Power Hardware in-the-Loop Validation of DC-DC Power Converter

Power Hardware in-the-Loop Validation of DC-DC Power Converter

The paper describes the development of a power converter small-scale mock-up and a real-time model of an offshore wind farm. Power Hardware In-the-Loop (PHIL) validation is proposed for a demonstration of grid architecture and control principles. Results obtained with a test bench underline the importance of PHIL testing in the power converter development for DC grid applications.

An Intelligent Controller based Power Grid Interconnected System for Reliable Operation

An Intelligent Controller based Power Grid Interconnected System for Reliable Operation

The main objective of the research presented is to control the unidirectional boost converter (UBC) by implementing an intelligent controller (IC). The IC continuously captures power conversion based on power output data from wind and solar energy. Then, it injects gate pulses into a power electronic switch based on the data value. The overall design and simulations are performed using MATLAB/SIMULINK.

Phase-Exact Adaptive Feedforward Control Modulated Gear Mesh Vibration at 4.7 kHz

Phase-Exact Adaptive Feedforward Control Modulated Gear Mesh Vibration at 4.7 kHz

This paper proposes a setup for active vibration control to suppress transmission of gear mesh vibration to the surrounding structure using piezoelectric inertial mass actuators. The proposed control algorithm uses multiple adaptive feedforward controllers. To achieve the desired sampling frequency in real-time several optimizations are introduced.

Design and Implementation of Bi-Directional DC-DC Converter for Wind Energy System

Design and Implementation of Bi-Directional DC-DC Converter for Wind Energy System

This paper features designing and implementing a bi-directional DC-DC converter with a Speedgoat controller for wind energy conversion systems. An energy storage device is used to compensate for the fluctuations and to maintain a smooth and continuous power flow in all operating modes to load. The complete system is implemented in MATLAB/SIMULINK and verified with hardware.

Fault Diagnosis of Star-Connected Auto-Transformer-Based 24-Pulse Rectifier

Fault Diagnosis of Star-Connected Auto-Transformer-Based 24-Pulse Rectifier

The authors propose a fault diagnosis method for star-connected auto-transformer-based 24-pulse rectifier unit (ATRU) by integrating artificial neural networks (ANN) with wavelet packet decomposition (WPD) and principal component analysis (PCA). First, the fault features are extracted and simulated in a real-time simulation platform. The obtained data is then analyzed with MATLAB toolboxes and verified with a digital signal processor.
