Robust Compensating Function Scheme for Adequate Electrical Power System Stabilization

Abstract

This work centers on robust compensating function scheme for adequate electrical power system stabilization. There has been high level of disturbances in the power line and lack of adequate compensation technique to cancel the effects of the resultant instability which has caused power failures. The problem was addressed by the consideration of disturbances in the power line during the design of the compensating function for the improvement of the power system performance and stability. H-Infinity synthesis robust compensating function design method was used to design an adequate compensator that can improve the performance and stability of the power system. From the results, the H-infinity Synthesis Controlled Generating Plant (HCGP) recorded an overshoot of 0%, settling time of 1.04 seconds, tracking error of 0dB, gain margin of 21.7dB and phase margin of 79.6 degrees. The simulation was repeated by varying the value to k to -0.3, and the generating plant produced same results. This shows that the system can maintain performance and stability equilibrium even when there is change in its parameters. Since the HCGP satisfied the performance and stability robustness, therefore it was concluded that power system robust compensating function scheme for improved performance and stability robustness was achieved using H-Infinity synthesis method.

Analysis and Design of Cooperative Control Solutions for Electrical Systems of Laser CNC Machines

“…Macmammah et al said that the application range of CNC machine tools in the industry is constantly expanding, and it has many advantages compared with ordinary machine tools, but at present, CNC machine tools cannot completely replace ordinary machine tools, nor can they be the most economical way to solve all problems in the machining process [1]. Klausen et al said that CNC machine tools are mainly suitable for processing complex shapes and high precision requirements while producing parts with small batches but many varieties [2].…”
