Simulation and visualization method for loop control logic of controllable commutation converter valve

The controllable commutation converter valve is a new DC device that prevents commutation failure. Existing simulation methods focus on traditional or fully controlled valves, emphasizing functional verification and 2D displays that cannot intuitively show multi-state transitions or module coordination, limiting logic reasoning and response efficiency. To address this, this paper proposes a loop control behavior logic simulation and visualization method. Based on valve topology and operation rules, it defines state determination and action response algorithms for three operating conditions and realizes 3D visualization of signal paths, logic judgments, and action triggers. Results show that integrating logic simulation with graphical rendering enables tracing and visualization of control behaviors and state transitions, allowing early validation of strategy rationality and response performance, and promoting power equipment control from static rules to scenario-, event-, and state-based intuitive expression.
