Software zur Simulation eines elektrischen Wechselrichterantriebs und geschrieben in JavaFX (Software for simulation of electrical inverter drive and written in JavaFX)

First version

  • The software simulates an inverter-driven induction motor system, allowing users to configure motor parameters, control strategies, PWM settings, and thermal management.
  • It includes fault simulation, real-time data logging, and waveform visualization.
  • Generates three-phase voltages based on PWM signals, DC-link voltage, and modulation settings.
  • Includes harmonic injection and overmodulation options.
  • Models thermal dynamics with switching losses and cooling effects.
  • Replicates electromechanical behavior (speed, torque) using simplified torque calculations.
  • Models thermal effects based on resistive losses, fan speed, and coolant flow.
  • Supports different load types (Constant, Fan/Pump, Inertia).
  • Accounts for temperature-dependent resistance changes.
  • Implements V/f control with PI speed regulation.
  • Supports acceleration/deceleration limits.
  • Logs time, phase voltages ($V_a$, $V_b$, $V_c$), currents ($I_a$, $I_b$, $I_c$), speed, and torque to a CSV file.
  • Uses StringBuilder for efficient string concatenation.
  • Plots phase A voltage, current, and motor speed on a canvas using quadratic curves for smooth rendering.
  • Simulates current measurements based on motor impedance.
  • Covers electrical (inverter, PWM), mechanical (motor dynamics), and thermal aspects.

Second version

  • Key steps :—
  • Model of motor :—
    • Models an induction motor using a simplified d-q axis framework (Clarke-Park transform).
    • Calculates torque, speed, and rotor flux based on phase voltages and currents.
    • Includes thermal modeling, adjusting resistance based on temperature and simulating heat generation and cooling.
    • Supports different load types (Constant, Fan/Pump, Inertia) with configurable mechanical parameters.
  • Inverter & Control system :—
    • Generates phase voltages from PWM signals, accounting for dead time, modulation index, harmonic injection, and overmodulation.
    • Maintains a constant voltage-to-frequency ratio with PI control for speed regulation.
    • Uses d-q axis control for precise torque and flux regulation.
    • The inverter includes thermal modeling for switching losses and cooling effects.
  • Data logging :—
    • Buffers simulation data and periodically writes to a CSV file (simulation_data.csv), with error handling for file I/O.
  • Visualization :—
    • Plots phase A voltage, current, and motor speed on a canvas, using a sliding window of 1000 point salongside smooth rendering.
  • Sensor modeling :—
    • Simulates current sensors with Gaussian noise and partial/complete failure modes.
    • Currents are calculated based on motor impedance, adjusted for noise and failure scaling.
  • Models a wide range of components (motor, inverter, sensors, faults) with realistic dynamics, including thermal effects and noise.
  • Supports multiple control strategies (V/f, FOC) and load types, making it versatile for educational and engineering purposes.

Third version

  • Covers electrical, mechanical, thermal, and fault aspects of an inverter drive system.
  • Includes thermal dynamics, PWM effects, and fault simulation
  • Plots three-phase voltages, currents, and motor speed on a canvas.
  • Logs simulation data (time, voltages, currents, speed, torque, control mode, fault) to a CSV file.
  • Uses a buffer to reduce disk I/O, flushing when full.
  • Displays error alerts for I/O failures.
  • System modeling :—
    • Models electrical dynamics (d-q axis currents, rotor flux, torque) using simplified motor equations.
    • Includes mechanical dynamics (inertia, damping, friction, coupling stiffness).
    • Simulates thermal behavior using heat generation (I²R losses), convection, and radiation, with configurable cooling (fan speed, coolant flow).
    • Supports different load types (constant, fan/pump, inertia).
    • Comprehensive modeling of electrical, mechanical, and thermal aspects; realistic temperature-dependent resistance.
    • Generates three-phase voltages using pulse width modulation (PWM) techniques (SPWM & SVPWM).
    • Supports harmonic injection, overmodulation, and dead-time compensation.
    • Simulates current measurements with Gaussian noise and partial failure scaling.
    • Allows enabling/disabling sensor faults.
  • Control planning :—
    • V/f Control
      • Maintains a constant voltage-to-frequency ratio for open-loop speed control.
      • Uses PI control to adjust frequency based on speed error, with acceleration limits.
    • Field-Oriented Control (FOC)
      • Controls torque and flux independently using d-q axis voltages.
      • Employs PI controllers for speed, torque, and flux regulation.
      • Uses inverse Park-Clarke transforms for three-phase voltage generation.
    • Direct Torque Control (DTC)
      • Directly controls torque and flux using a switching table and hysteresis bands.
      • Estimates stator flux angle based on currents and rotor flux.
  • Fault simulation :—
    • Simulates faults like overcurrent, undervoltage, phase loss, overheating, and IGBT failure.
    • Applies fault effects to phase voltages (e.g., scaling, zeroing phases).
    • Supports protection modes (warning, shutdown) and auto-reset after a timeout.
    • Comprehensive fault coverage; realistic fault injection (e.g., intermittent IGBT failure).

Diese Software simuliert einen elektrischen Wechselrichterantrieb und ist in JavaFX geschrieben. Vor einigen Tagen (21. April 2025) ich habe eine ähnliche Desktop-App zur Simulation eines elektrischen Wechselrichterantriebs geschrieben, allerdings in der C-Programmiersprache und mit einem anderen Ansatz.

This software simulates electrical inverter drive and is written in JavaFX. Few days back (21 April 2025), I wrote a similar desktop app for simulating electrical inverter drive but I wrote that one in C programming language and with a different implementation.
