[0053] Through the above - mentioned drawings, specific embodiments of the present application have been shown, and there will be a more detailed description hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0054] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0055] To clearly understand the technical solution of the present application, first, the solutions of the prior art will be introduced in detail.

[0056] Due to the long service life of the equipment and equipment aging, there is a phenomenon that the oil - gas ratio in the pressure oil tank of the speed governor does not meet the requirement after long - term operation, and it is necessary for the operator to perform air - supplementing operations. Generally, a hose is used to supplement gas into the pressure oil tank of the speed governor.

[0057] However, manually using a hose for air - supplementing takes a long time, the operation is relatively complex, and the long shutdown time of the unit causes power loss.

[0058] Therefore, aiming at the problem in the prior art that manually using a hose for air - supplementing takes a long time and the operation is relatively complex, the inventor found in the research that: detecting the oil - gas ratio of the pressure oil tank of each speed governor; if it is detected that the oil - gas ratio of the pressure oil tank does not meet the preset oil - gas ratio, determining the pressure oil tank with the non - meeting preset oil - gas ratio as the target pressure oil tank, controlling the target pressure oil tank to perform pressure - relief treatment to empty the oil and gas in the target pressure oil tank; controlling the opening of the target valve corresponding to the target pressure oil tank so that the gas in the air compressor is transported to the target pressure oil tank through the pipeline; if it is detected that the pressure of the target pressure oil tank reaches the preset pressure, controlling the closing of the target valve; controlling the opening of the oil - supply valve of the target pressure oil tank to perform oil - supplementing operation on the target pressure oil tank until the oil - gas ratio of the target pressure oil tank meets the preset oil - gas ratio, and then controlling the closing of the oil - supply valve. It can automatically detect the oil - pressure ratio. When the oil - pressure ratio does not meet the set oil - pressure ratio, it can automatically empty the oil and gas in the pressure oil tank, thereby performing automatic air - supplementing and oil - supplementing operations to make the oil - gas ratio of the pressure oil tank meet the set oil - pressure ratio, without manual detection and air - supplementing and oil - supplementing, effectively improving the air - supplementing and oil - supplementing efficiency and greatly shortening the shutdown time of the unit.

[0059] Therefore, based on the above creative findings, the inventor proposed the technical solution of the embodiment of the present application. Next, the network architecture and application scenarios of the governor control method provided in the embodiment of the present application will be introduced.

[0060] As Figure 1 shown, in the application scenario of the governor control method provided in the embodiment of the present application, it includes: a control device 101, which is used to control a governor (not shown in the figure). The control device 101 detects the oil-gas ratio of the pressure oil tank of each governor. If the control device 101 detects that the oil-gas ratio of the pressure oil tank does not meet the preset oil-gas ratio, it determines the pressure oil tank with the non-conforming oil-gas ratio as the target pressure oil tank, and controls the target pressure oil tank to perform pressure relief treatment to empty the oil and gas in the target pressure oil tank. The control device 101 controls the opening of the target valve corresponding to the target pressure oil tank, so that the gas in the air compressor is transported to the target pressure oil tank through a pipeline. The air compressor is a high-pressure air compressor. If the control device 101 detects that the pressure of the target pressure oil tank reaches the preset pressure, it controls the target valve to close. The control device 101 controls the opening of the oil supply valve of the target pressure oil tank to perform an oil replenishment operation on the target pressure oil tank until the oil-gas ratio of the target pressure oil tank meets the preset oil-gas ratio, and then controls the oil supply valve to close. It can automatically detect the oil pressure ratio. When the oil pressure ratio does not meet the set oil pressure ratio, it automatically empties the oil and gas in the pressure oil tank, thereby performing automatic air replenishment and oil replenishment operations to make the oil-gas ratio of the pressure oil tank meet the set oil pressure ratio, without manual detection and air replenishment and oil replenishment, effectively improving the air replenishment and oil replenishment efficiency and greatly shortening the unit outage time.

[0061] The embodiments of the present application will be specifically described below with reference to the accompanying drawings.

[0062] Figure 2 It is a schematic flowchart of a gas replenishment control method provided by the present application, and this method is applied to an electronic device. Among them, the electronic device can represent various forms of digital computers. Such as, cellular phones, smart phones, laptop computers, desktop computers, workstations, personal digital assistants, servers, blade servers, mainframe computers, and other suitable computers. As Figure 2 shown, this method includes:

[0063] Step 201, detecting the oil-gas ratio of the pressure oil tank of each governor.

[0064] Multiple governors are set in a hydropower station. The governor cabinets, servomotors and oil pressure devices of small and medium-sized governors are combined together, while those of large governors are separately set. The oil pressure device consists of a pressure oil tank, an oil return tank and an oil pump. The governor has been used for a long time and there is an aging situation. After long-term operation, the oil-gas ratio of the pressure oil tank does not conform. If the oil-gas ratio cannot be ensured, problems will occur to the equipment.

[0065] In this embodiment, the oil-gas ratio of the pressure oil tank of each governor in the hydropower station is detected. Generally, the oil-gas ratio is one part of oil and two parts of gas. Excessive gas will cause air intake into the main shaft cylinder, resulting in twitching, and excessive oil will reduce the pressure buffer of the governor. Therefore, the oil-gas ratio is 1:2.

[0066] Step 202: If it is detected that the oil-gas ratio of the pressure oil tank does not meet the preset oil-gas ratio, determine the pressure oil tank with the non-conforming oil-gas ratio as the target pressure oil tank, and control the target pressure oil tank to perform pressure relief treatment to empty the oil and gas in the target pressure oil tank.

[0067] In this embodiment, if it is detected that the oil-gas ratio of a certain pressure oil tank does not meet the preset oil-gas ratio, for example, does not meet the oil-gas ratio of 1:2, determine the pressure oil tank with the non-conforming oil-gas ratio as the target pressure oil tank, and perform air replenishment operation on the target pressure oil tank. Specifically, switch the governor from the operating state to the maintenance state, and control the target pressure oil tank to perform pressure relief treatment, so as to empty the oil and gas in the target pressure oil tank.

[0068] Step 203: Control the target valve corresponding to the target pressure oil tank to open, so that the gas in the air compressor is transported to the target pressure oil tank through the pipeline.

[0069] In this embodiment, control the target valve corresponding to the target pressure oil tank to open. The target valve includes: the target air replenishment valve and the target air replenishment check valve. The air compressor is a high-pressure air compressor, so that the high-pressure gas in the high-pressure air compressor is transported to the target pressure oil tank through the pipeline; among them, the air replenishment check valve is used to control the reverse flow of the gas flowing from the high-pressure air compressor into the target pressure oil tank, so that the high-pressure gas only enters and does not exit.

[0070] Step 204: If it is detected that the pressure of the target pressure oil tank reaches the preset pressure, control the target valve to close.

[0071] In this embodiment, if it is detected that the pressure of the target pressure oil tank reaches the preset pressure, at this time, the air replenishment is completed, close the target valve, and complete the air replenishment.

[0072] Step 205: Control the oil supply valve of the target pressure oil tank to open to perform oil replenishment operation on the target pressure oil tank, and control the oil supply valve to close until the oil-gas ratio of the target pressure oil tank meets the preset oil-gas ratio.

[0073] In this embodiment, after the air replenishment operation is completed, perform the oil replenishment operation. Control the oil supply valve of the target pressure oil tank to open to perform the oil replenishment operation on the target pressure oil tank, and control the oil supply valve to close until the oil-gas ratio of the target pressure oil tank meets the preset oil-gas ratio, and continue to detect the oil-gas ratio of the pressure oil tank of the governor.

[0074] In this application, the oil-gas ratio of the pressure oil tank of each governor is detected; if it is detected that the oil-gas ratio of the pressure oil tank does not meet the preset oil-gas ratio, the pressure oil tank with the oil-gas ratio not meeting the preset oil-gas ratio is determined as the target pressure oil tank, and the target pressure oil tank is controlled to perform pressure relief treatment to empty the oil and gas in the target pressure oil tank; the target valve corresponding to the target pressure oil tank is controlled to open so that the gas in the air compressor is transported to the target pressure oil tank through the pipeline; if it is detected that the pressure of the target pressure oil tank reaches the preset pressure, the target valve is controlled to close; the oil supply valve of the target pressure oil tank is controlled to open to perform oil replenishment operation on the target pressure oil tank until the oil-gas ratio of the target pressure oil tank meets the preset oil-gas ratio, and then the oil supply valve is controlled to close. It can automatically detect the oil pressure ratio. When the oil pressure ratio does not meet the set oil pressure ratio, it can automatically empty the oil and gas in the pressure oil tank, so as to perform automatic air replenishment and oil replenishment operations, so that the oil-gas ratio of the pressure oil tank meets the set oil pressure ratio, without manual detection and air replenishment and oil replenishment, effectively improving the air replenishment and oil replenishment efficiency and greatly shortening the unit shutdown time.

[0075] Figure 3 It is a schematic flowchart of another governor control method provided by this application. This method is applied to an electronic device, such as Figure 3 shown, and this method includes:

[0076] Step 301, detect the oil-gas ratio of the pressure oil tank of each governor.

[0077] There are multiple governors set in the hydropower station. The governor cabinets, servomotors and oil pressure devices of small and medium-sized governors are combined together, while those of large governors are set separately. The oil pressure device consists of a pressure oil tank, an oil return tank and an oil pump. The governors have been used for a long time and there is an aging situation. After long-term operation, the oil-gas ratio of the pressure oil tank does not meet the standard. If the oil-gas ratio cannot be ensured, problems will occur to the equipment.

[0078] In this embodiment, the oil-gas ratio of the pressure oil tank of each governor in the hydropower station is detected. Generally, the oil-gas ratio is one part of oil and two parts of gas. Too much gas will cause the main shaft cylinder to intake air and cause twitching, and too much oil will reduce the pressure buffer of the governor. Therefore, the oil-gas ratio is 1:2.

[0079] Step 302, if it is detected that the oil-gas ratio of the pressure oil tank does not meet the preset oil-gas ratio, the pressure oil tank with the oil-gas ratio not meeting the preset oil-gas ratio is determined as the target pressure oil tank, the lower limit value of the low accident oil pressure electric contact pressure gauge of the governor corresponding to the target pressure oil tank is adjusted to the preset value, and the target pressure oil tank is controlled to perform pressure relief treatment to empty the oil and gas in the target pressure oil tank.

[0080] In this embodiment, if it is detected that the oil-gas ratio of a certain pressure oil tank does not meet the preset oil-gas ratio, for example, it does not meet the oil-gas ratio of 1:2, the pressure oil tank whose oil-gas ratio does not meet the preset value is determined as the target pressure oil tank. Further, the lower limit value of the low accident oil pressure electric contact pressure gauge of the speed governor corresponding to the target pressure oil tank is adjusted to the preset value. Specifically, the lower limit value of the low accident oil pressure electric contact pressure gauge of the speed governor corresponding to the target pressure oil tank is adjusted to 0. The purpose of adjusting to 0 is to prevent the low oil pressure protection of the unit from acting due to the decrease in oil pressure during pressure relief. If the protection setting value is not adjusted, it will cause the unit protection to act. During normal operation, the pressure value is 3.6 - 4 Mpa, and the protection setting value is 3 Mpa. If the pressure is not adjusted and drops to 3 Mpa, the low oil pressure protection will act. If the protection setting value is adjusted to 0, the above situation will not occur.

[0081] Perform air and oil replenishment operations on the target pressure oil tank. Specifically, switch the speed governor from the operating state to the maintenance state, and control the target pressure oil tank to perform pressure relief treatment, so as to empty the oil and gas in the target pressure oil tank.

[0082] In a possible implementation, controlling the target pressure oil tank to perform pressure relief treatment includes:

[0083] Control the oil discharge valve corresponding to the target pressure oil tank to open, and close the oil discharge valve after emptying the oil in the target pressure oil tank; control the exhaust valve corresponding to the target pressure oil tank to open, and close the exhaust valve after emptying the gas in the target pressure oil tank.

[0084] In this embodiment, before performing air and oil replenishment, the pressure in the pressure oil tank needs to be released, and the oil and gas in the pressure oil tank need to be emptied. Control the oil discharge valve corresponding to the target pressure oil tank to open for oil discharge treatment, and close the oil discharge valve after emptying the oil in the target pressure oil tank; further control the exhaust valve corresponding to the target pressure oil tank to open for exhaust treatment, and close the exhaust valve after emptying the gas in the target pressure oil tank.

[0085] Step 303, control the target valve corresponding to the target pressure oil tank to open, so that the gas in the air compressor is transported to the target pressure oil tank through the pipeline.

[0086] In this embodiment, control the target valve corresponding to the target pressure oil tank to open. The target valve includes: the target air replenishment valve and the target air replenishment check valve, so that the gas in the high-pressure air compressor is transported to the target pressure oil tank through the pipeline; among them, the air replenishment check valve prevents the gas flowing into the target pressure oil tank from the high-pressure air compressor from flowing back, so that the high-pressure gas only goes in and does not come out.

[0087] Optionally, the method further includes:

[0088] If the air compressor is in the shutdown state, control the air compressor to start, and further control the target valve corresponding to the target pressure oil tank to open, so that the gas in the air compressor is transported to the target pressure oil tank through the pipeline; if the air compressor is in the startup state, control the target valve corresponding to the target pressure oil tank to open.

[0089] In a possible implementation manner, the target valve includes: a target air replenishing valve and a target air replenishing check valve; controlling the target valve corresponding to the target pressure oil tank to open includes:

[0090] Determine the target air replenishing valve identifier and the target air replenishing check valve identifier corresponding to the target pressure oil tank; control the target air replenishing valve corresponding to the target air replenishing valve identifier to open, and control the target air replenishing check valve corresponding to the target air replenishing check valve identifier to open.

[0091] In this embodiment, determine the target air replenishing valve identifier and the target air replenishing check valve identifier corresponding to the target pressure oil tank. The check valve can prevent gas backflow. Control the target air replenishing valve corresponding to the target air replenishing valve identifier to open, and control the target air replenishing check valve corresponding to the target air replenishing check valve identifier to open, so that the gas in the air compressor is transported to the target pressure oil tank through the pipeline.

[0092] The hydropower station includes multiple governors. Each governor is connected to the control device, and the air compressor is respectively connected to each governor through pipelines. Refer to Figure 4 , there is a pipeline connection between the first pressure oil tank 401a of the first governor and the second pressure oil tank 401b of the second governor and the air compressor 405. The pipeline is provided with a first air replenishing check valve 402a, a first air replenishing valve 403a, a second air replenishing check valve 402b, a second air replenishing valve 403b, and a total air replenishing valve 404; the control device controls the total air replenishing valve 404, the first air replenishing check valve 402a, and the first air replenishing valve 403a to open, and controls the second air replenishing check valve 402b and the second air replenishing valve 403b to be in the closed state. The gas in the air compressor 405 flows into the first pressure oil tank 401a through the pipeline to replenish air to the first pressure oil tank 401a; control the total air replenishing valve 404, the second air replenishing check valve 402b, and the second air replenishing valve 403b to open, and control the first air replenishing valve 403a and the first air replenishing check valve 402a to be in the closed state. The gas in the air compressor 405 flows into the second pressure oil tank 401b through the pipeline to replenish air to the second pressure oil tank 401b; the control device controls the total air replenishing valve 404, the first air replenishing valve 403a, the first air replenishing check valve 402a, the second air replenishing check valve 402b, and the second air replenishing valve 403b to open simultaneously. The gas in the air compressor 405 flows into the first pressure oil tank 401a and the second pressure oil tank 401b through the pipeline to replenish air to the first pressure oil tank 401a and the second pressure oil tank 401b simultaneously.

[0093] Optionally, if it is detected that the oil-gas ratio of the first pressure oil tank 401a does not conform to the preset oil-gas ratio, the first pressure oil tank 401a is determined as the target pressure oil tank, and the target air supplement valve identifier and the target air supplement check valve identifier corresponding to the target pressure oil tank are determined. Specifically, the identifier of the first air supplement valve 403a corresponding to the first pressure oil tank is determined as the target air supplement valve identifier, and the identifier of the first air supplement check valve 402a corresponding to the first pressure oil tank is determined as the target air supplement check valve identifier. The control device controls the opening of the total air supplement valve 404, the first air supplement check valve 402a and the first air supplement valve 403a, and controls the second air supplement check valve 402b and the second air supplement valve 403b to be in the closed state. The gas in the air compressor 405 flows into the first pressure oil tank 401a through the pipeline to supplement air to the first pressure oil tank 401a.

[0094] Optionally, if it is detected that the oil-gas ratio of the second pressure oil tank 401b does not conform to the preset oil-gas ratio, the second pressure oil tank 401b is determined as the target pressure oil tank, and the target air supplement valve identifier and the target air supplement check valve identifier corresponding to the target pressure oil tank are determined. Specifically, the identifier of the second air supplement valve 403b corresponding to the second pressure oil tank 401b is determined as the target air supplement valve identifier, and the identifier of the second air supplement check valve 402b corresponding to the second pressure oil tank 401b is determined as the target air supplement check valve identifier; the control device controls the opening of the total air supplement valve 404, the second air supplement check valve 402b and the second air supplement valve 403b, and controls the first air supplement valve 403a and the first air supplement check valve 402a to be in the closed state. The gas in the air compressor 405 flows into the second pressure oil tank 401b through the pipeline to supplement air to the second pressure oil tank 401b.

[0095] Optionally, if it is detected that the oil-gas ratio of the first pressure oil tank 401a and the second pressure oil tank 401b do not conform to the preset oil-gas ratio, the first pressure oil tank 401a and the second pressure oil tank 401b are determined as the target pressure oil tanks. The control device controls the total air supplement valve 404, the first air supplement valve 403a, the first air supplement check valve 402a, the second air supplement check valve 402b, and the second air supplement valve 403b to be opened simultaneously. The gas in the air compressor 405 flows into the first pressure oil tank 401a and the second pressure oil tank 401b through the pipeline to supplement air to the first pressure oil tank 401a and the second pressure oil tank 401b simultaneously.

[0096] Step 304, if it is detected that the pressure of the target pressure oil tank reaches the preset pressure, control the target valve to close.

[0097] In this embodiment, if it is detected that the pressure of the target pressure oil tank reaches the preset pressure, at this time, the air supplement is completed, and the target valve is closed to complete the air supplement.

[0098] See Figure 4If it is detected that the pressure of the first pressure oil tank 401a reaches the preset pressure, the control device controls the first air replenishment check valve 402a and the first air replenishment valve 403a to close. If there is no other pressure oil tank for replenishment at this time, the total air replenishment valve 404 is also closed.

[0099] In a possible implementation manner, controlling the target valve to close includes:

[0100] Controlling the target air replenishment valve corresponding to the target air replenishment valve identifier to close, and controlling the target air replenishment check valve corresponding to the target air replenishment check valve identifier to close.

[0101] In this embodiment, if it is detected that the pressure of the target pressure oil tank reaches the preset pressure, where the preset value can be set according to the actual situation. For example, it is set to 3 MPa. If it is detected that the pressure of the target pressure oil tank reaches 3 MPa, it indicates that the air replenishment is completed. The target air replenishment valve corresponding to the target air replenishment valve identifier is controlled to close, and the target air replenishment check valve corresponding to the target air replenishment check valve identifier is controlled to close.

[0102] Step 305, controlling the oil supply valve of the target pressure oil tank to open to perform an oil replenishment operation on the target pressure oil tank until the oil-gas ratio of the target pressure oil tank meets the preset oil-gas ratio, and then controlling the oil supply valve to close.

[0103] In this embodiment, after the air replenishment operation is completed, an oil replenishment operation is performed. The oil supply valve of the target pressure oil tank is controlled to open to perform an oil replenishment operation on the target pressure oil tank until the oil-gas ratio of the target pressure oil tank meets the preset oil-gas ratio, and then the oil supply valve is controlled to close, and the oil-gas ratio of the pressure oil tank of the governor is continuously detected.

[0104] This application can automatically detect the oil pressure ratio. When the oil pressure ratio does not meet the set oil pressure ratio, the oil and gas in the pressure oil tank are automatically emptied, so as to perform automatic air replenishment and oil replenishment operations, so that the oil-gas ratio of the pressure oil tank meets the set oil pressure ratio, without manual detection and air replenishment and oil replenishment, effectively improving the efficiency of air replenishment and oil replenishment, and greatly shortening the unit outage time.
