ANALYSIS OF REACTIVE POWER ON DIFFERENT BUSES OF A 57-BUS POWER SYSTEM

With the help of Load flow study all the power flow parameters can be find out of power system network .However so many methods are available to solve the load flow problems but accuracy and speed are the main problems in all techniques. By using the PSO we can improve the accuracy and speed then another method. By using PSO techniques we find the optimal location in the system at which we can set the reactive power compensating device .The paper conclude analysis of a load flow system of 57-bus network and find out the optimal location at which voltage deviation is minimum and use the thyrister ckt and facts devices for compensate the reactive power as per requirements. . The power flow study provides the system status in the steady-state and it is fundamental to the power system operation, planning and control. PSO is applied in a new computational model for the system power flow obtainment. This model searches for a better convergence, as well as a wider application in comparison with traditional methods as the Newton-Raphson method.
