Harmonic Filter Design for Hvdc Lines Using Matlab

This paper presents harmonic filter design for HVDC lines using MATLAB version R2009a.Non-linear devices such as power electronics converters can inject harmonics alternating currents (AC) in the electrical power system. The number of sensitive loads that require ideal sinusoidal supply voltage for their proper operation has been increasing. To maintain the quality limits proposed by standards to protect the sensitive loads, it is necessary to include some form of the filtering device to the power system. Harmonics also increases overall reactive power demanded equivalent load. This paper deals with the design of three phase filter banks connected in parallel to achieve optimal control for harmonic elevation problems.
