Work principle and features
Working principle
: Wind energy is used as the motive power to provide low speed rotation of a permanent magnet generator to produce alternating current which is then converted to direct current by a controlled constant voltage rectification system, the resulting voltage being stored in a battery, or batteries. The direct current from the battery, (batteries), is then converted to alternating current by an inverter, the resulting controlled and stabilized alternating current being used to power the load, this is the general principle for battery storage type systems. Grid connect systems take the alternating current produced by the turbine directly to an inverter which controls and stabilizes the alternating current and also provides numerous control elements for direct connection to the electricity grid.
Features
: The products combine unique and innovative design with high reliability. The innovative design has been awarded both Invention and Practical new patents by the State Intellectual Property Department and thereby has totally independent property rights in China, resulting in the market leading position in wind to electrical energy conversion, technical design and efficiency. Key design features such as very low rotation speed result in increased efficiency in comparison to other small turbine systems.
Make use of ranges and application
The products are used in areas that benefit from good wind regimes but have little or no electrical grid connection such as; islands, desert and low inhabitation areas, frontier defense posts, microwave and telephone communication stations, forest observation posts, oil pipeline delivery stations, highway lighting etc. Rural and urban applications include, community squares and recreational areas, parks, landscape and scenic locations, resorts, and other ecological areas, applications also include on or off grid national electrified fencing systems. The utilization of wind energy at no on-going cost significantly reduces the environmental impact of fossil fuel usage whilst saving vital energy resources
