Static Var Compressor (SVC) Component

Detailed Documentation

The Static Var Compressor (SVC) is a critical device in power systems for dynamically regulating reactive power, with its core functionality focused on maintaining system voltage stability and improving power quality. The program introduced in this document implements an undamped control-based SVC function, adopting a modular design philosophy that facilitates functional expansion and maintenance.

The program is primarily divided into the following modules: Signal Acquisition Module: Responsible for real-time detection of grid voltage and current signals, providing data support for subsequent reactive power compensation calculations. This module typically involves ADC (Analog-to-Digital Converter) interfacing and signal conditioning algorithms. Reactive Power Calculation Module: Based on the acquired voltage and current signals, this module computes the system's reactive power requirements and determines compensation strategies. Implementation often involves power theory algorithms like pq theory or Fourier analysis for harmonic extraction. Control Logic Module: Utilizing an undamped control algorithm, this module rapidly responds to system changes by adjusting the firing angles of thyristors or TSC/TCR (Thyristor-Switched Capacitor/Thyristor-Controlled Reactor) to achieve dynamic compensation. The control logic may incorporate PID controllers or advanced fuzzy logic for precision tuning. Communication Interface Module: Supports data exchange with upper-level computers or other power automation devices, enabling monitoring and control functions. This module commonly implements protocols like Modbus TCP/IP or IEC 61850 for industrial communication standards.

This modular design not only enhances code readability and reusability but also allows the program to flexibly adapt to power system applications of different scales. The undamped control strategy effectively reduces system oscillations and improves compensation response speed, making it suitable for scenarios with frequent dynamic load variations. The code architecture employs object-oriented programming principles, with each module encapsulated as independent classes containing well-defined interfaces for seamless integration.
