What action can be taken to prevent voltage collapse due to a reactive power deficiency?

To prevent voltage collapse due to a reactive power deficiency, installing capacitors is a highly effective action. Capacitors provide reactive power support to the electrical system, which helps to maintain voltage levels. By supplying reactive power, capacitors can offset the reactive power demand from loads, thus stabilizing voltage and preventing collapse.

Reactive power is essential for the proper functioning of the power system because it supports the formation of electric and magnetic fields in alternating current equipment. When there is a lack of reactive power, voltages can drop, which may lead to a voltage collapse. Installing capacitors can help improve the voltage profile by increasing the available reactive power in the system.

Load addition would normally exacerbate the issue if there is already a reactive power deficiency, as it increases demand without adding any reactive power resources. Implementing load reduction may seem beneficial at first since it lowers demand, but it doesn’t directly address the need for reactive power, which can still lead to voltage stability issues. Lastly, increasing frequency is not a viable solution for addressing reactive power deficiencies, as it does not affect the levels of reactive power and can disrupt system operations. Hence, installing capacitors emerges as the most effective and relevant solution in this scenario.
