Oscillation Damping

The fault ride through capability and fast controller action makes doubly fed induction generator based wind energy conversion system to actively participate in power oscillation damping. This article describes a coordinated reactive power control from grid side converter along with active crowbar scheme for doubly fed induction generator which can actively participate in power oscillation damping, and thus improve the transient stability margin of entire power system. For a reactive power oscillation damping ( [Formula: see text] power oscillation damping), it is essential that the phase of the modulated output is tightly controlled to achieve a positive damping. Detailed 3 generator 9 bus Western System Coordinating Council system is modeled in PSCAD/EMTDC with the generator dynamics. The dynamics in power flows generator rotor speeds and voltages are analyzed followed by a three-phase fault in the power system. A set of comprehensive case studies are performed to verify the proposed control scheme.

The doubly-fed induction generator has significant features compared to the fixed speed wind turbine, which has popularised its application in power systems. Due to partial rated back-to-back converters in the doubly-fed induction generator, fault ride-through capability improvement is one of the important subjects in relation to new grid code requirements. To enhance the fault ride-through capability of the doubly-fed induction generator, many studies have been carried out. Fault current limiting devices are one of the techniques utilised to limit the current level and protect the switches, of the back-to-back converter, from over-current damage. In this paper, a review is carried out based on the fault current limiting characteristic of fault current limiting devices, utilised in the doubly-fed induction generator. Accordingly, fault current limiters and series dynamic braking resistors are mainly considered. Operation of all configurations, including their advantages and disadvantages, is explained. Impedance type and the location of the fault current limiting devices are two important factors, which significantly affect the behaviour of the doubly-fed induction generator in the fault condition. These two factors are studied by way of simulation, basically, and their effects on the key parameters of the doubly-fed induction generator are investigated. Finally, future works, in respect to the application of the fault current limiter for the improvement of the fault ride-through of the doubly-fed induction generator, have also been discussed in the conclusion section.
