Solution Overview
The extensive use of silicon-controlled rectifier and converter equipment in some port enterprises has resulted in a notable decline in the quality of the power supply and distribution. The high harmonics generated by these pieces of equipment resonate with the system capacitive reactance and impedance under specific conditions, which can cause serious damage to some of the equipment. The damage caused by harmonics to power supply and distribution systems is becoming increasingly evident. It is therefore imperative to suppress harmonics and improve the quality of power supply and distribution. Furthermore, the use of high-speed changes in the door machine and other loads means that traditional reactive power compensation devices are unable to effectively compensate for power factor. This results in increased energy consumption, higher electricity bills for users and greater costs for the industry.
