An Analysis Of Power Quality Improvement By Reactive Power Compensation Devices

Providing continuous high-quality power is an important aspect of a power system. This, however, requires the use of compensation devices due to the nonlinear load condition and dynamic nature of the power system to avoid invalidating the legal limit standard set by a country’s supply regulation. Keeping the power and voltage level within the given statutory limit can be achieved by injecting or absorbing reactive power by using reactive power compensation (RPC) devices. Flexible AC Transmission Systems (FACTS) also play a key role in enhancing power quality. This paper discusses simulation models developed in IPSA and ETAP software to simulate the power quality improvement of a selection of devices and conducts a performance analysis.
