ABSTRACT

The rising influence of the operation and control of wind energy on power systems has entailed grid integration as a key concern. Therefore, different countries are opting different approaches in setting up new grid codes in addressing this issue. Fault ride through (FRT) capability in wind turbines is established to maintain transient stability, which requires the wind generators to sustain the operation of the turbines during fault without tripping. The grid code specifications for FRT capability and the operation of FRT in different types of wind turbines are discussed in detail in this chapter. The hardware-based solutions available to provide FRT capability such as crowbar, DC-link chopper, static compensator, dynamic voltage restorer, magnetic energy recovery switch, energy storage systems, series grid side converter, fault current limiter are discussed in detail in this chapter.
