The largest single building in Asia-Xinjiang Nilka's 4GW wind power PV project was successfully connected to the grid On May 28, 2024, the first phase of the 2GW PV project of the 4GW wind power and PV integration project in Nilka, Xinjiang, was successfully connected to the grid. It is the first successful grid-connected project in the 13GW project of Xinjiang's renewable energy base, achieving a "good start" of 531 grid connections and marking the successful grid connection of the largest single wind power and PV project in Asia. The project covers an area of about 120,000,000㎡, with a construction of 3.2GW of PV installed capacity and 0.8GW of wind power installed capacity, and is equipped with four 220kV collection stations and two 110kV booster stations. It is reported that after the project is fully put into operation, it is expected to provide 8 billion kWh of clean electricity annually, which can save 2.2943 million tons of raw coal and reduce carbon dioxide emissions by 6.266 million tons, playing an important role in improving the local energy supply structure. The successful grid connection of the first phase of the 2GW photovoltaic project in Nilka, Xinjiang, will effectively promote the strengthening, optimization and expansion of the green energy industry, and help achieve the goal of installing more than 20GW of capacity and acquiring more than 20GW of resources by the end of the year, contributing to the country's efforts to accelerate the construction of a renewable system. #FGI #Renewable #CleanEnergy #SolarProject #windfarm #PVproject

Application of FGi Power Inverter in Coal Mine Belt Conveyor Traditional belt conveyors use industrial frequency operation. Due to the long-term industrial frequency operation of the motor and the problems of hydraulic coupling efficiency, the operation of the belt conveyor is very uneconomical. At the same time, since the motor cannot use soft start and soft stop, it will produce severe impact on the machinery and accelerate the wear of the machinery. There are also problems such as wear and maintenance of belts and hydraulic couplings, which will bring a large amount of expenses to the enterprise. The FD2000 inverter drives the belt conveyor in good operation and embodies the following advantages: ◆ Speed synchronization and current balance. The torque of the slave is consistent with that of the host. The current difference is within 5A. The slave will not have overvoltage caused by mismatch with the host speed. ◆ Simple parameters. There are fewer parameters to be set and adjusted, and the sensitivity to motor parameters is low, which is very suitable for one master and multiple slaves application scenarios. ◆ Excellent soft start/stop characteristics. The acceleration/deceleration time (0-60min) is continuously adjustable, and S-type acceleration and deceleration can be achieved, effectively reducing the start-stop impact. ◆ Smooth heavy load start. The belt conveyor can be stopped and restarted at any time during the coal transportation process without any problems. The low-frequency operation can output a maximum of 1.5 times the rated torque. As the power drive equipment of the coal mine belt conveyor, the FD2000 series inverter solves various problems of the belt conveyor in coal production with its advantages such as high efficiency, low noise, large starting torque, high reliability, good speed regulation performance, and maintenance-free. #VFD #BELTCONVEYOR #FGi

Since the belt conveyor motor has been running at industrial frequency for a long time, it cannot start and stop softly, and the belt conveyor uses a hydraulic coupling to realize the soft start of the belt, which makes the voltage of the power grid fluctuate violently. The internal mechanical impact of the motor is severe, the heat and wear are large, and there are problems such as large maintenance and repair workload, high energy consumption, and high cost. In addition, due to the short start-up time and large loading force of the belt conveyor, the belt is easy to break and age, so a high-strength belt has to be selected, which increases the cost. After the application of the belt conveyor inverter, the long-distance transmission of the coal conveyor trestle belt and the power balance between the motors are realized, and the one-button start of each conveyor belt is realized, which reduces the loss and greatly improves the work efficiency. The photo is the application load of 19 high-voltage permanent magnet synchronous motor belt conveyors in a large coal mine loading station and coal handling trestle project.

High Voltage cascade energy storage system(ESS)

FGi Industrial and Commercial energy storage system was put into operation in a hospital. If the hospital's power grid suddenly went out, our industrial and commercial energy storage system could automatically switch from grid-connected to off-grid to provide emergency backup power supply. This ensured that the hospital's key applications were not affected by external network power outages and ensured the stability of key loads.

For a long time, ball mills have been widely used in the mining grinding process to grind raw materials. Generally, they are started by hydraulic coupling. The large starting current has a greater impact on the equipment and the power grid. At the same time, it is easy to cause excessive grinding of materials at power frequency, long grinding cycle, low grinding efficiency, and high power consumption per unit product. Using a frequency converter to drive the ball mill can make the ball mill system start smoothly, have higher grinding efficiency, increase output, and reduce energy consumption.

The world's first ultra-high altitude, ultra-low temperature, and extremely weak power grid, the intelligent string-type grid-type photovoltaic storage power station has been successfully connected to the grid for power generation. The high altitude of the project site leads to low air pressure and thin air. In addition, the climate is cold and dry, and the temperature difference between day and night is very large. These environmental characteristics have a significant impact on the insulation performance and temperature rise of the equipment. In order to cope with these harsh environments, FGi actively developed and launched targeted solutions. After the completion of the project, the average annual online power generation during the operation period of the power station is expected to be 53.0324 million kW·h, which will provide a large amount of clean energy for Gai Ze County, while reducing the consumption of fossil resources and reducing the pollution of the environment caused by harmful gases emitted by coal burning.

Due to the load characteristics of steel smelting, the use of arc furnaces, refining furnaces and other equipment in smelting conditions will cause a variety of power quality problems, such as harmonic problems, voltage fluctuations and flicker problems, and three-phase imbalance problems; these problems will cause electrical equipment to heat up, reduce equipment life, and interfere with communication systems and automatic control systems. Harmonics will generate noise in communication lines, affecting signal transmission quality. Increase the loss of transformers and lines. Dynamic reactive power compensation devices (SVG) can perfectly solve these power quality problems.

Recently, the oil field has actively promoted green development and low carbon, increased the introduction and transformation of power, significantly increased the scale of grid-connected drilling rigs, and gradually improved construction results, promoting clean production and green development. From 2018 to 2023, the participation of oilfield grid-connected electricity increased from 24.56% to 62.26%, showing a continuous growth trend. The target for the utilization rate of onshore grid-connected electricity in the east in 2024 is no less than 80%, the goal is 90%, and strive to achieve breakthroughs in offshore grid-connected electricity facilities. However, most of the oilfield power grids were built in the 1970s and 1980s. Problems such as aging lines and excessive burdens have limited the widespread application of grid-connected drilling rigs. Some remote wells have power supply problems due to insufficient grid coverage and unstable voltage. The company-FGi has formulated an energy storage plan for this purpose. Through technologies such as fluctuating voltage fluctuations, reactive power compensation, and harmonic control, the stability of the grid is improved, effectively solving the pain points of electricity consumption in oil-to-electricity conversion. #FGI #ESS #OILFIELD
