At present, this three-level inverter has been successfully applied to submersible pump drives in many oil fields. It has the following technical advantages: At different AC voltages and frequencies, the start, run, and stop of the motor are very smooth. Large inrush current; the device can meet the requirements of output power, flow rate and lift at a certain input voltage and output frequency, and the input power factor is close to 1. There is a significant energy saving effect; the speed of the inverter is increased under the condition of overclocking, and the motor power is increased. Greatly improved, you can achieve the purpose of increasing production. The new medium voltage drive submersible pump was put into operation by a high-reliability three-level 200kW medium voltage drive jointly developed by the Department of Electrical Engineering of Tsinghua University and Tianjin Huayun Industrial Control Co., Ltd., aiming at midpoint clamping and voltage jump. The key problem in multi-level inverters is to propose and implement VVVF software algorithm with practical engineering application value.
