Reactive Power Compensation Device Switching Under Three-Phase Unbalanced Conditions

This is my self-developed simulation for reactive power compensation device switching under three-phase unbalanced conditions. The implementation incorporates 8421 encoding and zero-crossing detection with zero-point switching functionality.

In this simulation, I utilized 8421 encoding and zero-crossing detection techniques to achieve reactive power compensation device switching during three-phase imbalance. Through the application of 8421 encoding, I implemented encoding and decoding of three-phase currents, enabling automatic engagement and disengagement of the compensation device. The algorithm involves mapping current values to binary codes for precise device control. Simultaneously, the zero-crossing detection technology allows switching operations at the exact moment when current waveforms pass through zero points, ensuring accurate timing for compensation device activation. This is implemented through real-time waveform monitoring and threshold-based detection algorithms.

This simulation project not only models reactive power compensation device switching under three-phase unbalanced conditions but also serves as an application and verification platform for 8421 encoding and zero-crossing detection technologies. Through this project, I gained deeper understanding and mastery of the underlying principles and practical applications of these techniques, including their implementation in power electronics control systems.

Additionally, this simulation considers other critical factors such as device stability and reliability. Through multiple simulation experiments and parameter adjustments using PID control algorithms and stability analysis methods, I ensured that the reactive power compensation device operates correctly under various working conditions and performs timely, accurate compensation operations. The system includes fault tolerance mechanisms and adaptive control logic.

Overall, this simulation project represents more than just a simple device switching model; it constitutes a comprehensive system that integrates multiple technologies and considerations. Through this project, I enhanced my technical capabilities and provided robust support and validation for practical applications in power quality management systems. The code architecture includes modular design for easy scalability and maintenance.
