The utility model provides a mixed wind-light compensation
water pumping and energy storing
system comprising a wind-light compensation unit, a controller, a
direct current load, an
alternating current load, an
inverter and a
water pumping and energy storing unit. The wind-light compensation unit comprises a wind generating set and a photovoltaic array; the
water pumping and energy storing unit comprises reversible water pump-
water wheel unit, an upper water pond and a lower water pond; and the controller comprises a wind-light compensation controller, a
digital signal processor
chip, a
voltage / current sampling circuit, a
voltage /
current transformer set, a breaker
driving circuit and three breakers. In the invention, a traditional wind-light compensation
system, namely an energy storing device-storage battery set, is replaced by a pumped storage and
power generation system, on the water pumping and energy storing unit, the reversible water pump-
water wheel unit is used for pumping water or generating
electricity, and by applying a segmented integration method, the energy of the upper water pond of the water pumping and energy storing unit is monitored and controlled. With the mixed wind-light compensation water pumping and energy storing
system, the defects of expensiveness, short service life, environmental
pollution and the like of a storage battery set can be solved, the
system stability and power supply reliability can be improved, and the
system building and running cost can be lowered.
