No Pollution Renewable Energy Permanent Magnet AC Alternator Radial flux Permanent magnet synchronous generator (PMSG)
The permanent magnet synchronous generator is a device that
transforms mechanical energy into electrical energy delivered by
the prime mover of the generator.
In a permanent magnet synchronous generator, there is no need for
the slip rings and carbon brushes, which makes the machine less
expensive, and lightweight, and maintenance of the generator also
decreases.
· Easy mechanical interface
Permanent magnet generators are widely adopted by the wind power
industry. Because there are no wearing parts, PMGs ensure low
failure rates and require less maintenance. The use of permanent
magnets requires no external power source to initiate a magnetic
field. This reduces costs, simplifies the structure, and improves
system efficiency. Applications of permanent magnet generators:>>· Low-speed, direct-drive PMGs operate without any gearbox and
fast-rotating parts, resulting in increased reliability and
superior drive train efficiency. · Generator can be designed with a segmented stator construction.
This provides redundancy and makes it possible to repair the
generator in the nacelle without full disassembly. Optionally, our
generator design can use the generator bearing as a turbine main
bearing to integrate the turbine brake system into the generator
construction. Benefits are simplicity, fewer components, and
therefore, higher reliability. · With the rising cost of electricity, an increasing number of
populations are looking for an alternate source of energy and
permanent magnet generators fit this gap perfectly. These
generators can also reduce the strain on the environment as they do
not use any non-renewable sources of energy for producing
electricity. Benefits of Permanent Magnet Generators Over Induction Generators:1. Free Energy Source
The wind generator uses NdFeB permanent magnets, eliminating the need for brushes and slip rings, reducing maintenance and improving reliability; the rated speed of the generator is low, and it is directly coupled and driven by the wind wheel, which simplifies the structure of the generator. The weight of the device is reduced, and the cost is reduced; The efficiency of the generator is higher, the starting resistance torque is small, and it is easy to start at lower wind speeds, which improves the low-speed power generation performance of the wind generator and improves the utilization of wind energy.
The importance of maintaining permanent magnet generator:
Wind turbines must be placed in the field, and the operating conditions are very harsh. In order to improve the reliability of wind turbines and prolong the service life of the wind turbines, routine maintenance is very important. When exchanging experience in wind power generation, foreign experienced experts once said that the focus of wind turbines is maintenance, not repair. The life span of wind turbines depends on the quality of maintenance. The maintenance of wind turbines is not complicated.
Operation and maintenance personnel must have basic knowledge of wind power technology and be able to work at heights in cold and hot weather. At the same time, the equipment maintenance personnel must have the ability to analyze and judge significant failures in person and the ability to handle them on-site and be able to quickly carry out minor repairs on the spot. Therefore, equipment maintenance personnel should be familiar with the structure of wind turbines and participate in operation and maintenance training courses during the installation process. The following maintenance measures are available for reference:
(1) According to the drawings, materials, and instructions provided by the manufacturer, prepare a detailed "Wind Power Operation and Maintenance Regulations" for relevant personnel to learn and implement carefully.
(2) Seriously study the basic principles of wind power generation, understand the performance of wind turbines and be proficient in starting and stopping methods.
(3) Regularly carry out ideological education to cultivate the sense of responsibility and professionalism of the staff.
(4) Accidents of generator sets should be carefully recorded, the reasons should be analyzed, and experience should be continuously accumulated.
The above points need your careful attention. If you still know more about wind turbines, please pay attention to the company website, we will update it regularly!
