Static var generator (SVG) have been widely used in new energy field stations such as wind power generation and photovoltaic power generation due to their advantages such as fast response speed and continuous adjustment of reactive power. At the same time, various manufacturers are constantly developing and iterating a new generation of serialised SVGs. However, optimising and upgrading the product faces many challenges, such as the use of physical test platforms to validate the entire function of chained SVG devices, which has the drawbacks of a long construction period and high risk and cost.
ModelingTech has been deeply engaged in real-time simulation of power electronics for many years, and combined with the SVG related technical standards, it has developed a brand new function of 1us small-step SVG solver, which helps SVG manufacturers to efficiently develop, iterate, and test new products, and can verify the function of the controller of chain-type SVG device, which can effectively shorten the development cycle of the device, with controllable risk and low test cost.
With the help of MT real-time simulator and the newly launched SVG solver, the 40-stage chain SVG system can be simulated and tested. The SVG system runs in 1us simulation step in MT8020, and the SVG controller runs the SVG control algorithm and sends out PWM signals to the SVG system, The MT 8020 interacts with the SVG controller via optical fibre to achieve SVG hardware-in-the-loop simulation testing, providing a perfect solution for SVG manufacturers to conduct SVG network testing.
1us small-step SVG real-time simulation, free to configure any level of chain SVG model, low-latency, high-precision simulation of SVG operating characteristics
Industrial common Aurora 8b/10b protocol, support custom configuration of frame data content, high-speed transmission of SVG module voltage, PWM signals and other information.
Equipped with ultra-high-performance MT 8020 real-time simulator, combined with fibre-optic parallel simulation, LC solver, CPU multi-core simulation technology, to achieve station-level system testing.
Independently developed SVG solver can be quickly expanded to MMC simulation, which is convenient for users to test multi-level and large system applications.
