"By using high precision,easily use,completely data post-processing software HIL platform which is supplied by ModelingTech, we have accomplished plenty of tests that are impossible or low efficient in traditional test methods.Such as L/HVRT,grid-tied test,new function verification.By using this HIL platform,our test efficiency is 10 times higher than traditional way.For some experiments that require repeated testing to obtain the data,HIL platform supplies rapidly,plentiful test data. We are expect StarSim Auto Test function helps us make further efforts of test efficiency! It’s also worth mentioning that the tech-support of ModelingTech is especially in time, help us solve many problems in power electronic simulation.”

Project Challenges

Conventional R&D progress, there is a large span between computer simulation and physical test.The sampling delay of physical test is not equal to computer simulation,in the same time ,computer simulation use the average modeling method in order to depress simulation time cost.But ripple can not be simulated by using this method,and the result is different with physical test,it’s hard to debug.

Conventional controller test progress,test only use single signal source to achieve open loop logical test,can not includes all the test class and not suit with whole system certification test.In traditional high power inverter controller test, for safety,the required equipment and experiment conditions are high requirements, requiring many people to assist,this method is time-consuming and laborious.In this method, it’s hard to retest after a fault test,and time consuming for engineers to obtain multiple sets of experimental data.

Solution

In order to solve the problems above, ModelingTech supplies a solution by using HIL simulation platform.In this solution the HIL simulator is connect with physical controller through the rich IO interface,the HIL simulator running the circuit model,achieve the close loop complete test of controller.reduce the span between model and physical platform.All of the test projects can be done by one engineer by using ModelingTech HIL simulator ,and the circuit parameters can be changed rapidly, multiple tests can be repeated in a short time,and save all the test data.

In the application of high power wind turbine grid-connected which includes grid side and turbine side converter.The switch frequency of both converter usually ranging in several kilohertz.The simulation step time of CPU based simulation typically in 20~30 us,can not accurate simulate power electronic converter detail model and resolute the PWM pulse duty ratio.In the wind turbine grid-connected impedance test,the transfer function is required,the delay is a vital part of transfer function.In order to acquisition more precision result,the small step simulation is needed to meet the low latency simulation requirements of users applications.

The whole wind turbine generator model not only includes power electronic part but includes some no simulation step time required model,such as torque computing,friction model,is suit to simulate on CPU.Integrated considerate,the Real-Time simulation of wind turbine generator system needs combine large step simulation on CPU and small step simulation on FPGA.

Eventually,ModelingTech supplies a solution that combines CPU&FPGA large&small step simulation based on MT 6040 Real-Time simulator.The combination of the ability to simulate not only power electronic converters in 1us steps (running machine side and network side converters and motors on the FPGA), but also user-defined low-speed (50us) mathematical models (running torque computing model, friction model, and other mathematical models on the CPU), perfectly simulates the entire system.
