Description

Technical Field

[0001] The present invention relates to the technical field of inlet ball valves, and particularly to an optimization method for remote control of an inlet ball valve. Background Art

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

[0003] The invention patent with the application number 201410845814.5 discloses a control method for a water turbine inlet ball valve, which is characterized in that: the method includes the following steps: the water turbine inlet ball valve of the present invention is driven to open hydraulically and relies on the potential energy of a heavy hammer to achieve closing, and its actions are valve opening, locking, and valve closing, specifically as follows: 1. For valve opening, the acting force of the hydraulic control station and the lifting cylinder of the servomotor is utilized to drive the opening and closing member to rotate 90° through the rocker arm, heavy hammer, and valve stem. At the same time, the acting force of the hydraulic control station and the lifting cylinder also vertically lifts the heavy hammer through the rocker arm, converting the gravity of the heavy hammer into potential energy to prepare the power for valve closing; 2. Locking is carried out by manual mechanical locking or automatic mechanical locking; when manual mechanical locking is adopted, after the regulating valve is opened in place, the locking pin is directly inserted or pulled out, and at the same time, a signal indicating device for manual locking insertion or extraction is provided; when automatic mechanical locking is adopted, after the valve is fully opened, the acting force of the transmission cylinder first drives the mechanical locking shaft to be inserted 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 completely automatic under the action of a series of travel switches, and under the condition that the electromagnet is not de-energized, the electromagnetic locking shaft and the mechanical locking shaft can achieve safe control.

[0004] This application lies in articulating the problem that: "Due to the special requirements of water turbine operation, the general series of ball valves cannot meet the usage requirements of the working condition system during the operation of hydropower stations, resulting in the phenomenon that the unit cannot operate from time to time."

[0005] However, the control application of the inlet ball valve mainly serves the daily operation of the water turbine. When the water turbine fails, the inlet ball valve switches the water flow to provide a maintenance environment for the maintenance of the water turbine. At present, although the inlet ball valve has a remote control system, its autonomy is poor and it cannot adaptively control the water flow better in accordance with the operating state of the water turbine, reducing the losses caused by water turbine failures. Summary of the Invention

[0006] In view of the above-mentioned drawbacks existing in the prior art, the present invention provides an optimization method for remote control of an inlet ball valve, which solves the technical problems raised in the above background art.

[0007] To achieve the above object, the present invention is realized through the following technical solutions:

[0008] A method for optimizing the remote control of an inlet ball valve, comprising:

[0009] Obtain the distribution information of the water turbine and the inlet ball valve, construct the distribution topology of the water turbine and the inlet ball valve based on the distribution information of the water turbine and the inlet ball valve, and mark the control direction of the inlet ball valve on the distribution topology of the water turbine and the inlet ball valve; set the monitoring period, and based on the monitoring period, monitor the operating state parameters of the water turbine in real time, set the parameter screening logic, and apply the parameter screening logic to screen the monitored operating state parameters of the water turbine; obtain the operating state parameters of the water turbine after screening and processing in real time, and analyze the safety situation of the operating state of the water turbine based on the obtained operating state parameters of the water turbine; obtain the analysis result of the safety situation of the operating state of the water turbine, and determine whether the operating state of the water turbine is safe according to the analysis result; set the control strategy of the inlet ball valve; when the determination result of whether the operating state of the water turbine is safe is no, apply the control strategy of the inlet ball valve to control the operation of the inlet ball valve.

[0010] Furthermore, for the distribution information of the water turbine and the inlet ball valve and the deployment position information of the water turbine and the inlet ball valve, when constructing the distribution topology of the water turbine and the inlet ball valve, place all the distribution information of the water turbine and the inlet ball valve in the same coordinate system for representation, and continuously select all the distribution information of the water turbine and the inlet ball valve in the coordinate system. Each time, select a set of distribution information of the water turbine or the inlet ball valve. When the distribution information of the water turbine or the inlet ball valve is selected in the coordinate system, further perform the picking operation of the associated distribution information of the water turbine or the inlet ball valve of the selected distribution information of the water turbine or the inlet ball valve, and connect the selected distribution information of the water turbine or the inlet ball valve with the picked distribution information of the water turbine or the inlet ball valve to construct the distribution topology of the water turbine and the inlet ball valve;

[0011] Among them, after the distribution topology of the water turbine and the inlet ball valve is completed, the connection line between the distribution information of the water turbine and the inlet ball valve is the connecting pipe between the water turbine and the inlet ball valve. The control direction of the inlet ball valve marked on the distribution topology of the water turbine and the inlet ball valve is placed at the position of the connection line between the distribution information of the water turbine and the inlet ball valve, and the control direction of the inlet ball valve is the direction of the water flow transmitted in the connecting pipe between the water turbine and the inlet ball valve.

[0012] Furthermore, when setting the monitoring period, it obeys:

[0013]

[0014] In the formula: d is the monitoring period; d 0 is the initial default monitoring period; n is the set of water turbines in the distribution topology of the water turbine and the inlet ball valve; m i is the total amount of the upstream inlet ball valves of the i-th group of water turbines; f(j) is the decision function;

[0015] Among them, Table pair When averaging and determining the function f(j), when j is the directly controlled inlet valve of the i-th group of turbines, the value of the determination function f(j) is 1, and when j is the non-directly controlled inlet valve of the i-th group of turbines, the value of the determination function f(j) is 0. It is used to represent the complexity of the distribution of turbines and inlet valves based on the topological level of the turbine and inlet valve distribution.

[0016] Furthermore, 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 configuration of the turbine and inlet valve changes in the turbine and inlet valve distribution topology. 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: the turbidity and pH value of the water flow passing through the turbine, the operating speed of the turbine, and the operating power of the turbine.

[0017] Among them, the torque sensor and the water quality sensor perform data interaction operations based on the local area network, so that the operating state parameters of the turbine monitored by all sensors are collected in any group of specified sensors under the condition of marking the position information of the parameter source sensor.

[0018] Furthermore, the parameter screening logic is expressed as:

[0019] Logic1: Set several groups of turbine state safety determination thresholds and apply them to the comparison of the turbidity and pH value of the water flow passing through the turbine, the operating speed of the turbine, and the operating power of the turbine respectively.

[0020] Logic2: Obtain the operating state parameters of the turbine monitored in any three consecutive monitoring periods, apply the three consecutive operating state parameters of the turbine to compare with the corresponding turbine state safety determination thresholds, and determine whether the turbine is safe based on all turbine state safety determination thresholds.

[0021] Logic3: If the determination result is yes, discard the operating state parameters of the turbine monitored in the three consecutive monitoring periods obtained, otherwise, save them.

[0022] Among them, when the source of the three groups of operating state parameters of the turbine discarded in Logic3 is the latest three monitoring periods, the operating state of the turbine is determined to be safe.

[0023] Furthermore, the analysis operation of the safety situation of the turbine operating state is executed once every time new operating state parameters of the turbine are obtained.

[0024] The source of the operating state parameters of the water turbine for analyzing the safety situation of the water turbine operation is the sensors that collect all the operating state parameters of the water turbine. During the safety situation analysis stage of the water turbine operation, the four groups of water turbine operating state parameters with the latest time series are always applied from the filtered and processed water turbine operating state parameters obtained.

[0025] Furthermore, the analysis logic of the safety situation of the water turbine operation is expressed as:

[0026]

[0027] In the formula: χ is the safety situation value of the water turbine operation state; s v is the operating speed of the water turbine in the v-th group of water turbine operating state parameters; p v is the operating power of the water turbine in the v-th group of water turbine operating state parameters; pH v is the pH value of the water flow passing through the water turbine in the v-th group of water turbine operating state parameters; ω v 、ω v+1 are weights; N v is the turbidity of the water flow passing through the water turbine in the v-th group of water turbine operating state parameters;

[0028] Among them, the four groups of the latest water turbine operating state parameters are recorded as χ 1 、χ 2 、χ 3 according to the calculation result of the above formula. The larger the safety situation value of the water turbine operation state, the safer the water turbine operation state is. On the contrary, the less safe it is.

[0029] Furthermore, the determination logic of whether the water turbine operation state is safe is expressed as:

[0030]

[0031] In the above formula, if either or both of formula (1) and formula (2) hold, it indicates that the water turbine operation state is safe. If neither formula (1) nor formula (2) holds, it indicates that the water turbine operation state is unsafe.

[0032] Furthermore, the control strategy of the inlet ball valve includes:

[0033] Controlling the inlet ball valve to close: The inlet ball valve with a larger pipe diameter where it is located is closed first, the inlet ball valve closer to the water turbine determined to be in an unsafe operation state is closed first, and the inlet ball valve at a higher terrain relative to the water turbine determined to be in an unsafe operation state is closed first;

[0034] The closing control of the inlet ball valve is remotely controlled based on a wireless network.

[0035] Adopting the technical solution provided by the present invention, compared with the known public technology, it has the following

[0036] Beneficial effects:

[0037] The present invention provides an optimization method for remote control of an inlet ball valve. During the execution of this algorithm, by constructing the distribution topology of the water turbine and the inlet ball valve, the superior-subordinate relationship between the inlet ball valve and the water turbine is identified. Further, through the monitoring and analysis of the operating state parameters of the water turbine, the safety of the operating state of the water turbine is determined. Then, based on the determination result, the inlet ball valve is remotely and intelligently controlled to ensure that when a fault occurs in the water turbine, as a guarantee for the safe operation of the water turbine, the water flow is cut off in time, providing a maintenance environment for the fault maintenance of the water turbine and avoiding the aggravation of the water turbine fault.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0042] The following further describes the present invention with reference to the embodiments.

[0043] Embodiment 1:

[0044] An optimization method for remote control of an inlet ball valve in this embodiment, as Figure 1 shown, includes the following steps:

[0045] Step 1: Obtain the distribution information of the water turbine and the inlet ball valve. Based on the distribution information of the water turbine and the inlet ball valve, construct the distribution topology of the water turbine and the inlet ball valve, and mark the control direction of the inlet ball valve on the distribution topology of the water turbine and the inlet ball valve;

[0046] Step 2: Set the monitoring period. Based on the monitoring period, monitor the operating state parameters of the water turbine in real time. Set the parameter screening logic, and apply the parameter screening logic to screen the monitored operating state parameters of the water turbine;

[0047] When setting the monitoring period, it is subject to:

[0048]

[0049] In the formula: d is the monitoring period; d 0 is the initial default monitoring period; n is the set of water turbines in the distribution topology of the water turbine and the inlet ball valve; m i is the total amount of the upper inlet ball valves of the i-th group of water turbines; f(j) is the decision function;

[0050] Among them, The table takes the average. In the decision function f(j), when j is the directly controlled inlet ball valve of the i-th group of water turbines, the value of the decision function f(j) is 1, and when j is the non-directly controlled inlet ball valve of the i-th group of water turbines, the value of the decision function f(j) is 0, which is used to represent the complexity of the distribution of the water turbine and the inlet ball valve based on the distribution topology level of the water turbine and the inlet ball valve;

[0051] Step 3: Obtain the operating state parameters of the water turbine after screening and processing in real time, and analyze the safety situation of the operating state of the water turbine based on the obtained operating state parameters of the water turbine;

[0052] The parameter screening logic is expressed as:

[0053] Logic1: Set several groups of water turbine state safety determination thresholds, and apply them to the comparison of the turbidity and pH value of the water flow passing through the water turbine, the operating speed of the water turbine, and the operating power of the water turbine respectively;

[0054] Logic2: Obtain the operating state parameters of the water turbine monitored in any three consecutive monitoring periods, and apply the three consecutive operating state parameters of the water turbine to compare with the corresponding water turbine state safety determination thresholds to determine whether the water turbine is safe based on all the water turbine state safety determination thresholds;

[0055] Logic3: If the determination result is yes, discard the operating state parameters of the water turbine monitored in the three consecutive monitoring periods obtained, otherwise, save them;

[0056] Among them, the sources of the three sets of discarded turbine operating state parameters in Logic3 are that the turbine operating state was determined to be safe during the latest three monitoring periods;

[0057] Step 4: Obtain the analysis result of the safety situation of the turbine operating state, and determine whether the turbine operating state is safe according to the analysis result;

[0058] The analysis logic of the safety situation of the turbine operating state is expressed as:

[0059]

[0060] In the formula: χ is the safety situation value of the turbine operating state; s v is the operating speed of the turbine in the v-th set of turbine operating state parameters; p v is the operating power of the turbine in the v-th set of turbine operating state parameters; pH v is the pH value of the water flow passing through the turbine in the v-th set of turbine operating state parameters; ω v 、ω v+1 are weights; N v is the turbidity of the water flow passing through the turbine in the v-th set of turbine operating state parameters;

[0061] Among them, the calculation results of the operating state parameters of the latest four sets of turbines are recorded as χ 1 、χ 2 、χ 3 , the larger the safety situation value of the turbine operating state, the safer the turbine operating state; conversely, the less safe.

[0062] The weights ω v 、ω v+1 are both > 0, and are inversely proportional to |pH v -7|, and when |pH v -7| is equal to |pH v+1 -7| and pH v <pH v+1 , ω v+1 <ω v ;

[0063] Step 5: Set the control strategy for the inlet ball valve;

[0064] The determination logic of whether the turbine operating state is safe is expressed as:

[0065]

[0066] In the above formula, if either or both of formula (1) and formula (2) hold, it means the turbine operating state is safe; if both formula (1) and formula (2) do not hold, it means the turbine operating state is unsafe;

[0067] Step 6: When the determination result of whether the operation state of the water turbine is safe is no, apply the inlet ball valve control strategy to control the operation of the inlet ball valve;

[0068] The inlet ball valve control strategy includes:

[0069] Control the inlet ball valve to close: The inlet ball valve with a larger pipe diameter where it is located is closed first, the inlet ball valve closer to the water turbine determined to be in an unsafe operation state is closed first, and the inlet ball valve at a higher elevation relative to the water turbine determined to be in an unsafe operation state is closed first;

[0070] The closing control of the inlet ball valve is remotely controlled based on a wireless network.

[0071] In this embodiment, through the execution of the algorithm in the above embodiment, based on the operation state parameters of the water turbine, intelligent and autonomous remote control management is brought to the inlet ball valve, ensuring that when the water turbine fails or there are potential fault problems, the inlet ball valve can close autonomously, cut off the water flow, provide a maintenance environment for the maintenance of the water turbine, and avoid further damage and losses to the unit caused by the failure of the water turbine.

[0072] See Figure 2 As shown, this inlet ball valve is based on the structural level:

[0073] 1. Adopt the same double-valve seat sealing structure. The maintenance seal pair and the working seal pair can be completely interchanged, and a wear-resistant ring is added, which can completely avoid abrasion caused by metal-to-metal friction during the operation of the water stop ring. When the working seal pair wears and leaks, the maintenance seal pair can be replaced on-site to the working seal pair without long-term shutdown, shortening the maintenance time. The economic benefits are obvious.

[0074] 2. The valve body is of a partial split type. The valve shaft is installed on the main valve body, and the force of the medium pressing against the valve shaft is borne by the main valve body. When there is a leak in the seal between the sub-valve body and the main valve body, it can be repaired under pressure without stopping the water. The valve shaft seal adopts a double-seal design of U-shaped ring and tetrafluoro packing, with reliable sealing, small friction coefficient, small valve operation torque, and the valve shaft seal can be replaced online. 3. Materials

[0075] 3. Boldly apply new materials. The valve body is made of ZG20M low alloy steel casting, the ball is made of Q355 forging, the valve shaft is made of 20Cr13, and the water stop ring is made of ZG06Cr13Ni4Mo. The mechanical properties are generally improved. The overall weight of the valve is light, the volume is small, the transportation is flexible, the installation is convenient, the opening and closing torque is small, and the production cost is reduced.

[0076] Based on the process level

[0077] 1. The original plum blossom stiffening rib plates on the sphere are designed into rib plates parallel to the flow channel, resulting in a smoother flow pattern, smooth inner and outer surfaces, and increased flow rate; the flow channel is manufactured using a process of machining first and then brush plating to improve surface hardness and roughness, reduce friction, and increase the flow capacity of the medium. The flow resistance is significantly reduced, capacity is increased, and power generation is significantly increased.

[0078] Example 2:

[0079] At the specific implementation level, based on Example 1, this example refers to Figure 1 to further specifically illustrate an optimized method for remote control of an inlet ball valve in Example 1:

[0080] The distribution information of the water turbine and the inlet ball valve and the deployment position information of the water turbine and the inlet ball valve. When constructing the distribution topology of the water turbine and the inlet ball valve, all the distribution information of the water turbine and the inlet ball valve is placed in the same coordinate system for representation, and all the distribution information of the water turbine and the inlet ball valve in the coordinate system is continuously selected. Each time a group of distribution information of the water turbine or the inlet ball valve is selected, when the distribution information of the water turbine or the inlet ball valve is selected in the coordinate system, a pick-up operation of the associated distribution information of the water turbine or the inlet ball valve of the selected distribution information of the water turbine or the inlet ball valve is further performed, so that the selected distribution information of the water turbine or the inlet ball valve is connected to the picked-up distribution information of the water turbine or the inlet ball valve to construct the construction of the distribution topology of the water turbine and the inlet ball valve;

[0081] Among them, after the distribution topology of the water turbine and the inlet ball valve is completed, the connection lines between the distribution information of the water turbine and the inlet ball valve are the connecting pipes between the water turbine and the inlet ball valve. The control direction of the inlet ball valve marked on the distribution topology of the water turbine and the inlet ball valve is placed at the connection line position between the distribution information of the water turbine and the inlet ball valve. The control direction of the inlet ball valve is the direction of the water flow transmitted in the connecting pipe between the water turbine and the inlet ball valve.

[0082] Through the above settings, the construction logic of the distribution topology of the water turbine and the inlet ball valve is further defined.

[0083] As Figure 1 shown, the operating state parameters of the water turbine are monitored in real time through a set monitoring period. The monitoring period for monitoring the operating state parameters of the water turbine is reset when configuration changes occur to the water turbine and the inlet ball valve in the distribution topology of the water turbine and the inlet ball valve. The operating state parameters of the water turbine are monitored by a water quality sensor and a torque sensor. The operating state parameters of the water turbine include: the turbidity and pH value of the water flow passing through the water turbine, the operating speed of the water turbine, and the operating power of the water turbine;

[0084] Among them, the torque sensor and the water quality sensor perform data interaction operations based on a local area network, enabling the operating state parameters of the water turbine monitored by all sensors to be collected at any designated set of sensors with the position information of the sensor from which the parameters are sourced marked.

[0085] Through the above settings, the content and source of the operating state parameters of the water turbine are further defined.

[0086] Such as Figure 1 shown, the analysis operation of the safety situation of the water turbine operating state is performed once each time new operating state parameters of the water turbine are obtained;

[0087] The source of the operating state parameters of the water turbine used to analyze the safety situation of the water turbine operating state is the sensor that collects all the operating state parameters of the water turbine. During the analysis stage of the safety situation of the water turbine operating state, the four sets of operating state parameters of the water turbine that are the latest based on time series among the obtained and filtered operating state parameters of the water turbine are always applied.

[0088] Through the above settings, a specified interaction logic is further provided for the interaction of the operating state parameters of the water turbine after being monitored.

[0089] In summary, during the execution of the algorithm in the above embodiments, by constructing the distribution topology of the water turbine and the inlet ball valve, the superior-subordinate relationship between the inlet ball valve and the water turbine is identified. Further, through the monitoring and analysis of the operating state parameters of the water turbine, the operating state safety of the water turbine is determined. Then, based on the determination result, remote intelligent control of the inlet ball valve is performed to ensure that when a fault occurs in the water turbine, the inlet ball valve, as a guarantee for the operating safety of the water turbine, cuts off the water flow in time, provides a maintenance environment for the fault repair of the water turbine, and avoids the aggravation of the water turbine fault.

[0090] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these 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.
