Design of a multilevel inverter on power system performance using interline power flow controller.

There is a large increase in power demand and by using Flexible AC transmission systems (FACTS) controllers various steady state control problems in power system can be resolved. In FACTS devices converters form the main component. Apart from the existing multilevel inverters here a new design of inverter is proposed which aims at reducing the number of switches and thus reducing the switching losses. The scheme proposed here is used on an Interline Power Flow Controller (IPFC). The inverter can produce the pulses with different width and magnitude and the output almost resembles a sine wave. The proposed multilevel inverter is applied to an IPFC for protecting voltage sags, swells and momentary interruptions. The dynamic performance is analyzed and verified through MATLAB/SIMULINK.
