Operational capability of inductively loaded current controlled solid-state leadlag var compensator
Operational capability of the inductively loaded current controlled solid-state leadlag var compensator based on theoretical and experiments results for entire range of switching delay angle has been presented in this paper. The model is developed by deriving the mathematical equation of the input current of one of the three phases with respect to corresponding phase voltage. The Fourier analysis of the input current then gives the compensator performances such as var handling capability, magnitude of input and dc currents, etc. The operational limits of the var compensator have also been identified. The theoretical results have been verified with the experimental ones. The effects of energy storage and other circuit elements on the var compensator capability can also be studied from this model and hence the design of the compensator becomes simple.
