| Static reactive power compensators (SVCs) have been widely used to improve voltage and power factor ratios in factory and industrial substations. Therefore, these two functions are independent of each other and it is necessary to improve the power factor in order to regulate the voltage. In this paper, the new SVC startup method for induction motors is suggested. In this method, the amount of reactive power is precisely and controllable according to the load requirements. A hybrid controller includes slow suspension control and rapid voltage control that gives the SVC the ability to achieve power factor correction and creates a constant voltage characteristic during the start of the large induction motor. An ideal compensation method is recommended for both optimal voltage regulation and power factor correction. A case study on the operation of a large 1.4MW induction motor is presented with several startup methods. The comparative study is done by simulation with MATLAB software for different startup cases. Finally, the results of safe and reliable performance simulation guarantee the proposed method for effective design of operational posts. |
