Harmonic Assessments and Filter Design

The connection of large renewable energy generators to relatively weak networks, and associated strict harmonic emission limits for these projects has driven an increasing deployment of harmonic filters, and notably C-type filters in recent years.

The presentation briefly reviews other commonly used configurations and illustrates the key benefits of C-type filters as being reduced losses and excellent mitigation across a wide frequency range. A review of practical requirements of component ratings will be presented. Several variants of the filter will be presented in order to demonstrate protection requirements and options. The prospects of standardised filter designs in transmission and renewable applications will be discussed. Practical aspects of the filter will be presented in terms of switching transients and minimum requirements for reliable commissioning and operation.
