Small scale wind power

Small industrial rooftop power stations are often recommended to use a string inverter connection scheme, with an installed capacity generally between 500-6000KW. The orientation of the photovoltaic modules is not consistent, and there are local obstructions. They can be connected to a 10V voltage level power grid.

System Network Structure

feature

(1) High reliability distributed wind power generation system can be used in all weather conditions: high-altitude areas in winter, high humidity areas in rainy season, coastal salt spray areas, high-altitude areas, desert and Gobi areas. Multiple wind turbines can operate independently without interfering with each other;

(2) High safety is a prominent feature of electrically controlled wind turbines. Electronic control technology is an intelligent safety protection system that can achieve maximum speed and constant maximum voltage. The overspeed, overvoltage, and overspeed protection functions ensure the safe operation of the entire unit;

(3) Efficient high power grid connection, low requirements on the grid side, systematic design, complete set design of units/control/inverter, integrated as a whole, all parameters involve every link of power generation, fully ensuring the safe and efficient operation of units, high utilization rate, and ensuring that wind resources are input into the grid at maximum efficiency;

(4) High profit electrically controlled wind turbines have good low wind speed starting characteristics, low rated wind speed, and higher power generation. They can sustainably and stably generate electricity in the wind speed range of 11-25m/s, with high reliability and an annual cumulative power generation that is more than 30% higher than ordinary wind turbines;

(5) The highly intelligent integrated system is equipped with monitoring devices that can remotely monitor the operating status of each wind turbine, diagnose faults remotely, reset remotely, and analyze data;

Recommended on-site hardware configuration

(1) The external rotor rare earth permanent magnet generator with special stator design has a higher conversion efficiency than the same series or product;

(2) A dedicated wind turbine with auxiliary kinetic energy has been added to the central area, reducing the starting wind speed and improving the wind energy conversion rate;

(3) The connection with the tower uses national standard flanges for easy installation of the tower;

(4) The external wind turbine blades adopt optimized aerodynamic shape design and structural design technology, with an integrated aluminum alloy profile or alloy steel material skeleton, covered with high-quality aluminum alloy sheet, high strength, light weight, and later subjected to high-temperature baking paint treatment, with better salt corrosion resistance;

(5) The generator casing is made of alloy steel material, combined with customized bearing rotors, which can not only withstand multi-faceted axial loads, but also have a load capacity nearly twice that of ordinary bearings; Low wind noise, low failure rate, stronger typhoon resistance, safe and reliable operation;

(6) Adopting intelligent tracking technology for wind power generation efficiency, effectively regulating current and voltage, and achieving high power conversion rate;
