AI Customer ServicePumped storage hydropower plants fall into two categories: Pure (or closed-loop) pumped storage: in this type of plant, naturally flowing sources of water into the upper reservoir contribute less than 5% of the volume of water that passes through the turbines annually.
In the event of a power outage, a pumped storage plant can reactivate the grid by harnessing the energy produced by sending "emergency" water – which is kept in the upper reservoir for this very purpose – through the turbines. Pumped storage hydropower plants fall into two categories:
An interconnected system of pumped storage plants are more suitable, when the quantity of water available for power generation is insufficient in peak period and also highly suitable for areas of high dam construction. Pumped storage plant essentially consists of head water pond and a tail water pond.
Because pure pumped storage hydroelectric power plants essentially have no river water inflow into their upper adjustment reservoirs and generate power using water pumped up from their lower adjustment reservoirs only, they can be sited without the need to consider river system conditions as long as the heads are sufficiently large.
Operating modes of pumped storage plant: There are three types of operating cycles (i.e.,) Daily, weekly and yearly. Types of pumped storage plant: (i) Overground pumped storage plant (a) Overground pumped storage system with hydro-electric power plant The Fig.4.35 shows the overground pumped storage system.
Introduction – Pumped Storage Power Plant are generally used for peak loads. An interconnected system of pumped storage plants are more suitable, when the quantity of water available for power generation is insufficient in peak period and also highly suitable for areas of high dam construction.
