Method for controlling a network static converter with voltage intermediate circuit

摘要

A process for the regulation of the network static converter of a converter with a voltage intermediate circuit, in that in a function of the network voltage - and the network current parameters, with the use of current components regulators for the active current - and the reactance, the network current richter input voltage for the realization of a constant intermediate circuit voltage is regulated by the out (in 1, in2, in3) by means of a current coordinates transducer (2) and a subsequent first vector rotators (4) in an active component (ind) and a reactive component (inq), with the corresponding desired values (ind _, is intended to be compared inq _,), wherein the active current should value (ind _,) by the intermediate circuit voltage regulators (7) from the difference between the nominal value (u _,) and the actual value (u _ is) of the intermediate circuit voltage is provided, and in the current components regulators (8, 9) output variables (y d, yq) are formed while the network voltage value (and) from the power supply voltages (un1, un2, un3) by means of a first voltage coordinates transducer (1) and a vector filter (3) is formed, which with the two nominal current values (ind _ if, inq _,) and the network circle frequency (ωn) a decoupling network (10) which is parallel to the two current components regulators (8, 9) is arranged, and the network parameters..
