Simulation and Analysis of Power Flow and Stability Control Using Stabilizer Multi-Band

The solution of the power flow is one of the most critical problems in electrical power systems. The power demand increases drastically due to industrialization and the electric transportation system. It makes the power system complex which needs to be properly controlled and maintain quality to flow. The effective control and operation of power remain challenging due to the variation in the input and load demand energy and the significantly high peak-to-average power ratio. Therefore, the rated power control is essential for the operating time and power output. The present rated power control method is based on the instantaneous rotational speed of the turbine generator. However, due to practical infrastructure limitations, such as the valve operating time, a more refined rated power control method is required. Flexible ac transmission systems are extensively installed in power systems to maintain a quality power supply. The Stabilizer multi-band has a key role in the improvement and control at the turbine power generating station. This paper presents simulation results of a Synchronous machine, Turbine Excitation Regulator, and Stabilizer multi-band for a 735 kV power line with the help of MATLAB/simulation module.
