Description

An integrated energy storage system AC compartment for use on land drilling platforms Technical Field

[0001] This invention relates to the field of oil and gas drilling equipment and new energy storage technology, specifically to an integrated energy storage system AC compartment applied to onshore drilling platforms. Background Technology

[0002] Driven by both global energy transition and green, low-carbon development, the oil and gas industry is facing the dual challenges of energy conservation and emission reduction, as well as efficiency improvement. To address this trend, onshore drilling platforms are gradually incorporating energy storage systems to mitigate load fluctuations, achieve peak shaving and valley filling, provide emergency power, and improve power quality. This reduces reliance on grid power or generator sets (diesel / gas), effectively decreasing fuel consumption and operating costs, while simultaneously reducing carbon and CO2 emissions, thus achieving the dual goals of cost reduction and efficiency improvement, and energy conservation and emission reduction.

[0003] However, existing general-purpose containerized energy storage systems or electrical rooms face numerous challenges when applied to onshore drilling platforms: poor environmental adaptability: my country's onshore oil and gas-rich areas are mainly located in harsh environments such as deserts, Gobi, and mountains, characterized by strong winds, large temperature differences, and drastic humidity variations. Ordinary containers lack sufficient sealing, insulation, and protection levels.

[0004] High safety risks: Oil and gas drilling sites present risks of flammable and explosive gases (such as natural gas), placing extremely high demands on the explosion-proof, fire-proof, and arc-proof capabilities of electrical equipment. Existing electrical layouts and fire protection designs for energy storage compartments largely fail to consider this unique operating condition.

[0005] Insufficient integration and mobility: Drilling platform equipment is densely packed and space is limited. Traditional distributed electrical equipment layouts occupy a large area, have complex cabling connections, and are not convenient for rapid relocation and deployment.

[0006] Heat dissipation and vibration resistance issues: High-power power storage converters (PCS) generate a lot of heat during operation, and efficient heat dissipation is crucial in high-temperature, enclosed environments. At the same time, vibrations from frequent long-distance transportation (on unpaved roads) and on-site operations pose a threat to delicate power electronic equipment.

[0007] Therefore, there is an urgent need for a highly integrated, safe, reliable, and easily transportable integrated energy storage system communication compartment designed for the special working conditions of onshore drilling platforms. Summary of the Invention

[0013] Preferably, the control system module integrates an energy management unit.

[0014] Preferably, the equipment in each equipment compartment is connected to the bottom wall of the AC compartment body through an anti-vibration device; the anti-vibration device includes a mounting bracket welded between the equipment base and the bottom plate of the compartment, and a rubber shock-absorbing pad disposed inside the bracket.

[0018] Preferably, the temperature control unit also includes a temperature and humidity monitoring device and a water immersion detection device installed in each equipment compartment, and a dehumidifier is installed on the outside of the AC compartment body in conjunction with it.

[0019] The advantages of this invention compared to existing technologies are: high integration and rapid deployment: all core equipment of the energy storage system is integrated into a specially reinforced container, and a dedicated inlet / outlet room is provided, realizing "plug and play", which greatly shortens the installation and commissioning cycle at the drilling site, facilitates the hoisting and transportation of the entire container, and meets the needs of frequent relocation of drilling teams.

[0020] Excellent environmental adaptability and safety: Enhanced sealing, heat insulation, and dustproof design adapt to extreme climatic conditions; built-in explosion-proof detection and dedicated fire protection system fundamentally meet the stringent explosion-proof and fire-proof safety standards of oil drilling sites.

[0021] High-efficiency heat dissipation and reliable operation: The unique "equipment compartment + independent heat dissipation channel" structure achieves forced isolation air cooling, effectively avoiding direct wind and sand blowing on the equipment, while ensuring efficient heat dissipation of high-power converters and other equipment under high ambient temperatures, thus improving the overall reliability and lifespan of the system.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] This invention discloses an integrated energy storage system AC compartment for use on land drilling platforms, comprising an AC compartment body; the AC compartment body is divided into multiple independent equipment compartments by fireproof partitions, including a battery compartment, a converter compartment, and a control compartment; the AC compartment body is also provided with independently set air inlet and exhaust channels, the air inlet channel is equipped with a G4-grade dust filter, and the exhaust channel outlet is equipped with an explosion-proof axial flow fan, forming a forced air cooling heat dissipation circuit; the AC compartment body is also provided with a temperature control unit and a fire protection unit that are configured in conjunction with each equipment compartment.

[0031] The AC compartment body adopts a double-layer heat-insulated sandwich panel structure. The bottom of the AC compartment body is a reinforced base frame and is equipped with hoisting points. The spare compartment also includes a water-cooled machine room, a fire room, a transformer room, and an outgoing line room. The temperature control unit is located in the water-cooled machine room and includes a water-cooled main unit and water-cooled machine piping that cooperates with each equipment compartment. The fire protection unit is located in the fire room and includes a fire protection system and fire protection piping that cooperates with each equipment compartment. Each equipment compartment is also connected to an explosion-proof lighting and emergency lighting system.

[0032] The battery compartment houses an energy storage battery array, the control compartment is connected to a control system module and a DC power distribution module, and the converter compartment houses energy storage converters with a power of 0.5 MW to 2 MW. The transformer room houses the main transformer module, and the outgoing line room has a cable outlet. All external high and low voltage power cables and communication cables are introduced or led out through this cable outlet. The control system module integrates an energy management unit.

[0033] The equipment in each equipment compartment is connected to the bottom wall of the AC compartment body through an anti-vibration device; the anti-vibration device includes a mounting bracket welded between the equipment base and the bottom plate of the compartment, and a rubber shock-absorbing pad installed inside the bracket.

[0034] The forced air cooling heat dissipation circuit formed by the air intake channel and the air exhaust channel is connected to the converter compartment and the transformer room; ventilation holes are formed on the fireproof partitions in the converter compartment and the transformer room, which are connected to the forced air cooling heat dissipation circuit. The fire protection unit is also equipped with a fire detection device and a fire extinguishing agent spraying system. The fire detection device and the fire extinguishing agent spraying system are installed in each equipment compartment along with the fire protection pipeline.

[0035] The fire protection unit is also equipped with a fire detection device and a fire extinguishing agent spraying system. The fire detection device and fire extinguishing agent spraying system are installed in each equipment compartment along with the fire protection pipeline. The temperature control unit also includes a temperature and humidity monitoring device and a water immersion detection device installed in each equipment compartment. A dehumidifier is installed on the outside of the AC compartment in conjunction with it.

[0036] In a specific implementation of the present invention: as shown in Figures 1-4, the integrated energy storage system AC compartment provided by the present invention is made of a standard 20-foot or 40-foot high cube container. The interior of the compartment 1 is divided into 7 equipment rooms 201-207 and a heat dissipation channel 3 on the top by several vertical heat-insulating, fireproof and flame-retardant partitions 10.

[0037] Within equipment compartments 201-207, the following components are installed side-by-side: a water-cooled chiller unit and piping 701, a fire protection system and piping 702, an energy storage battery array, a DC power distribution module 5, a control system module 6, an energy storage converter module 4 (power can be configured from 0.5-2MW according to requirements), and a main transformer module. All modules are securely connected to the bottom plate of the compartment via a seismic mounting bracket 17 welded to the bottom. The seismic mounting bracket 17 is equipped with rubber shock-absorbing pads.

[0038] The heat dissipation channel 3 includes the heat dissipation channel on top of the converter module 4 and the main transformer module. Each heat dissipation channel is equipped with a forced air cooling system 8 consisting of two high-power axial flow fans. Its air inlet and outlet are located on the side wall of the cabin, and the outer side is equipped with a removable and washable G4-grade dust filter 9. The top of the thermal insulation, fireproof and flame-retardant partition 10 has a row of ventilation holes 11.

[0039] During operation, the heat generated by the electrical equipment (especially the converter) in the converter room 205 and main transformer room 206 raises the temperature of the indoor air. After the fan 8 in the heat dissipation channel 3 starts, a slight negative pressure is created in equipment rooms 205 and 206. Hot air is drawn into the heat dissipation channel 3 through the ventilation holes 11 on the fireproof partition 10, and then directly exhausted outside by the fan 8. Cool air is replenished from the louvers at the bottom of equipment rooms 205 and 206 (or through the adjacent battery compartment), forming a circulation. This design achieves effective heat dissipation while preventing external wind, sand, and humid air from directly contacting the core equipment.

[0040] Each compartment of hull 1 is equipped with an outward-opening door 12 for easy access and maintenance. All external cables (power lines and communication lines) are introduced through a sealed outlet 15 at the bottom of the cable outlet compartment 207 to ensure a tight seal. The bottom of the hull has four lifting points 13, conforming to the lifting specifications for container skids in the oil and gas field industry. Fire sprinklers 16 are installed on the ceiling inside the hull, linked to the fire detection and extinguishing agent spraying system in the fire protection system and pipeline 702.

[0041] The AC compartment is set up separately and is connected to the drilling rig's on-site power distribution room via high and low voltage cables and communication harnesses; it can also be combined with the gas-fired power plant to form a complete drilling rig hybrid power system, serving the microgrid of the entire onshore drilling platform.
