Based on Hamiltonian energy theory, this paper proposes a robust nonlinear controller for the wind turbine with doubly fed induction generator （DFIG）, such that the closed-loop system can achieve its stability. Furthermore, in the presence of disturbances, the closed-loop system is finite-gain L2 stable by the Hamiltonian controller. The Hamiltonian energy approach provides us a physical insight and gives a new way to the controller design. The simulation results illustrate that the proposed method is effective and has its advantage.

Test-Bed of doubly fed induction generator for Variable-Speed Constant-Frequency Wind Power Generation

2011 International Conference on Advanced Power System Automation and Protection(APAP 2011)

Against the backdrops that the large-scale DFIG-based wind generations are accessed to grid and requested to maintain grid-connected operation during faults, the short-circuit current contributed by the generation has become an unavoidable problem. However, the traditional calculation methods aimed at synchronous generator cannot apply to the grid contained the increasing DFIG-based wind generations. A new calculation method is urgently needed to solve the short-circuit current required by the planning, protection and control of the power grid. In the present paper, the transitions of DFIG under symmetrical and asymmetric short-circuit condition are mathematically deduced and the short-circuit characteristics of DFIG are analyzed. A controlled source is proposed to model DFIG during grid faults based on the derived expressions. Meanwhile, the equivalent circuit and the sequence networks of a single-machine infinite bus system is built to calculate the steady-state short-circuit current. The time-domain simulations are conducted to verify the accuracy of the proposed method.

Robust Nonlinear Control of Wind Turbine with doubly fed induction generator by Using Hamiltonian Energy Approach

＜正＞In this paper, a test-bed built for the experiments of variable-speed constant-frequency （VSCF） wind power generation is described. The test-bed is composed of a doubly fed induction generator （DFIG）, a VVVF inverter driven squirrel motor for wind turbine simulation, dual-DSP-based controllers, as well as a PC-based data-acquisition and control system. In this system, a pair of bidirectional PWM voltage-source converters in a back-to-back configuration is inserted between the rotor windings and the grid lines to control the rotor currents in order to vary the slip power thereby implementing the VSCF operation. Vector-control is used to independently control the flow of active and reactive power between the system and grid line, and to make it easy for the system to implement maximal power point tracking （MPPT） and optimal reactive power splitting in wind power plants.
