http://www.parker.com/gridtie - As countries across the globe continue their migration to more renewable energy sources on larger and larger scales, the technology needed to effectively use these energy sources has been rapidly developing. Grid tie technology enables various energy sources to feed the power grid. While this sounds like a simple concept, the energy produced by renewable power generation sources is typically not compatible with the grid, and one or more stages of conversion and synchronization are required. That is where the grid tie inverter comes into play.
The grid tie inverter accepts energy from a variety of sources and converts it to a form that can be efficiently fed to the power grid. Different configurations of grid tie inverters are available for different applications.
PV solar fields, for example, produce direct current (DC), which is changed to alternating current (AC) for compatibility with the grid.
Grid tie inverters used in battery energy storage are similar, but since they must both charge and discharge the battery banks, they must be a "bidirectional" design.
Grid tie inverters may include special features for different applications like wind turbines. For example, many include "anti islanding," an automatic controlled disconnect when the grid is lost due to a blackout or other fault.
Common power platform simplifies
Parker’s development of a wide range of grid tie inverters and related systems creates a common power platform. With over three decades of experience in power conversion, this common power platform is employed in inverters across applications such as solar power, energy storage, and wave power. A range of enclosure configurations is provided, from rack style to mobile hardened to direct outdoor mounting, depending on the application and environmental conditions. A modular design also provides ease of serviceability, which is important when equipment is located at a remote site. Equally important in a grid tie inverter design is an efficient and effective cooling system. Through Parker's experience in climate control, a unique two-phase liquid cooling system is available in megawatt class inverters.
The system is self-contained, and enables systems of very high power density to be installed in areas of limited space. Inverter sizes from kilowatts to multi-megawatt utility scale systems have been deployed in locations worldwide.
