Direct-Drive Wind Permanent Magnet Generators

By |May 31st, 2013|

Investigation shows increasing demand for wind generators with large output power used for hybrid generators in remote areas. There is a growing demand in remote areas for small to medium rating (till 20 kW) wind generators for the stand-alone generation-battery systems. The type of generator required for the purpose must be light and compact so […]

Permanent Magnet Generator (PMG) Exciter

By |May 11th, 2013|

The Permanent Magnet Generator supplies more power than others for starting motor functions. The generator performs to sustain main field excitation for coordination and short circuit fault discrimination, and so provides greater immunity from loads of non-linear format.

In application, the PMG alternator features as a brushless exciter for first load response. The power control devices […]

Hybrid Electric Power Vehicle

By |May 9th, 2013|

With the replacement of mechanical transmission with electric motors, the needed amount of power is provided. This lowers fuel consumption by correct synchronization of the generator set power with the electric driven motors.

The most successful method is provided by a permanent magnet generator (PMG). The engine powers the generator which then powers the electric […]

India Wind Permanent Magnet Generators

By |December 9th, 2012|

India is on the path of fast economic growth. The most important factor involved in any growth story is the availability of uninterrupted power at a reasonable cost. Looking at the present scenario the picture does not seem to be very glossy. There being a considerable gap between the demand and supply position particularly during […]

Hybrid Technology: Save Power Generation Cost

By |October 19th, 2012|

Donauer Al Badi Gulf is a joint venture between Germany’s Donauer and NAS International. Their latest technology is based on a hybrid solution for power generation. A state of art solution including solar based panels is developed for commercial use in Middle Eastern countries.

Due to shortage of electricity during summers, the dependency on diesel […]

Here are some new technologies developed by big brand names in the field of marine energy development.
Albatern: WaveNET technology
Based on the technology of modules and associated nodes, this project has been granted 617,000 pounds under the WATERS2 scheme. With a development and testing phase in the period of late 2012 to late 2013, this project […]

Development in Wave Energy Technology – I

By |October 17th, 2012|

The marine energy industry has been in a state of technological developments recently. The efforts of many companies are being rewarded by various Government organizations which provide financial aid to boost research so that the industry keeps developing forward.

The most recent announcement was made by the Scottish Government which said that a funding of […]

Understanding Permanent Magnet Alternator

By |October 11th, 2012|

The output voltage of a permanent magnet alternator depends on the shaft rpm and the load. The higher the rpm, the higher is the voltage. The higher the load for a given rpm, the lower is the voltage.
Connection to Current and RPM o Load
The current (“amperage”) of a dc generator at any rpm is not […]

Wind PMG: Battery Charging Application – II

By |October 8th, 2012|

In marine environments where the sources of electricity are scarce, batteries are the only viable option and due to high wind speed at sea, these wind turbine battery charging options become a very profitable and convenient source. The overall cost of electricity is reduced. Also with battery usage the overall capacity of the site is […]

Wind PMG: Battery Charging Application – I

By |September 24th, 2012|

The market for small wind turbines is providing added electrification needed in remote areas. Many parts of the world are still running on electricity from batteries rather than electrical grids laid by national power corporations. Telecom companies who have to provide uninterrupted signals in remote areas rely on batteries and generators to get electricity. Another […]
