Q & A

What is the main complexity of electrical power systems?

Electrical power systems are complex due to their extensive geographical coverage, the need for synchronization among hundreds of generators, and the integration of thousands of kilometers of transmission lines.

What is the primary goal of developing electrical power grids?

The primary goal of developing electrical power grids is to generate, transmit, and distribute power to customers reliably, stably, and uninterruptedly.

What is the role of compensators in an electrical power system?

Compensators, specifically reactive power compensators, play a crucial role in maintaining the efficient operation of the network by absorbing, generating, or applying reactive power where and when it is required.
