6 FAQs about [Energy storage power supply for mine hoisting system]
What is a power supply for a mining operation?
The concept of power supply for a mining operation, therefore, is one which provides for a reliable supply to the main distribution point in a mine, from which power is then distributed to all the key loads in the operation.
What is the power demand of a mine hoist?
The power demand of a mine hoist varies over the hoisting cycle from zero during loading and un-loading to about 200% of the rated motor power at the end of acceleration. In addition, the power demand change rate, dP/dt [MW/sec] is often high during the hoisting cycle.
Can flywheel energy storage be used in mine hoist applications?
Flywheel energy storage in mine hoist applications is by no means a new thing. It has been successfully used in Ward-Leonard- Ilgner systems in which the flywheel is mounted to the shaft of the DC generator that powers the DC hoist motor.
How does energy storage work?
Using an energy storage system that delivers energy corresponding to the power demand of the hoist above a certain value and that recharges when the power demand is low reduces both the peak power demand from the network, power change rate and the power swing during the hoisting cycle.
Why is a mine hoist the worst load on the power network?
ABSTRACT: A mine hoist is probably the worst load on the power network of a mine due to its frequently changing power demand. During every hoisting cycle lasting for about 1.5 to 3 minutes, the power demand changes many times, often at high change rate. The load variations cause severe disturbances on the network in the form of voltage variations.
Why does mine electrical equipment need a separate Supply Substation?
Mine electrical equipment is characterized by abruptly variable loads with high starting currents. That is why a separate supply substation with equipment for power compensation, which is connected with the main transmission line, . * Corresponding author.
