The EasyGo new energy real-time simulation system is designed to provide an innovative experimental platform with leading technology and excellent performance for undergraduate and graduate students majoring in new energy-related majors. The innovative experimental base built based on this construction plan can assist undergraduate and graduate students in teaching and experiments in related professional courses and elective courses.

1. Platform architecture

EasyGo new energy real-time simulation system is a model in the loop experimental system, which is the digitization and virtualization of various existing teaching and scientific research laboratories. Its basic principle is to use a real-time simulator running a mathematical model to simulate the characteristics, behaviors and various working conditions of the actual new energy system, and at the same time verify the control algorithm model through a fast controller. The two are connected through the actual I/O interface to perform closed-loop test verification.

2. System composition

The new energy real-time simulation innovation system consists of 4 parts:

▍Real-time simulator EG-Box-Mini K1011

The controlled object (power electronic circuit system and topology) built with the Simulink modeling environment can be simulated in real time on the FPGA hardware configured in the chassis, the characteristics of the controlled object can be simulated and the signal can be fed back to the control side to complete the closed loop of the experimental system, or combined with the actual circuit module to complete the closed loop operation of the entire system.

▍Rapid prototyping controller EGBox-Mini K0111

It is used to implement the Simulink control algorithm needed in the simulation experiment, send control signals to the real-time simulation chassis, and form a closed-loop experimental system for control theory experimental courses.

▍MIL signal adapter box

Used to transmit signals between the simulator and the controller, it is equipped with a BNC observation terminal to facilitate students to observe actual signals and intuitively understand the operating principles of the system.

▍Upper computer

3. EGBox-Mini product series

EGBox-Mini is the entry-level product in the EasyGo real-time simulation product series. It adopts an integrated portable design, which is convenient for rapid development and testing on the laboratory table. Based on its multi-core real-time CPU+FPGA hardware architecture, it is convenient to connect with actual equipment to perform hardware-in-the-loop testing.

Among them, EGBox-Mini k0111 is used as RCP rapid prototyping controller, and EG-Box-Mini k1011 is used as HIL real-time simulator.

4. Experimental routine

The real-time simulation experiment system provides supporting experimental course routines and routine instructions. Based on the openness of the platform, in addition to the 20 new energy-related experimental routines provided, users can also add more teaching or innovative experimental content.

All experiments include offline programs, real-time control algorithm programs, circuit simulation real-time programs, etc. Among them, the simulation side model uses a real-time simulator to achieve 1 microsecond high-speed simulation operation; the control side uses a rapid prototype controller to run the corresponding control program.
▍Simulation verification

In real-time simulation verification, the model is divided into a CPU part and an FPGA part. The parameters of the entire real-time simulation process can be adjusted online, as well as an online waveform observation interface.

When using a real-time simulator to simulate the controlled object model in real time

The CPU part uses a 100us step size to perform real-time simulation of various battery, photovoltaic module, wind turbine and other models, and the FPGA part uses a small step size (0.2-1.5μs) to run the motor and power electronic equipment models.

When using rapid prototyping controllers for real-time simulation of control algorithm models

The CPU part uses a 50-100us step size to perform real-time simulation of the control algorithm model, while the FPGA part performs high-speed PWM generation, motor encoder reading, and other tasks.
