Abstract


This paper briefly describes the composition, structure and basic working principle of the TCR FC static var compensator device . The basis of detailed analysis of the compensation principle of the symmetrical component method , deduced for the SVC digitized reactive power compensation formula , this algorithm is used to calculate the current instruction , is the basis of design SVC controller . In order to further improve the conditions to ensure the control precision fast reactive power compensation for TCR FC type SVC adaptive inverse control method . After in-depth analysis of adaptive inverse control method , using LMS adaptive algorithm , for control objects TCR characteristics of object modeling and inverse modeling to determine the structure of adaptive inverse control system , and its simulation verification. Adaptive inverse control method is applied to the SVC control system , under the simulation the software MATLAB SMULINK environment control system simulation model shows the simulation results , the results show the feasibility and effectiveness of adaptive inverse control scheme . Write Advantech IPC for experimental control core platform , suitable for the control platform software program , in this experimental platform to complete the experiment shows the experimental results of the waveform . Experimental results show that SVC controller using adaptive inverse control method in the three-phase equilibrium or in the three-phase unbalance conditions , the dynamic process of compensation are soon to reach steady-state voltage current basic same phase , high precision , steady-state performance and dynamic performance , can adapt to different load conditions , with good robustness is a very effective control program . DSP IPC has many advantages compared to the end of this article describes the DSP platform .
