the water turbine, and the water flow is disconnected in time, thereby providing a maintenance environment for the fault maintenance of the water turbine and avoiding the aggravation of the fault of the water turbine.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
