Unified approach to power quality mitigation

A unified approach to the compensation of multiple power quality phenomenon is described in this paper. It is shown that the converter-based power quality mitigation device is a viable solution to power quality problems on power networks since more than one power quality problem can be compensated by the same hardware. These devices should be capable of harmonic compensation or isolation, improving dynamic voltage regulation and flicker simultaneously, while capable of controlling power factor and power flow through the network. These functions can also be implemented independently. These power quality mitigating devices can be hybrid devices comprising passive components and converters. The drive is to minimize the converter power rating while maximizing the compensating performance. Several projects where this approach has been implemented are discussed in this paper.
