Southeast Asia is an energy rich region with renewable resources. There is abundant sunshine, steady winds in coastal areas and fast flowing rivers, which are ideal for distributed power generation. Many such systems rely on the permanent magnet generator as their core component. Permanent magnet generators use strong rare earth magnets, making them more efficient and requiring less maintenance than traditional generators that need external excitation current.
The Small Capacity Generator for Home Wind Systems
A small PMG (500W – 2kW) is a great solution for small-scale wind generators such as those found in residential applications in tropical countries like the Philippines, Vietnam, and Thailand. They are ideal for complementing horizontal or vertical wind turbines in an off grid wind system. The low cogging torque makes it suitable to start the turbine even in light breezes, which is a very useful feature in moderately windy places. Humidity and dust protection is achieved with sealed enclosures for these generators, designed by DHC. Homeowners become self-sufficient in energy without the need for noisy fuel generators.
The Mid-Capacity Generator for Farm and Village Microgrids
Indonesia, Myanmar, and Cambodia have rural farms and village microgrids that need more robust power. The applications call for an intermediate size permanent magnet generator, between 3kW and 10kW. A larger horizontal wind turbine or hydro generator, such as the Turgo or axial flow water turbine, or a diesel engine fueled with biodiesel can all drive such a generator. The great advantage of the permanent magnet type is its versatility. It maintains stable voltage over a wide range of wind speeds, allowing it to be used in hybrid systems with varying wind and solar power sources. DHC provides vibration reducing generators with disc coreless technology, prolonging bearing life. These mid capacity units are the mainstay of many wind solar hybrid power systems for farming communities.
The High-Capacity Generator for Commercial and Industrial Use
Malaysia and Thailand's commercial operations like resorts, eco lodges and aquaculture farms have greater electricity requirements. High-capacity permanent magnet generator (15kW to 50kW) can be used for water pumps, cooling systems, processing equipment and guest facilities. In combination with an on grid wind system or a wind solar hybrid system, the wind power can also connect to the local utility grid with feed-in tariffs. DHC builds larger generators with high temperature magnets that do not demagnetize under heavy load, along with reinforced frames. Even for large generators we have a professional supply chain management to ensure that products are delivered on time from Southeast Asia. Many generators can be synchronized for even greater power.
The Hydro-Specific Generator for River and Stream Projects
There are thousands of rivers and irrigation canals in Southeast Asia suitable for small hydropower. A permanent magnet generator optimized for hydro applications-including Turgo, axial flow, and mixed flow water turbines-offers excellent efficiency. Water flows all day long and is more consistent than wind. That constant mechanical energy is then converted by a hydro generator using permanent magnet technology into a steady source of electricity with minimal loss. These generators use lower rotational speeds than wind generators and thus special winding designs are required. DHC has created hydro generators that begin to producing power at low flow velocities and are suitable for small streams and agriculture runoff canals. These systems can be used in remote villages for schools, clinics and water purification systems.
Conclusion
Choosing the right permanent magnet generator for your Southeast Asian application is dependent on the power needs, energy source and environmental conditions. Homes are best served by small generators. The mid size capacity units are designed for farms and villages. Commercial operation is powered by high capacity generators. Hydro-specific designs extract energy from rivers and canals. Jiangsu DHC Environmental Si-Tech Co., Ltd has been engaged in the field of Green Environment Protection since 2009.
