Siemens wind power develops software testing for wind turbine control system hardware in the loop simulator

test control system software

wind turbine system is composed of multiple components, including motor, gear, rectifier and transformer converter, which are used to convert dynamic wind energy into electric energy to reduce environmental pollution and resource waste

the control system connects these components of cervical artificial intervertebral disc proposed by the National Bureau of building materials industry through hundreds of i/o signals and multiple communication protocols. The most complex part of the control system is the embedded control software that executes the control cycle

since our software developers regularly release new versions of the controller software, we need to test the software to verify that these software will be reliably executed in the environment of the wind station. When each software is released, we need to accept the performance test in the factory before using the software on site. This new testing system enables us to automate this process

experience learned from the past system

our previous test system was developed 10 years ago, which is based on another software environment and PCI data acquisition board. The architecture and performance of the test system cannot meet our requirements for new test time and scalability. Maintenance is also very difficult, and effective testing cannot be automated. It also lacks the traceability of automatically generating documents for test results and testing, and does not provide the required remote control function. In addition, the past HIL test environment did not support multi-core processing, so we could not take advantage of the computing power of the latest multi-core processors

decision of future system

after evaluating the available technologies, we chose LabVIEW software and PXI based real-time field programmable gate array (FPGA) hardware to develop our brand-new test solutions. We believe that this technology will bring flexibility and scalability to meet our future technical needs. At the same time, we have built confidence in the solution from the service and product quality provided by Ni

since we have no in-depth development experience in testing internal systems, we will outsource the development to CIM industrial systems a/s company in Denmark. We chose CIM industrial systems a/s because they have test engineering capabilities and the largest number of LabVIEW certified architects in Europe. CIM has successfully developed this project, and we are very happy with the services we have received

flexible real-time test system architecture

the new test system provides simulation signals for the tested system by running component simulation models in the LabVIEW real-time module system to simulate the behavior of real-time wind turbine components

the main computer contains an intuitive LabVIEW user graphical interface, which can be easily adjusted by moving components in the panel. The windows operating system application communicates with two external instruments that are incompatible with real-time tasks

the software on the host computer communicates with the LabVIEW real-time target located in the pxi-1042q chassis through Ethernet. The LabVIEW real-time module runs simulation software that usually contains 20 to 55 parallel execution simulation DLLs. This solution can call user models developed using almost all modeling environments, such as NI LabVIEW control design and simulation module, the MathWorks, Inc. Simulink software, or ANSI C code. The typical execution rate of our simulation cycle is 24 MS, which provides a lot of margin to meet the future processing capacity expansion requirements

FPGA board for customized wind turbine protocol and sensor simulation

due to the lack of existing standards, many customized communication protocols are used in wind turbines. Using the multi-function Rio module based on Ni pxi-7833r FPGA and LabVIEW FPGA module, we can communicate with these protocols and simulate. In addition to protocol interaction, we use this device to simulate magnetic sensors and accurate three-phase voltage and current simulation. Other FPGA boards are connected with Ni 9151r series expansion chassis, further improving the number of system channels

advantages of the new test system

the new Siemens wind test system has many advantages over the previous generation solution. Due to the modularity of the system, it is very simple to improve, modify and further develop. The system under test can be quickly replaced without any change in the system architecture under test. The remote control function and the simple replication of the system make the internal surface roughness 0.32. We can flexibly replicate the system to other sites when we need to expand

The

simulator provides the environment with the ability to efficiently validate new software releases and test special solutions in the laboratory. It also gives us tools to test the new technologies and concepts we are studying

future plan

the modular architecture allows us to expand the system to meet the growing needs of changing wind energy technology. We plan to split the simulation into multiple LabVIEW real-time targets to meet our future testing needs. We also plan to use Ni TestStand for future automated testing. (end)
