Off-grid voltage controller for micro hydro

This kind of off-grid control panel is very suitable for micro hydropower project in the Mountain area without electricity Grid, Mining areas, Vacation Villa, Temples, Farm, Community and all far away Location with water resources without electricity Grid, with competitive price and easy installation, we can offer you this kind of off-grid hydropower voltage control  panel and dump load system from 300w to 5kw.

Grid inverter for microhydro

• Main circuit is using U.S. TI’ DSP chip, Infineon IGBT modules,Infineon‘s driver protection, grid-connected output part adopts isolation transformer, safe and reliable ;
• Using SPWM pulse width modulation,pure sine wave output,automatically synchronized with the grid tracking,power factor close to 1.Low current harmonic content , pollution-free and non-shock to grid;
• Hydro input maximum power tracking technique (MPPT);
• grid-connected inverter’s current closed loop control, control and regulate;
• DC voltage across a wide range of input,adapt to different circumstances demand;
• Frequency disturbance the technical, to achieve control of anti-island;
• A comprehensive power to protect and improve yourself and protect the function.In case of system failure to stop the grid-connected invert ion ;
• Circuit frame compact, ax. Efficiency≥94%;
• Protection class up to IP20 ;
• Optional RS485 communication, Upper machine monitoring, achieve the remote data collection and monitoring ;

Grid control panel for hydropower

1. With main generator synch and protection circuit breaker.
2. With terminals to connect to the alternator power.
3. With terminals to connect to the governor.
4. With suitable protection to protect against incoming mains faults.
5. Generator protection functions (over current, over load, over voltage, low voltage, over-speed, low frequency and so on).
6. With suitable control functions to control the alternator excitation
7. With 4/20mA level input and control function to allow load adjustment dependent on water sensor.
8. With meters for Voltage, Current, Power, Frequency, excitation current.
9. With indication lamps for main circuit breaker status, faults and alarms.
10. With one button start, automatic excitation function, automatic storage function, automatic quasi synchronization function, automatic active power regulation function, automatic reactive power tracking function, automatic reducing power shutdown, automatic water level regulating operation function, automatically adjust the frequency and the power.

Because different hydro power project head and flow should choose different turbine and different size turbine runner to meet, Turbine specification table can not show all the detail to meet all kind of condition of customer’s project situation, here table only for reference, so please give me your Head and Flow,  together with your requirement, we will make the  suitable design to meet your need, thanks.
