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.

Flexible configurations

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.

    • Making the Most of Renewable Energy
    • What is “Grid Tie”? • In very basic terms, the concept of “Grid Tie” refers to a connection to the power grid, used to FEED power as opposed to CONSUMING it. Solar Wave Wind Battery Generating Utilities
    • Sounds simple? • Not really…Unless the generating source matches the grid frequency and is synchronized with the generating utilities, a connection will not be successful… Variable AC Variable DC Variable DC Variable AC 60 Hertz AC Generating Utilities – 60 Hertz AC
    • Enter the Grid Tie Inverter… Grid Tie Inverter System • A Grid Tie Inverter system converts generated or stored power to a form that is compatible with the power grid
    • What is a Grid Tie Inverter? • An electric power conversion device used to convert raw generated power in various forms into regulated AC and feed it into the utility grid in a synchronized and controlled manner. Active Bridge InverterLCL Filter POWER FLOW POWER FLOW Active BridgeLCL Filter POWER FLOW POWER FLOW Grid-Tie inverter for generated AC Grid-Tie inverter for generated DC or battery supply Variable AC 60 Hz AC DC 60 Hz AC
    • What is a Grid Tie Inverter? • Applications producing generated AC use two power sections – one to convert the generated AC into DC, and the second to invert the DC back to 50 or 60 Hz AC and feed it into the grid. • The technical name for a grid tie inverter is "grid-interactive inverter". They may also be called synchronous inverters or Active Front End units. • Grid tie inverters incorporate a circuit to detect and lock in on the phase angle of the grid power before energizing. • Some grid tie applications have special requirements like “anti- islanding”, designed to take the unit off line in the event of grid failure, or specific electrical codes like UL1741.
    • Some Grid Tie Inverter applications Wind turbines Photovoltaic solar fields Wave power Energy storage
    • Parker Energy Grid Tie Division Products and Systems Offered • Outdoor duty central inverters for PV solar • Modular grid tie inverters for wind power generation • Marine hardened inverters for wave power • Bidirectional inverters for battery energy storage PCS (power conversion systems) • Battery Energy Storage Systems
    • • The basis of most grid tie systems is Parker’s modular “890” inverter design • The grid tie inverter can combined with other components and packaged to form a complete system, relevant to the application Parker 890 Series Grid Tie Inverter
    • Parker Modular Flexibility • Field replaceable IGBT phase modules • Modular inverters can operate in parallel for highest power ratings AC890PX Grid Tie Inverter Easy plug-in replacement!
    • Cool under pressure • Air cooled ratings use efficient plenum design to maximize cooling while keeping airborne contaminants away from electronics • Parker Advanced Cooled ratings allow higher power in smaller footprint • Safe dielectric coolant in hermetically sealed system requires no routine maintenance AC890PX Grid Tie Inverter Advanced cooled 1.5 Megawatt inverter
