Interface circuit analysis of wind-induced vibration power generation

The control of SECE interface circuit is simpler than SCEI, and the SECE interface circuit is more suitable for wind-induced vibration power generation with piezoelectric

Design and Modeling of Hybrid Power Generation

The results have shown the battery working states in the real hybrid solar–wind power generation system. The control circuit is realized by using a digital signal processor and auxiliary

Modeling, Simulation and Control of a Doubly-Fed Induction Generator

This paper presents a simulation study of a wind power system based on the six-phase SCIG generator with a rated power of 149.2 kW. The grid part is controlled by a three

Introduction to Doubly-Fed Induction Generator for Wind Power

An AC-DC-AC converter is included in the induction generator rotor circuit. The power electronic converters need only be rated to ha ndle a fraction of the total power the rotor power typically

Interface circuit analysis of wind-induced vibration power generation

Both SECE and SCEI performed stable output power over a large load range, while the remaining three interface circuits are somewhat deficient in output power or stability.

IET Generation, Transmission & Distribution

With the conventional LVRT control method based on crowbar circuit, as shown in Fig. 4, the electrical power of the PMSG (P s) remains constant when the grid fault happens, as the GSC cannot deliver all the

6 FAQs about [Control circuit of wind power generation]

What is the control system of a wind turbine?

The control system of a wind turbine is presented. Specifically, the supervisory control system and the power production control system are introduced. The power production control comprises of the generator torque control and the pitch control subsystems, the power electronics and the grid connection. Yaw control is also discussed.

How to control DFIG-based wind energy conversion systems?

This paper presents the comparative study of control techniques which are generally employed for doubly fed induction generator (DFIG)-based wind energy conversion systems (WECS). Vector control, direct torque control and direct power control schemes are mostly employed to control DFIG-based WECS.

What is the control strategy used in a wind turbine?

The control strategy used in this wind turbine can be summarised as follows: Power optimization strategy: In this case, the wind is not high enough to produce the rated power so that the speed controller acts on the pitch angle in order to achieve the optimal rotational speed, and thus maximizing the power extracted from the wind.

Which controllers are used in small wind energy conversion systems?

The conventional controllers are the most commonly used in small wind energy conversion systems. These usually consists of a PID/PI controller for rotor speed and generated power control. These controllers are more suitable for small WT systems.

What is the electrical subsystem of a wind turbine?

The preset Chapter presents the electrical subsystem of a wind turbine. Specifically, the power control, the electrical generator, the power electronics, the grid connection and the lightning protection modules are discussed. The content is targeted to contemporary megawatt (MW) wind turbines. The control system of a wind turbine is presented.

What are the mechanical systems of a wind turbine?

Section 4 describes the modelling and control of the mechanical system of a wind turbine, which is composed of the following systems: aerodynamic rotor, drive train, and blade pitch angle control.
