Latest Patents
One of Lei Wang's latest patents is titled "Hybrid STATCOM with wide compensation range and low DC-link voltage." This invention provides compensating reactive power required by a load through a hybrid-STATCOM design. The hybrid-STATCOM consists of a TCLC part for each electric power phase, which includes a coupling inductor, a power filter capacitor, and a thyristor-controlled reactor connected in series with a power filter inductor. Additionally, it features an active inverter part that comprises a voltage source inverter for each electric power phase and a DC-link capacitor connected in parallel with the voltage source inverters. The control strategy of this hybrid-STATCOM is divided into two parts: TCLC part control and active inverter part control, aimed at improving overall performance under varying voltage and current conditions.
Another significant patent by Lei Wang is the "Thyristor controlled LC compensator for compensating dynamic reactive power." This invention addresses the need for dynamic reactive power compensation in power grid systems. The TCLC compensator is shunt-connected to the three-phase power grid and includes an electronic controller, a coupling inductor, and a circuit with parallel inductors and capacitors. The electronic controller is designed according to the generalized instantaneous reactive power theory, enhancing response speed compared to traditional methods.
