1.Background

As the aftermarket of offshore wind power generation, offshore wind power operation industry has great potential for development, at the end of the 14th Five-Year Plan, China's offshore wind power operation market size is expected to reach 11 billion yuan/year, at the end of the 15th Five-Year Plan will enter the peak of operation, the market size is expected to exceed 24 billion yuan.

The variable pitch backup system is a key functional component in the wind power generation system, which can provide power for it in a short time when it encounters an emergency such as a sudden power outage, so that it can quickly run downstream, so as to ensure the safe and reliable operation of the fan.

In order to better match with the wind farm, improve safety and reduce operating costs, FGI relies on the company's advantages in energy storage emergency power supply, according to the needs of customers, developed a set of low-voltage energy storage backup system suitable for wind turbines, and recently obtained the European CE certification, passed the strict high, low temperature, vibration testing, to meet the requirements of sea transportation. And exported to Southeast Asia.

2. FGI Solutions

FGIFP300 series low voltage energy storage backup system, is a set of "high efficiency, high safety, long life" as one of the intelligent backup power control system. The system adopts the design idea of "All In One", integrating battery PACK, BMS, PCS, fire protection system, etc., to form a standard, plug-and-play cabinet equipment.

Cabinet machine is simple to operate, one is a complete system, can work alone, immediately put into use after power, and easy to install. When the wind turbine is in the limit wind speed, when the power grid is cut off, the 400 V plant power connected to the fan enters the line, and the standby power is sufficient, which can ensure the working power supply of the fan load for at least 6 hours.

 3. product formation

This project proposes a new type of low-voltage energy storage backup equipment, which has 8 core modules and can maintain stable and reliable working characteristics in multiple occasions and multiple environments. The core systems are listed below:

Fire safety system
To provide effective means for fire safety;
Two-way converter system
Two-way current conversion between the DC side of the battery and the AC side of the grid;

4.Scheme advantage

Modular, standardized design scheme, a single outdoor cabinet covers a small area, convenient transportation and installation, installation site adaptation is high;
The AC side parallel scheme is adopted to fundamentally eliminate the circulation between battery clusters and further improve battery life;
