Description

Technical Field

[0001] The present invention relates to the technical field of power supply systems, and in particular to a method, system, electronic equipment and storage medium for preventing power swings in a fuel-driven compressor. Background Art

[0002] Some natural gas stations in China use gas turbines to drive compressors for natural gas compression. The fuel-driven compressors have several sets of vital auxiliary systems, including lubricating oil systems, ventilation systems, cooling systems, etc. The normal operation of these systems can ensure the continuous operation of the compressor unit. The electrical equipment affected by short-term external power fluctuations includes: compressor lubricating oil pumps, box cooling fans, lubricating oil cooling fans, process gas cooling fans and other equipment. Therefore, it is necessary to improve the anti-power swing capability of the fuel-driven compressor station. At present, some natural gas stations use UPS uninterruptible power supply to resist power swing, but the load capacity of this power supply is small and cannot drive the compressor lubricating oil pump, box cooling fan, lubricating oil cooling fan, process gas cooling fan and other loads at the same time, so it is impossible to ensure that the fuel-driven compressor unit is not affected by external power outages. In addition, some stations use accumulators and voltage sag protectors to temporarily ensure that the compressor lubricating oil pressure does not exceed the lower limit when the external power is cut off, but this method has a short effect time and has great limitations in the use scenario.

[0036] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0038] The solution provided by the embodiment of the present invention can be applied to any application scenario where an uninterruptible power supply is required to be provided to a compressor unit.

[0039] The embodiment of the present invention provides a possible implementation method, such as Figure 1As shown, a flow chart of a method for preventing power swing of a fuel-driven compressor is provided. The scheme can be executed by an ATS conversion cabinet, the mains is connected to a UMD module as an emergency power supply through the ATS conversion cabinet, the UMD module is connected to a guaranteed load, the ATS conversion cabinet is connected to other loads, the mains is connected to the other loads, and the guaranteed load is a load that guarantees the normal operation of the fuel-driven compressor; Figure 1 The method comprises the following steps:

[0040] Step S10, when the mains is normally powered, controlling the UMD module and the other loads to be powered by the mains, the battery pack of the UMD module is in a floating charge state, and the protection load is powered by the mains;

[0041] Step S20, when the mains power cannot be supplied normally and the disconnection time does not exceed the set time, the other loads are controlled to lose power, the battery pack of the UMD module is switched from the floating charge state to the inverter output state, and the UMD module supplies power to the protection load, and the UMD module has no power input;

[0042] Step S30, after the mains power is restored to normal power supply, the UMD module, the other loads and the safeguard load are controlled to be powered by the mains power, and the battery pack of the UMD module is switched from the inverter output state to the floating charge state.

[0043] Through the method of the present invention, when the mains power is normally supplied, the UMD module, the other loads and the protection load are all powered by the mains power, and the battery pack of the UMD module is in a floating charge state. When the mains power cannot be supplied normally and the disconnection time does not exceed the set time, the battery pack of the UMD module can be quickly switched from the floating charge state to the inverter output state. At this time, the UMD module supplies power to the protection load, which greatly ensures that the protection load is not affected by power fluctuations. After the mains power resumes normal supply, the UMD module, the other loads and the protection load are all powered by the mains power, and the battery pack of the UMD module is switched from the inverter output state to the floating charge state, thereby providing an uninterruptible power supply for the compressor unit.

[0044] The scheme of the present invention is further explained below in conjunction with the following specific embodiments. In this embodiment, a fuel-driven compressor anti-electrical shaking method is provided which can be executed by an ATS conversion cabinet. The AC power is connected to a UMD module serving as an emergency power supply through the ATS conversion cabinet. The UMD module is an uninterruptible power drive power supply device. The UMD module is connected to a safeguard load. The ATS conversion cabinet is connected to other loads (other loads can be understood as loads other than the safeguard load). The AC power is connected to the other loads. The safeguard load is a load that ensures the normal operation of the fuel-driven compressor. The safeguard load includes the compressor lubricating oil pump load, the fan load of the fuel engine housing intake and exhaust system, the fuel-driven unit lubricating oil cooling load and the process gas cooling load.

[0045] The method comprises the following steps:

[0046] Step S10, when the AC power is normally supplied, the UMD module and the other loads are controlled to be powered by the AC power, the battery pack of the UMD module is in a floating charge state, and the protection load is powered by the AC power; the UMD module has the functions of stabilizing frequency and voltage and eliminating harmonics, which can ensure the smooth and safe operation of important equipment. Important equipment can be understood as equipment corresponding to the protection load.

[0047] Step S20, when the AC power cannot supply power normally and the disconnection time does not exceed the set time, the other loads are controlled to lose power, the battery pack of the UMD module is switched from the floating charge state to the inverter output state, and the UMD module supplies power to the guaranteed load, and the UMD module has no power input; thereby ensuring the normal operation of the unit during the external power (AC power) flash failure and interruption.

[0048] Step S30, after the mains power is restored to normal power supply, the UMD module, the other loads and the safeguard load are controlled to be powered by the mains power, and the battery pack of the UMD module is switched from the inverter output state to the floating charge state.

[0049] Optional, see Figure 2 and Figure 3 The ATS conversion cabinet is also connected to a generator.

Then, between S20 and S30, the method further includes:

[0050] S21, switching the generator as an input power source to supply power to the UMD module and the other loads.

[0051] The above setting time can be set based on actual needs, for example, 30s.

[0052] Optionally, after the mains power is disconnected for more than the set time, the method further includes:

[0053] Control the battery pack of the UMD module to be in a floating charge state, and control the protection load to be powered by the generator;

[0054] After the mains power is restored to normal power supply, the mains power is automatically switched as the input power source, and the UMD module, the other loads and the safeguard load are controlled to be powered by the mains power, and the battery pack of the UMD module is in a floating charge state. At this time, the fuel-driven compressor can continue to operate when the generator is running stably.

[0055] Based on Figure 1 Based on the same principle as the method shown in , the embodiment of the present invention also provides a fuel-driven compressor anti-electrical sway system 20, such as Figure 3 As shown in , the fuel-driven compressor anti-power swing system 20 may include a mains power supply, a generator, an ATS conversion cabinet, a UMD module, a protection load and other loads;

[0057] The ATS conversion cabinet is used to control the UMD module and the other loads to be powered by the mains when the mains is normally powered. The battery pack of the UMD module is in a floating charge state, and the load is protected to be powered by the mains; and

[0058] When the mains power cannot be supplied normally and the disconnection time does not exceed the set time, at this time, if the ATS conversion cabinet is in normal mode, the other loads are controlled to lose power, the battery pack of the UMD module is switched from the floating charge state to the inverter output state, and the UMD module supplies power to the protection load, and the UMD module has no power input; and

[0059] After the mains power is restored to normal power supply, the UMD module, the other loads and the safeguard load are controlled to be powered by the mains power, and the battery pack of the UMD module is switched from the inverter output state to the floating charge state.

[0060] Optionally, the system further comprises a generator connected to the ATS conversion cabinet;

At this time, the ATS conversion cabinet detects the backup power source (generator) incoming power, and the generator supplies power to the UMD module and the other loads;

[0062] The ATS conversion cabinet is also used to control the battery pack of the UMD module to be in a floating charge state, and control the guaranteed load to be powered by the generator; and

[0063] After the mains power is restored to normal power supply, the mains power is automatically switched as the input power supply, and the UMD module, the other loads and the safeguard load are controlled to be powered by the mains power, and the battery pack of the UMD module is in a floating charge state.

It has been applied to a fuel-driven compressor in a gas transmission station. The anti-power swing effect is very good.
