Static Var Generator (SVG) Real-time simulation

Chain SVG, also known as static var generator, is a device that uses a bridge converter composed of fully controlled power electronic devices to perform reactive power compensation. It has been widely used in wind power generation, photovoltaic power generation and other renewable energy field stations. At present, SVG has become an indispensable equipment in wind farms, photovoltaic power stations and other renewable energy stations, but also nowadays renewable energy station testing must be tested, in each renewable energy testing organisations are using semi-physical simulation platform for testing. However, SVG systems usually have high voltage level, large power capacity, many cascaded sub-modules, many switches, etc. Based on the characteristics of the physical platform, the testing cost is high, the cycle time is long, the risk factor is high, and the project is complicated.

System Schemes

MT 8020 simulator is used to simulate static var generator (SVG) topology. The cascaded modules in the chain SVG topology run on the FPGA of the simulator with 1μs timestep. By this way the simulator can accurately simulate the operating characteristics of the chain SVG. The SVG controller, MT 2016 protocol converter and the simulator interact data information through optical fiber, and the grid voltage, current and other network information are sampled through the physical IO interface, thus realizing complete HIL simulation construction of the chain SVG.
