1. Technical Field
The invention belongs to the technical field of pumped storage power station, and
particularly relates to a pumped storage power station in which underground cavern cooperate
with ship lock.
2. Background Art
The pumped storage power station is a hydropower station that uses the low power of
the power load to pump the water from the lower reservoir of the pumped storage power
station to the upper reservoir of the pumped storage power station, and then puts the water
stored in the upper reservoir to the lower reservoir to generate electricity during the peak
power load. Pumped storage power station. Pumped storage power stations can effectively
adjust the structural adjustment requirements of wind power, photovoltaic power generation,
thermal power generation, and nuclear power generation. my country has built a large
number of pumped storage power stations such as upper and lower reservoir pumped storage
power stations, island pumped storage power stations, and the world's largest pumped storage
power station. Energy-storage power stations and pumped-storage power stations have
become one of the main clean energy sources that are indispensable for my country's electric
power development, and there is an ever-expanding market demand.
The problems existing in the existing pumped storage power stations are relatively small
storage capacity and insufficient utilization of underground land resources. In order to solve
the above technical problems, the inventor proposes a pumped storage power station in which
underground cavern cooperate with ship lock.
