Open-Loop Two-Generator System with Midpoint Voltage Compensation Using FC-TCR Configuration

This document presents a simulation model of a two-generator system featuring midpoint voltage compensation using an open-loop FC-TCR configuration with thyristor-controlled reactor (TCR) firing in open-loop mode. The model implements voltage compensation algorithms that reduce the midpoint voltage to nearly 1 p.u., achieved through precise control of thyristor firing angles and reactive power balancing between the fixed capacitor and thyristor-controlled reactor branches. The simulation includes key components such as thyristor switching logic, firing angle calculation blocks, and power measurement modules that monitor system parameters in real-time. This implementation provides significant insights into Static Var Compensator (SVC) operation and serves as a foundation for designing closed-loop compensation control systems. Power system engineers can utilize this model to study system behavior under varying operational conditions, including load changes and fault scenarios, through parameterizable simulation blocks. The model incorporates adaptive control algorithms that adjust reactive power injection based on voltage deviation measurements, enabling analysis of transient stability and voltage regulation performance. The simulation framework allows for testing different control strategies through customizable function blocks and script-based controllers, facilitating the development of efficient and reliable power systems. By employing this model, engineers can enhance their expertise in power system analysis, control design, and compensation technique implementation, contributing to solutions for contemporary energy challenges. The code structure includes modular components for easy integration with additional control systems and scalability for multi-machine power system studies.
