Sichuan Weinasa Technology Co., Ltd.  

Sichuan Weinasa Technology Co., Ltd. was established on September 28, 2017. The company is mainly developing a high-voltage reactive power compensation control method based on three-level inverter technology, which belongs to the field of power quality management. A high-voltage reactive power compensation control method based on a three-level inverter technology includes: detecting the reactive current that needs to be compensated by the system, and recording the signal value obtained by the current hysteresis controller as the current state, and calculating 27 inverses respectively After the transformer voltage vector is applied, the reactive power variation of the system is compared with the result obtained by the hysteresis controller. In this case, the applicable inverter voltage vector is selected. In addition, if there are multiple vectors satisfied, a universal setting is set. The determination method is solved to select the optimal action vector among the 27 inverter voltage vectors. The use of three-phase three-level inverter technology reduces the maximum voltage that the power electronic components can withstand and can be used in high-voltage reactive power compensation devices.
