Frequency Conversion Fracturing Integrated Pumping and Speed Regulating Equipment Introduction

l  Technical Background

Fracturing pumping equipment is essential equipment for oil and gas field development. Traditional fracturing equipment generally uses a diesel engine to drive the fracturing pump through a transmission box. The speed of the fracturing pump is adjusted by changing the speed of the diesel engine and the gear of the transmission box. Ultimately the traditional equipment controls the discharge volume of the fracturing fluid injected into the well. With the expansion of shale gas exploitation in recent years, it has become a trend to substitute diesel engines and transmission boxes with electric machines to directly drive fracturing pumps. However, a technical flaw is that the current electric drive fracturing equipment usually requires separate transportation and layout of the power distribution room and VFD room, which covers a large area. All pieces of equipment take up too much space because they exist independently, including the input cabinet, output cabinet, rectifier and filter cabinet, motor, and inverter. The traditional electric drive is separated from the frequency converter, and each operates in its state, and all pieces of equipment cannot be integrated as a whole. As a result, it requires more space on site, generating cluttered cable rope, high electromagnetic harmonic interference, creating inconvenience to setup high-protection, and difficulty in equipment maintenance.

l  Electric Drive Fracturing Inverter Solution

The integrated frequency conversion device is a speed control device for fracturing pumping equipment, which solves problems of the current electric fracturing equipment requiring separate transportation and layout of the power distribution room and VFD room.

The electric drive fracturing frequency converter is a core power control component in the electric drive fracturing system.

Product Advantage:

•        Advanced performance, safety, and reliability

•        Strong anti-interference ability

•        Reasonable layout

•        Simple operation and easy maintenance

•        High torque at low speed for high voltage electric drive inverter fracturing equipment

•        Wide environmental adaptability

By optimizing the electric drive fracturing inverter solution, the high voltage inverter speed control device can achieve high energy conversion efficiency, strong transport performance, lightweight, excellent system integration, good heat dissipation, convenient communication, and other practical functions.

l  Structural Design

The integrated inverter device utilizes a high-speed data processing chip to achieve inverter control function and Integral modular design. The entire inverter control device is an independent module with an integrated design and compact installation space, which can be installed on the fracturing equipment skid. Hence, there is no need for an additional transport distribution room and VFD room to a work site, significantly reducing harmonic interference caused by variable frequency drive mode, flexible assembly, and efficiency in transportation, protection, and maintenance. The overall design of the inverter effectively improves the reliability of the system.

l  Technical Design

The control system of an integrated frequency conversion fracturing pumping equipment includes a high-voltage electric input unit, an integrated container, a frequency conversion integrated machine, and peripheral equipment.

The frequency conversion machine includes a detection, temperature control system, and frequency converter. The distribution of the power supply in the integrated equipment consists include input cabinet, output cabinet, transformer, rectifier filter unit, and power unit, which converts high-voltage AC power into low-voltage smooth DC power for the power unit, and the power unit inverts into AC power to drive the motor.

The main interface is a touch screen, a real-time display of monitoring data, and related operations. The main interface will automatically switch windows when entering the corresponding operating mode. The main interface is installed on the integrated inverter, which displays or sets the inverter status parameters.

The central controller ensures the real-time of the system, enhances the system response speed, and effectively resolves the signal and analyzes the data. The central controller adopts an ARM9 chip-embedded motherboard to control the parameters and functions of the inverter.

Overall, the frequency conversion integrated machine integrates the detection system, temperature control system, and frequency converter.

l  Technical difficulties of medium voltage variable frequency drive system

Compared with low-voltage (<=600V) drives, medium-voltage drives have higher technical requirements and challenges in many aspects. Some insignificant or even non-existent problems in low-voltage is a critical issue that must be resolved in medium-voltage transmission. These technical difficulties include the technical requirements related to the power quality of the rectifier on the network side, the technical challenges associated with the motor-side inverter design switching device limitations, and the overall requirements of the drive system.

Generally speaking, medium voltage transmission covers power levels from 0.4 to 40MW and voltage levels from 2.3 to 13.8KVV.However, its power range can exceed a maximum of 100MW, and the installed medium voltage transmission systems are mainly concentrated in the range of 1 to 4MW and 3.3 to 6.6kV levels. Compared with low voltage (<=600V) transmission, the technical difficulties of medium voltage transmission include technical requirements related to the network side rectifier, technical difficulties related to motor-side inverter design, limitations of switching devices, challenges related to motor-side inverter design, limitations of switching devices and overall requirements of the transmission system.

The overall requirements for MV drive systems include high efficiency, low cost, small form factor, high reliability, adequate fault protection, easy installation, self-testing, and minimal downtime. Some special applications may also require high dynamic performance, regenerative braking, or four-quadrant operation.
