Description

Technical Field

[0001] The present invention relates to the technical field of ship and marine engineering, and in particular to a remote recovery system and method applied to an oil production platform. Background Art

[0002] With the development of science and technology, the number of unmanned offshore oil platforms has increased rapidly. Whether the oil platforms can resume production in time after being shut down has an increasingly prominent impact on crude oil production.

[0003] The three core systems for remote control and resumption of production of offshore oil production platforms currently include the central control system, the integrated automatic system and the video monitoring system. When the oil production platform is shut down, the central platform can control, adjust and monitor the process through the central control system; restore the power supply and distribution system through the integrated automatic system; and confirm key locations and equipment conditions through the video monitoring system, thereby achieving the purpose of remote resumption of production.

[0004] However, when the platform loses power, the uninterruptible power supply only supplies power to the above-mentioned systems for 30 minutes. When the power supply and distribution system cannot be restored within 30 minutes, the central control system, integrated automatic system and video surveillance system lose power, and the platform loses the ability to resume production remotely.

[0005] Therefore, there is an urgent need for a remote recovery system and method for oil production platforms to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a remote recovery system and method for oil production platforms, which is used to supplement the existing remote recovery system for oil production platforms, and can transmit power to the power supply and distribution unit when the power supply and distribution unit operates normally, and continuously supply power to the integrated automatic unit and the video monitoring unit when the uninterruptible power supply does not output, so as to realize the remote recovery of the oil production platform. The many technical effects that can be produced by the preferred technical solution among the many technical solutions provided by the present invention are described in detail below.

[0024] If not, determine whether the uninterruptible power supply outage time exceeds the target duration.

[0025] Preferably, determining whether the uninterruptible power supply outage time exceeds the target duration includes determining whether the uninterruptible power supply outage time exceeds 30 minutes:

[0026] If the judgment result is no more than 30 minutes, the central control unit, power supply and distribution unit and load switching unit are powered by the battery of the uninterruptible power supply;

[0027] If the judgment result is more than 30 minutes, the uninterruptible power supply stops supplying power to the central control unit, the power supply and distribution unit, and the load switching unit; when the load switching unit detects that the uninterruptible power supply has no output, the video monitoring unit and the integrated automatic unit are automatically switched to the wind-solar complementary control box of the power generation unit.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0046] Figure 1 FIG. 1 is a schematic diagram of the structure of the remote recovery system applied to the oil production platform in this embodiment. Figure 1 As shown in the figure, the remote recovery system applied to the oil production platform is a supplement to the existing remote recovery system of the oil production platform and is installed in the existing oil production platform control system. It includes a power generation unit 1, an energy storage unit 2, a load switching unit 3, a power supply and distribution unit 4, an uninterruptible power supply 5, a central control unit 6, a production process 7, an integrated automatic unit 8 and a video monitoring unit 9.

[0047] Wherein, the power generation unit 1 is connected to the energy storage unit 2 and the load switching unit 3 respectively.

[0048] The energy storage unit 2 in this embodiment adopts a battery pack. The power generation unit 1 includes a photovoltaic module 11, a wind turbine 12, a wind-solar hybrid control box 13, and a photovoltaic grid-connected box 14. The photovoltaic module 11 and the wind turbine 12 are connected to the wind-solar hybrid control box 13; the wind-solar hybrid control box 13 is respectively connected to the photovoltaic grid-connected box 14, the load switching unit 3, and the energy storage unit 2, and the photovoltaic grid-connected box 14 is connected to the power supply and distribution unit 4.

[0049] The wind-solar hybrid control box 13 is respectively connected to the photovoltaic assembly 11, the wind turbine 12, the photovoltaic grid-connected box 14, the load switching unit 3, and the energy storage unit 2, so that the distribution, transmission, switching and storage of electric energy can be realized.

[0050] When in use, the wind-solar hybrid control box 13 can complete self-starting, and its operating modes include three modes, namely, powering the load, charging the battery in the energy storage unit 2, and transmitting electric energy to the power supply and distribution unit 4 through the photovoltaic grid-connected box 14. The wind-solar hybrid control box first powers the load, then charges the battery, and finally transmits electric energy to the power supply and distribution unit 4 through the photovoltaic grid-connected box 14.

[0051] Specifically, the uninterruptible power supply 5 is respectively connected to the power supply and distribution unit 4, the integrated automatic unit 8, the central control unit 6 and the load switching unit 3, and is used to provide power to the power supply and distribution unit 4, the central control unit 6 and the load switching unit 3. At the same time, the integrated automatic unit 8 can control the uninterruptible power supply 5.

[0052] The photovoltaic grid-connected box 14 is connected to the power supply and distribution unit 4 and the wind-solar hybrid control box 13 respectively, so that the surplus electric energy of the wind-solar hybrid control box is transmitted to the power grid.

[0053] The power supply and distribution unit 4 is respectively connected to the photovoltaic grid-connected box 14 and the uninterruptible power supply 5, and can provide power to the uninterruptible power supply 5 by receiving power from the photovoltaic grid-connected box 14. At the same time, the uninterruptible power supply 5 supplies power to the control system of the power supply and distribution unit 4.

[0054] The battery power supply time of the uninterruptible power supply 5 in this embodiment is 30 minutes. The power supply of the control circuit of the power supply and distribution unit 4 is a dual power supply, one of which is for the uninterruptible power supply 5 and the other is for the PT itself.

[0055] In this embodiment, the integrated automatic unit 8 and the video monitoring unit 9 are connected to the load switching unit 3, and the video monitoring unit 9 and the integrated automatic unit can complete self-startup, the upper-level power supply and distribution unit of the oil production platform returns to normal, and the video monitoring unit 9 and the integrated automatic unit 8 work normally, before remote resumption of production can be carried out.

[0056] By setting the load switching unit 3 to be connected to the uninterruptible power supply 5, the integrated automatic unit 8, the video monitoring unit 9 and the wind-solar complementary control box 13 respectively, intermittent switching of electric energy can be achieved. Optionally, in this embodiment, the load switching unit 3 is set to complete automatic switching of the load, and the switching time is 90 seconds.

[0057] The central control unit 6 in this embodiment is connected to the production process 7 and the uninterruptible power supply 5 respectively. The uninterruptible power supply 5 is used to supply power to the central control unit 6 , and the central control unit 6 controls the production process 7 .

[0058] As an optional implementation, the wind-solar hybrid control box 13 in this embodiment is connected to the integrated automatic unit 8 for communication. With this configuration, the central platform personnel can perform data detection and remote control on the wind-solar hybrid control box 13. The wind-solar hybrid control box 13 is connected to the photovoltaic module 11, the wind turbine 12, and the energy storage unit 2. When the uninterruptible power supply 5 fails, it can continuously supply power to the integrated automatic unit 8 and the video monitoring unit 9 to realize remote resumption of production of the oil production platform.

[0059] As an optional implementation, the load switching unit 3 includes a static switch for achieving uninterrupted load switching.

[0060] This embodiment also provides a remote production resumption method applied to an oil production platform, using the above-mentioned remote production resumption system applied to an oil production platform. When the power supply and distribution unit 4 operates normally, power is transmitted to the power supply and distribution unit 4, and when the uninterruptible power supply 5 does not output, power is continuously supplied to the integrated automatic unit 8 and the video monitoring unit 9 until the remote production of the unmanned platform is resumed.

[0061] Taking an oil production platform as an example, the remote recovery method applied to the oil production platform is described: First, determine whether the power supply and distribution unit 4 is operating normally:

[0062] When it is determined that the power supply and distribution unit 4 operates normally, the uninterruptible power supply 5 supplies power to the central control unit 6, the power supply and distribution unit 4, and the load switching unit 3 respectively. The load switching unit 3 supplies power to the video monitoring unit 9 and the integrated automatic unit 8 through the uninterruptible power supply 5; the power generation unit 1 supplies power to the load or stores energy.

[0063] Figure 2 This is the normal power supply flow chart, such as Figure 2 As shown, when the power supply and distribution unit 4 of the oil production platform operates normally, the remote recovery system of the oil production platform mainly transmits electric energy to the platform power grid.

[0064] Specifically, when the platform power supply and distribution unit 4 operates normally, the uninterruptible power supply 5 supplies power to the central control unit 6, the power supply and distribution unit 4, and the load switching unit 3 respectively, and the load switching unit 3 supplies power to the video monitoring unit 9 and the integrated automatic unit 8 through the uninterruptible power supply 5. When the sunlight is sufficient and the wind speed is greater than 8-10m / s, the photovoltaic module 11 and the wind turbine 12 start to work and generate electricity, and the electricity generated by the photovoltaic module 11 and the wind turbine 12 is input into the wind-solar hybrid control box 13.

[0065] The wind-solar hybrid control box 13 first detects whether the load is connected:

[0066] If load connection is detected, it will run with load;

[0067] If it is detected that the load is not connected, the battery voltage of the energy storage unit 2 is detected again. When it is detected that the battery voltage of the energy storage unit 2 is higher than the set voltage, the wind-solar complementary control box 13 transmits all the electric energy generated by the photovoltaic components 11 and the wind generator 12 to the photovoltaic grid-connected box 14, and the electric energy generated by the power generation unit, i.e. the wind-solar-storage integrated device, is transmitted to the platform power grid through the photovoltaic grid-connected box 14; if it is detected that the battery voltage is lower than the set voltage, energy is stored.

[0068] When it is determined that the platform power supply and distribution unit 4 is operating abnormally, the power supply to the platform power grid is stopped to supply power to the video monitoring unit 9 and the integrated self-power unit 8. Figure 3 .

[0069] Specifically, when the platform power supply and distribution unit 4 operates abnormally, the input end of the uninterruptible power supply 5 is powered off. In the first 30 minutes, the uninterruptible power supply 5 supplies power to the central control unit 6, the power supply and distribution unit 4 and the load switching unit 3 through the battery. When the battery power supply time of the uninterruptible power supply 5 is greater than 30 minutes, the uninterruptible power supply 5 stops supplying power to the central control unit 6, the power supply and distribution unit 4 and the load switching unit 3; the central control unit 6 and the power supply and distribution unit 4 are powered off and stop running, and when the load switching unit 3 detects that the uninterruptible power supply 5 has no output, the video monitoring unit 9 and the integrated automatic unit 8 are automatically switched to the wind-solar hybrid control box 13, and the wind-solar hybrid control box 13 determines whether there is a load connection, and prepares for the remote resumption of production of the oil production platform or stores energy based on the judgment result.

[0070] If a load is detected, the video monitoring unit 9 and the integrated automatic unit 8 are immediately powered. The video monitoring unit 9 and the integrated automatic unit 8 are automatically restarted after being powered, and preparations are made for the remote resumption of production of the oil production platform.

[0071] If it is detected that there is no load connected, the system continues to store energy through the energy storage unit 2.

[0072] As an optional implementation, the remote recovery method applied to an oil production platform further includes:

[0073] If the power supply and distribution unit 4 is not restored for a long time, the remote recovery system will be depleted of power, and the remote recovery system will automatically shut down, all equipment on the platform will stop running, and the remote recovery device will enter the energy storage state. When the remote recovery system completes energy storage, the remote recovery system will automatically restart and supply power to the video monitoring unit 9 and the integrated automatic unit 8. The video monitoring unit 9 and the integrated automatic unit 8 will automatically start after receiving power, and prepare for the remote recovery of the oil production platform again.

[0074] like Figure 4 As shown, when the power supply and distribution unit of the oil production platform is ready for recovery, the oil production platform starts to resume production remotely.

[0075] When the first-level power supply and distribution system on the oil production platform returns to normal and external conditions allow the power supply and distribution system on the oil production platform to be restored, first confirm the operation status of the video monitoring unit 9 and the comprehensive automatic unit 8. When both the video monitoring unit 9 and the comprehensive automatic unit 8 are in the shutdown state, it is necessary to wait for the two systems to restart automatically.

[0076] When the video monitoring unit 9 and the integrated automatic unit 8 are operating normally, the power supply and distribution unit 4 and the platform environment are observed through the video monitoring unit 9, and the protection parameters of the power supply and distribution unit 4 are observed through the integrated automatic unit 8. After confirming that the oil production platform itself has the conditions for restoring the power supply and distribution system, the integrated automatic unit 8 gives the uninterruptible power supply closing command to restore the control power of the power supply and distribution unit 4.

[0077] If the uninterruptible power supply 5 fails to close and cannot provide control power to the power supply and distribution unit 4, the power supply and distribution unit 4 itself PT automatically supplies power to the control circuit. After the control circuit of the power supply and distribution unit 4 operates normally, the integrated automatic unit 8 is used to restore the power supply and distribution unit 4 and the central control unit 6. After the power supply and distribution unit 4 and the central control unit 6 return to normal, the production process is finally restored remotely, and the platform resumes normal production.

[0078] When the power supply and distribution system cannot be restored remotely, it is necessary to wait for conditions to allow personnel to log on to the platform, and then handle the fault and resume production.

[0079] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
