Micro Hydro Control & Automation

In this day and age of data generation and tracking, it can be beneficial to have an understanding of how your microhydro system is performing.

These systems perform several key functions with regard to your microhydro system.

  • For a standalone system, a controller can keep the motor fully loaded by turning on and off a series of ballast loads.  The loads are rapidly switched on and off to maintain the proper turbine rpm and output voltage and/or frequency. This only applies for larger (~3kW and up) direct AC systems. Most small stand alone systems are controlled by their connection to a battery bank which evens out supply and demand and helps regulate turbine speed.
  • For grid connected systems to prevent the system from islanding.  This is a critical function that has requirements set by the utility you are connecting to.  It prevents your system from putting electricy on a grid that is supposed to be down for utility workers to safely work on the lines.
  • Another great thing a controller can do is to monitor intake water level (head).  This is accomplished by keeping the pipe full by opening and closing nozzles via electrically controlled ball valves or and electric actuated spear valves.
  • Last but not least is a control system can monitor system statistics.  Providing a dashboard of information to display, voltage, hz, RPM etc… depending on the setup and remote access capabilities may also be included.

We can work with our controller manufacturer and help determine a system that would work for you or you can work with them directly.

Micro Hydro Electric is a great company that builds their own controllers and can pull together all the sensors and controllers at very reasonable prices.  They provide excellent support and customer service.
