Title:
METHOD FOR CONTROLLING A CYCLOCONVERTER, ELECTRONIC CONTROL DEVICE THEREFOR, CYCLOCONVERTER, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/007836
Kind Code:
A3
Abstract:
The invention relates to a method for controlling a cycloconverter (20), which is designed to a connect a first three-line network (30) to a second three-line network (31), wherein the cycloconverter (20) has six converter branches (32, 33, 34, 35, 36, 37) connected in series, in which converter branches electrical energy stores (9, 11) are provided, wherein the method comprises a method for converter operation control (41), by means of which the energy transfer from the first three-line network (30) into the second three-line network (31) or vice versa is controlled according to energy demand criteria, energy supply criteria, and/or reactive power criteria, wherein the method comprises a method for energy content control (42), by means of which the amount of electrical energy stored in each converter branch (32, 33, 34, 35, 36, 37) or an electrical variable that characterizes the amount of electrical energy is controlled to a specified target range. The cycloconverter has six converter branches connected in series, and said converter branches have energy stores. The invention further relates to an electronic control device for such a cycloconverter, to a cycloconverter, and to computer programs.
