TATCOM is mainly used to provide dynamic reactive power and voltage support to the power grid. The device connects a voltage-source converter in parallel to the power grid through a reactor or transformer, automatically adjusts the amplitude of the output voltage on the AC side of the converter, rapidly absorbs or generates the required reactive power, and achieves the purpose of rapid dynamic voltage regulation and enhancing the stability of system operation.

The STATCOM products are mainly targeted at overseas markets and international customers in the field of new energy AC grid connection, and have been exported to regions such as Europe, America, Oceania and Africa. The large-capacity high-voltage active power filter (HAPF) developed by the company will be first applied in the Fujian-Guangdong interconnection DC project jointly carried out by State Grid and Southern Power Grid, to solve the problem of harmonic amplification in conventional DC converter stations and ensure the stable operation of the DC system. The sub-synchronous resonance suppression device (SSR-DS) launched by the company is mainly aimed at power plant customers. It uses dynamic reactive power technology to effectively suppress the occurrence of sub-synchronous resonance caused by new energy grid connection and other reasons, prevent damage to the turbine shaft system, extend the service life of the unit, and ensure the safety of power generation. The company is one of the first domestic manufacturers to apply this technology.
