What is the main purpose of reactive power compensation in distribution systems?

The main purpose of reactive power compensation in distribution systems is to provide reactive power and improve the power factor. In electrical systems, especially in AC power systems, power can be categorized into two types: real power, which effectively performs work, and reactive power, which does not do any useful work but is necessary for maintaining the voltage levels needed to effectively deliver real power.

By compensating for reactive power, distribution systems can enhance operational efficiency, reduce losses, and maintain equipment stability. Improved power factor means that the system is using electricity more effectively, which can lead to reduced demand charges and better overall performance of the electrical network. Therefore, reactive power compensation is crucial for ensuring that power systems operate reliably and efficiently while minimizing the risk of voltage instability and reducing waste in energy utilization.

This crucial understanding of reactive power's role in maintaining system performance and stability positions reactive power compensation as a vital process in electrical distribution systems.
