Abstract |
The expanding improvement of sustainable power source challenges more and more the parameters of their connection to grid. Utilization of inverters to interconnect to the grid has become widespread for a number of power quality and distributed generation applications. The design of passive filters for such converters has not received as much consideration as that for control and operation of the semiconductor switches. Conventionally, First order L filter and second order LC filters are use but this filters are insufficient that is the reason to use LCL filter for grid conn. Design of filters used in grid-connected inverter applications includes a large number of constraints. The filter necessities are driven by tight tolerances of standards such as IEEE 519-1992 and IEEE 1547.2-2008. Higher order LCL filters are important to achieve these regulatory standard requirements at compact size and weight. The connection through an LCL filter deals certain advantages, but it brings also the disadvantage of having a resonance frequency. To overwhelmed the above drawback passive damping methods are used. |
