Optimization of Co-ordination Control of FACTS Devices by Using Fuzzy Lead-Lag Controller
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
Power system stability control is an important task in power system operation. Several factors, such as external disturbances or internal mechanical torques, may easily affect the power system stability. Hence, the structural control of electric power networks has recently attracted more attention. FACTS devices are used to dynamically adjust the network configuration to enhance steady-state performance as well as dynamic stability. FACTS devices provide series or shunt compensation, but they interfere with one another when they are made to work together in a power system, causing damping oscillations in the line. In this paper, Thyristor-controlled series capacitor (TCSC) and the Static VAR compensator (SVC) are used for improving the power system stability. A novel approach of designing a controller which adaptively determines the parameters of two controllers at each control step according to the deviations of generator rotor speeds of the power system is developed to reduce the damping oscillations. The parameters are estimated by using the generator speeds and the monotonous time consuming and inaccurate process of human calculations is avoided, which has been used is proved to be more accurate than the conventional approach thus providing active power flow regulation and reactive power compensation.
