Direct Voltage Control in Distribution System using CMLI Based STATCOM

Authors: Jagdish Kumar

This article presents a technique using system identification for the determination of transfer functions of a CMLI Static Synchronous Compensator used in power systems for the design of parameters of controllers in order to minimize voltage fluctuations and capacitor voltage balancing. The transfer functions obtained using system identification technique have been used for the determination of controllers’ parameters for load bus voltage and capacitor charge balancing using Ziegler-Nichols technique. Digital simulation on an 11-level CMLI based Static Synchronous Compensator is carried out using MATLAB/SIMULINK for different load combinations using PI controllers’ parameters as obtained corresponding to identified model. It is found that simulation results obtained using identified model give good performances.
