Good news
Jiangsu Ankerui Electric Appliance Manufacturing Co., Ltd., a wholly-owned subsidiary of Acrel Co., Ltd., has recently obtained a patent certificate for invention issued by the State Intellectual Property Office. Details of the patents obtained are as follows:
Title of invention: Open loop control method of high speed harmonic current based on current prediction feedforward and multi-PR resonant branch
Certificate No. : 5117532
Patent Number: ZL 2018 1 1379798.X
Patent filing date: November 20, 2018
Patentee: Jiangsu Acrel Electrical Appliance Manufacturing Co., LTD. Southeast university
Authorization Announcement Date: April 29, 2022
Patent term: twenty years (from the date of application)
The invention discloses a kind of based on predictive feedforward current PR more resonance branch of the harmonic current closed-loop control method, to ensure that does not affect the current loop under the premise of the steady state performance, can obviously improve the current loop dynamic characteristics, and compared with the traditional APF current loop control method of the invention method is simple and easy to implement, It provides effective technical support for harmonic control of nonlinear impact load and has good feasibility and practical value.
Ankerui harmonic management of the main products active power filter, low-voltage reactive power compensation device, static reactive power generator, hybrid dynamic filter compensation device, hybrid dynamic harmonic elimination compensation device, intelligent dynamic reactive power compensation device, harmonic protector, etc. For new construction, rebuilding and expansion and technological upgrading projects in industrial and civil and public buildings electrical equipment of reactive power compensation and harmonic suppression and the comprehensive treatment and so on, can according to different industry type and load of power quality problems provide appropriate design solutions, to improve the quality of power supply and to ensure the safe and economic operation of power system.
