Review of Analysis of Power System Oscillation Damping &Voltage Stability Improvement Using SSSC In A Multi-Machine System

Authors(2) :-Amit Kumar, Pardeep Nain

The planning and operation condition of electrical power systems are changing due to a variety of causes. FACTS controller helps in raising dynamic stability limit and provide better power flow control. Static synchronous series compensator (SSSC) is one of the important members of series FACTS controller. In this paper is presented the effect of SSSC for damping power system oscillation. Interconnection of electric power systems is becoming increasingly widespread as part of the power exchange between countries as well as regions within countries in many parts of the world. There are numerous examples of interconnection of remotely separated regions within one country. In cases of long distance AC transmission, as in interconnected power systems, care has to be taken for safeguarding of synchronism as well as stable system voltages, particularly in conjunction with system faults. With series compensation, bulk AC power transmission over very long distances (over 1000 km) is a reality today. These long distance power transfers cause, however, the system low-frequency oscillations to become more lightly damped. As a result, many power network operators are taking steps to add supplementary damping devices in their systems to improve the system security by damping these undesirable oscillations. With the advent of voltage sourced converter-based series compensation, AC power system interconnections can be brought to their fullest benefit by optimizing their power transmission capability, safeguarding system stability under various operating conditions and optimizing the load sharing between parallel circuits at all times. This Paper reports the results of simulation studies that are carried out to investigate the effectiveness of a three phase Static Synchronous Series Compensator (SSSC) compensation scheme in damping power system oscillations in multi-machine power systems. Application of static synchronous series compensator (SSSC) based damping controller for enhancement of power system stability is throughout investigated in this paper. SSSC is effectively utilized for power flow control in the power system. A SSSC-based damping controller is proposed for rotor angle stability enhancement and to eliminate the power oscillation damping in power system. To improve the rotor angle stability and power oscillation damping in system an supplementary signal can be superimposed as a power flow control signal for SSSC damping controller. Speed deviation of rotor is taken as the input signal to the SSSC damping controller
