The 50kvar and 100kvar SVG adopts modular design. When multiple units are expanded, master-slave control is adopted. When multiple modules are connected in parallel, all modules share a set of current transformers, which can realize multiple functions such as reactive power compensation, active filtering and three-phase imbalance. It automatically adjusts the output according to the harmonic current of the load, dynamically filters, and adopts independent air duct design. Dust and rain will not adhere to the circuit board, which is suitable for use in harsh environments. The instantaneous response time is less than 0.1ms, and the full response time of device compensation is less than 20ms. The output filter adopts LCL structure to access the power grid. Its own high-frequency carrier will not be fed back to the power grid, and there is no interference with other equipment in the distribution system. It has a soft start control circuit to avoid excessive inrush current at the moment of starting and limit the current within the rated range. The module is installed in the cabinet and can be monitored centrally with a high-definition 7-inch touch screen. It is easy to operate. The screen displays the system and device operating parameters in real time, and has a fault alarm function.
