The Stability

The paper is devoted to the stability and feasibility boundary evaluation. New technique for evaluating shortest distance to feasibility boundary is described and tested. The technique is based on analysis of Jacobi matrix form the power flow routine. Described technique can be applied together with PMU-based identification procedures leading to new opportunities for on-line power system stability monitoring.

Damping Controller

At present, power demand is increasing day by day so we have to transfer more power and for this we must have to improve stability limits of our power system. In this paper application of static synchronous series compensator (SSSC) for enhancement of power system stability is throughout investigated. SSSC is effectively utilized for power flow control in the power system. A SSSC-based damping controller is proposed for power oscillation damping and to improve the rotor angle stability. A improved control signal can be superimposed as a power flow control signal for SSSC damping controller to improve the rotor angle stability and power oscillation damping in system. Speed deviation of rotor is taken as the input signal to the SSSC damping controller. A single machine infinite bus system (SMIB) with SSSC is simulated in MATLAB/Simulink software. Simulation results shows the effectiveness of this controller for power system stability enhancement under different fault conditions.

Parsing Algorithm

Power flow solution is one of the most important means of power system stability analysis. While parsing algorithm is the basis of power flow analysis. The idea of iteration is frequently used in power flow solution because of the characteristics of power system itself. Textbooks, however, use the gradual iterative thought without rigorous demonstration of the conditions for convergence. From the point of view of mathematical analysis, the article not only gives a proper way to determine the convergence or divergence of the power flow but also provide the exact solution of a simple power flow with an example to demonstrate the validity of the algorithm.
