Converters for pumped storage plants
Pumped storage plants are ideal partners for the expanding use of solar and wind energy. Storage plants provide load balancing to the network, ensuring the necessary parity between production and consumption. Therefore, when power is plentiful, water is pumped from a lower lake to replenish a higher reservoir, where it can remain stored for a long time. When power is needed, water is released, instantly turning turbines as the water falls to rapidly generate electricity.
ABB’s converter solutions for pumped storage plants increase the operational efficiency by improving the use of the stored water, mainly by gaining the possibility to provide energy balancing during pumping mode.
