Abstract: In order to improve the high-efficiency driving performance and good control characteristics of fishing equipments, this paper has researched the power control technology for trawl winch. The control scheme of variable frequency speed regulation system was designed with vector control method based on the demand analysis of trawl winch, which controlled winch through the coordination of PLC and inverter, and the key technology of the control system was also analyzed. According to the design scheme, the devices of system experiment were built up, which used the torque measurement devices to get the relationship among torque, power and speed change. During the test process, the speed regulation was stable, and winch could output constant torque under the rated voltage, so as to rapidly respond to load changes. The control system is stable and reliable, with the function of high automation, and has great prospect in the application of fishing equipments.
