Designing Passive Harmonic Filter for Wind Farms



As part of grid code and design requirements any renewable energy power plant (solar, wind etc.) connecting to the public grid must comply with the harmonic limits set by the TSO. As a large number of projects are being connected with large cable networks, inter array cables (IAC) and/or long export cables (EXC) resonances in the IAC system or between the renewable energy power plant and the public gird might cause challenges which needs to be solved with passive harmonic filters.
Choosing, designing and tuning a passive harmonic filter is an iterative time-consuming process which could maybe be completely or partly automated to make it easier and faster to arrive at a good filter solution for a specific site/system.
