Active Reactive Power Flow Control Using Static Synchronous Series Compensator (SSSC)

Abstract

In present scenario, the performance of power systems decreases with the size, the loading and the complexity of the system networks. This is related to problems with power oscillations, large power flow and voltage instability with inadequate control, so the power flow control plays a major role in power systems. In this paper SSSC series FACTS device are regulates system voltage by absorbing or generating reactive power and the control of active, reactive power flow and voltage well as damping power system oscillations in long transmission line. In this paper results of SSSC series FACT device compared with the STATCOM shunt FACT device and Simulation studies were carried out in the MATLAB simulation environment to observe the compensation achieved by the SSSC device. The system parameters such as voltage, current, active power and reactive power transmissions are observed when the SSSC, STATCOM device is connected to the power system. For the simulation purpose, the model of two-area four-machine 11-bus system with SSSC and STATCOM device is developed in MATLAB/SIMULINK using Simpower System (SPS) blockset.

Comparative Study of Traditional Devices and FACTS Controller for Enhancing the Transient Stability Margin

“…Voltage stability can be classified into two sections particularly dynamic and static. The static voltage stability approaches are primarily relying on steady state model in the tests like the flow of power model [4]. Dynamic stability analysis presents the utilization of a model identified by nonlinear differential and algebraic equations comprises dynamics of generators, regulating transformers etc.…”

“…Dynamic stability analysis presents the utilization of a model identified by nonlinear differential and algebraic equations comprises dynamics of generators, regulating transformers etc. A lot of approaches have been employed in static voltage stability analysis like the P-V and Q-V curves, model analysis, artificial neural networks [4]. Line stability index (LSI) gives essential knowledge to find the critical line and closeness of the network to voltage instability in the power system.…”

“…SSSC is also applied for power system stability enhancement in a two-bus machine system [14][15], to control active and reactive power, along with damping of oscillations in a multi area power system [16][17]. The operation of SSSC for power flow control, its active and reactive compensation were carried out in the research extensively [18][19][20][21][22][23][24][25][26][27]. But, these researchers limited to simulation of the system with FACTS Devices.…”
